LDC Series, SLD Series: LED Driver

LDC-80DA linear LED driver MEAN WELL LDC-80DA is a 80 W DALI and PUSH dimmable linear LED driver with resistor-selectable constant-current output from 700 to 2100 mA (1400 mA factory default). Match the LED string to the 27–56 V operating envelope and the selected current; the rated power and the catalog I–V boundary must both be respected. Download MEAN WELL LDC-80 Datasheet (PDF)Download MEAN WELL LED Installation Manual SLD/LDC catalog, PDF pages 37–45; LDC-80 specification dated 2026-02-09. The suffix identifies the fitted control interface. Output and current selection Model and function LDC-80DA; DALI and PUSH dimmable. Slim metal housing, active PFC and a catalog flicker-free design with low output-current ripple. Rated output power 80 W maximum within the published constant-power operating envelope. No temporary overload or peak-power rating is specified. Output current region 700–2100 mA; factory default 1400 mA. Preset the rated current with an external resistance across IADJ, rather than a DIP switch. Constant-current voltage region 27–56 V, subject to the current-setting I–V diagram. The low-current corner has a higher minimum voltage; the whole voltage/current rectangle is not usable. Select the LED string inside the shaded operating area. Full-power current range 1400–2100 mA as listed in the specification; output voltage × current must remain at or below 80 W and inside the I–V boundary. Open-circuit voltage 60 V maximum. Low-frequency current ripple 3.0% maximum at rated current. Current tolerance ±5.0%. Current-setting connection Connect the setting resistor between TB2 pins 7 and 8 (IADJ). The table below lists catalog nominal values. NC means an open setting-resistor connection, which gives 700 mA; it is distinct from the stated factory default. Select the current to match the LED load and its operating voltage. External IADJ resistance → nominal current 18.7 kΩ 2100 mA 23.2 kΩ 1900 mA 28 kΩ 1750 mA 34 kΩ 1600 mA 46 kΩ 1400 mA 68 kΩ 1200 mA 103 kΩ 1050 mA 188 kΩ 900 mA NC / open 700 mA Input and electrical performance AC input 180–295 VAC, 47–63 Hz. The current specification publishes no DC input operating range. Input/load derating At 60 Hz, the static-characteristic plot shows 100% load over 180–295 VAC. Temperature and I–V operating limits still apply. Setup time 500 ms at 230 VAC. Measured at the first cold start; switching the supply ON/OFF can increase setup time. Efficiency 90% typical at 230 VAC, full load. Power factor Typical PF ≥0.95 at 230 VAC and load ≥50%; PF ≥0.92 at 277 VAC and load ≥75%. Total harmonic distortion THD <10% at load ≥50% on 230 VAC, or load ≥75% on 277 VAC. AC current (typical) 0.48 A at 230 VAC; 0.36 A at 277 VAC. Inrush current (typical) Cold start 55 A at 230 VAC; 300 μs pulse width measured at 50% of peak current, per NEMA 410. Circuit-breaker reference At 230 VAC: up to 6 units on a 16 A type B breaker, or 11 on a 16 A type C breaker. The installation manual bases its matching values on ABB S200 breakers; verify the actual breaker and installation. Leakage current <0.75 mA at 277 VAC. Low-load power Catalog no-load/standby consumption <0.5 W. ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control DA suffix: primary-side DALI interface and PUSH dimming. Do not use DALI and PUSH at the same time; the factory mode is DA. DALI operation Apply the DALI signal between DA+ and DA−. The catalog describes 16 groups and 64 addresses; the first step is fixed at 8% of rated output power. Compliance is stated with IEC 62386-101, -102 and -207 for DA type. DALI/PUSH terminals TB1 pin 6 = DA− / N; pin 7 = DA+ / Ls. These are primary-side control terminals; they are not the B variant’s secondary DIM+/DIM− terminals. PUSH connection Use a retractive push-to-make switch between Ls (DA+) and AC/L; connect N (DA−) to AC/N as shown. Do not connect the pushbutton between Ls and AC/N: the catalog warns this causes a short circuit. PUSH timing Short push 0.1–1 s: ON/OFF. Long push 1.5–10 s: dim up/down, reversing direction with each long push. Reset >11 s: set dimming level to 100%. Actions shorter than 0.05 s do not change status. Factory dimming level: 100%. PUSH system limits Up to 10 drivers can share one pushbutton; maximum cable length from the button to the last driver is 20 m. DALI wiring conditions Confirm DALI controller and network compatibility. For standalone use, dimming conductors smaller than 18 AWG (0.75 mm²) require SELV controllers/networks under the installation manual; seek manufacturer guidance for FELV. This control-network rule does not replace the catalog’s mains-referenced PUSH wiring or its insulation requirements. Temperature compensation, protection and environment NTC connection Connect an external temperature-sensing NTC across TB2 pins 5 and 6, with its sensing point on the lighting system or surrounding environment. Without an NTC, the driver runs at the current selected through IADJ. NTC characteristic Below 17.5 kΩ, output current decreases as NTC resistance decreases; above 17.5 kΩ, output current remains normal. The table does not specify the exact equality point. MEAN WELL does not supply the NTC; the published values were measured using resistance. Check the temperature curve when selecting a new NTC brand. NTC/control interaction The catalog states that dimming is invalid while temperature compensation is in use. Short-circuit protection Hiccup mode or constant-current limiting; automatic recovery after the fault is removed. Overvoltage protection 61–80 V. Output shutdown with automatic recovery or recovery after re-powering, as stated in the catalog. Overtemperature protection Output shutdown with automatic recovery. Case-temperature range Tcase −25 to +85°C; maximum case temperature +85°C. Measure at the marked tc location in the mechanical drawing. Ambient/load derating Horizontal mounting: 100% load from −25 to +50°C; the plotted points are 80% at +60°C and 60% at +65°C. The ambient curve ends at +65°C. Meet both ambient-load and maximum-case-temperature limits; a case-temperature rating is not an unrestricted ambient rating. Case/load curve The horizontal-mounting case curve remains at 100% through +85°C and ends there. This does not override ambient-temperature derating. Cooling and altitude Free-air convection. Nonstandard mounting or higher ambient temperature may require further current derating. Above 2000 m altitude, reduce the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless driver. Working humidity 20–95% RH, non-condensing. Storage conditions −40 to +80°C; 10–95% RH. Temperature coefficient ±0.03%/°C over 0–60°C. Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis. Performance-plot conditions PF, THD and efficiency plots use Tcase 75°C. THD and efficiency examples use a 1400 mA setting; they do not replace the tabulated typical efficiency or the operating envelope. Lifetime reference Typical life expectancy >50,000 operating hours when Tcase, especially at the marked tc point, is about 75°C or less. Lifetime decreases with increasing case temperature; this is a catalog operating-life reference, not a separate warranty duration. MTBF 2321.4 K hours minimum, Telcordia SR-332 (Bellcore); 259.2 K hours minimum, MIL-HDBK-217F at 25°C. Mechanical installation and terminals Dimensions 360 × 30 × 21 mm (L × W × H); metal case 264A. Mechanical drawing tolerance ±1 mm. Mounting geometry Two Ø4.5 mm end mounting locations, 353 mm center spacing, 3.5 mm from each end; use the exact drawing and allow ventilation. TB1 input terminals Pin 1 = AC/L; pin 2 = AC/N; pin 3 = NC; pin 4 = FG. Connect FG to protective earth. TB1 control terminals Pin 5 = NC; pin 6 = DA− / N; pin 7 = DA+ / Ls, listed for DA type only. Follow the separate DALI or PUSH circuit and do not mix control modes. TB2 output and adjustment Pins 1–2 = Vo+; pins 3–4 = Vo−; pins 5–6 = NTC; pins 7–8 = IADJ. Observe LED polarity and do not exceed the selected current/power envelope. Conductor and strip lengths TB1: 0.5–0.75 mm²; TB2: 0.2–0.5 mm². Strip 8–9 mm for each terminal block. Use approved conductors with adequate current rating and system insulation. Unit mass reference 295 g per unit, converted from the catalog PACKING single-unit reference. This is not a measured shipment or carton weight. Safety, EMC and specification conditions Construction and safety SELV output and Class 2 power-supply design are stated in the catalog. Class 2 does not remove the fitted FG/protective-earth connection requirement.

Specification conditions Unless specified otherwise, parameters are measured at 230 VAC input, rated current and 25°C ambient. The driver is a component for integration into final equipment, whose complete installation must be requalified for EMC. Warranty The manufacturer catalog states a 5-year warranty, subject to MEAN WELL’s warranty statement and applicable conditions. Installation and selection notes Installation safety Disconnect the mains supply and prevent accidental reconnection before installation or maintenance. Have faults examined by a qualified technician; do not open the power-supply case yourself. Ventilation and mounting Keep ventilation clear and do not stack objects on the unit. Keep 10–15 cm clearance when the adjacent device is a heat source. Follow this model’s mounting, ambient-temperature and output-derating requirements. System wiring and protection Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system. Connect a fitted FG terminal to protective earth; the manual exempts only units marked Class II and ungrounded. Environmental and load limits Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person. Selection and accessories Choose the complete suffix for the required control interface. The current catalog does not give a dedicated MEAN WELL accessory order code for this driver. External setting resistors, NTC sensors, dimming controllers and pushbuttons must be selected for the actual interface; the NTC is explicitly not supplied by MEAN WELL. Applications Linear lighting and LED fixtures such as office, panel and indoor lighting applications, subject to the fixture design, electrical ratings and thermal conditions.

ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control B suffix: 3-in-1 dimming by 0–10 VDC, a 10 V PWM control signal, or resistance between DIM+ and DIM−. Connect directly to LEDs; additional LED drivers are unsuitable. PWM control frequency 100 Hz–3 kHz for the external 10 V PWM input. This is a control-signal frequency, not a stated LED output PWM frequency. Dimming source current 100 μA typical from the driver. Dimming range Minimum dimming level is about 8%; output current is undefined for 0% < Iout <8%. Output can fall to 0% at about 0 V control input or 0% duty of a 10 V PWM signal. For low-level dimming performance, output current must be over 80 mA. Resistance control The graph gives 10 kΩ/N for 10% and 100 kΩ/N for 100% output current, where N is the number of drivers in synchronized dimming operation. Use the actual characteristic, including its undefined low-level region. DIM terminal restrictions TB2 pin 9 = DIM+; pin 10 = DIM−. Never connect DIM− to Vo−. The LED installation manual identifies the LDC secondary dimming circuit as not isolated from the secondary output. Controller installation Confirm controller compatibility and current capacity. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), the installation manual requires SELV controllers/networks; contact MEAN WELL before using FELV control.

LDC-55DA2 linear LED driver MEAN WELL LDC-55DA2 is a 55 W DALI-2 and PUSH dimmable linear LED driver with resistor-selectable constant-current output from 500 to 1600 mA (1050 mA factory default). Match the LED string to the 27–56 V operating envelope and the selected current; the rated power and the catalog I–V boundary must both be respected. Download MEAN WELL LDC-55 Datasheet (PDF)Download MEAN WELL LED Installation Manual SLD/LDC catalog, PDF pages 28–36; LDC-55 specification dated 2026-02-09. The suffix identifies the fitted control interface. Output and current selection Model and function LDC-55DA2; DALI-2 and PUSH dimmable. Slim metal housing, active PFC and a catalog flicker-free design with low output-current ripple. Rated output power 55 W maximum within the published constant-power operating envelope. No temporary overload or peak-power rating is specified. Output current region 500–1600 mA; factory default 1050 mA. Preset the rated current with an external resistance across IADJ, rather than a DIP switch. Constant-current voltage region 27–56 V, subject to the current-setting I–V diagram. The low-current corner has a higher minimum voltage; the whole voltage/current rectangle is not usable. Select the LED string inside the shaded operating area. Full-power current range 980–1600 mA as listed in the specification; output voltage × current must remain at or below 55 W and inside the I–V boundary. Open-circuit voltage 60 V maximum. Low-frequency current ripple 3.0% maximum at rated current. Current tolerance ±5.0%. Current-setting connection Connect the setting resistor between TB2 pins 7 and 8 (IADJ). The table below lists catalog nominal values. NC means an open setting-resistor connection, which gives 500 mA; it is distinct from the stated factory default. Select the current to match the LED load and its operating voltage. External IADJ resistance → nominal current 18 kΩ 1600 mA 20 kΩ 1520 mA 24 kΩ 1450 mA 27 kΩ 1320 mA 30 kΩ 1260 mA 33 kΩ 1200 mA 36 kΩ 1150 mA 39 kΩ 1110 mA 43 kΩ 1060 mA 47 kΩ 1030 mA 56 kΩ 950 mA 68 kΩ 880 mA 91 kΩ 800 mA 150 kΩ 700 mA 200 kΩ 650 mA NC / open 500 mA Input and electrical performance AC input 180–295 VAC, 47–63 Hz. The current specification publishes no DC input operating range. Input/load derating At 60 Hz, the static-characteristic plot shows 100% load over 180–295 VAC. Temperature and I–V operating limits still apply. Setup time 500 ms at 230 VAC. Measured at the first cold start; switching the supply ON/OFF can increase setup time. Efficiency The shared specification table gives a 90% typical reference at 230 VAC/full load. Note 6 applies a 2% reduction only to the DA type; no separate DA2 correction is stated. Confirm the applicable DA2 efficiency with the manufacturer rather than treating either figure as a DA2-specific guarantee. Power factor Typical PF ≥0.95 at 230 VAC and load ≥50%; PF ≥0.90 at 277 VAC and load ≥75%. Total harmonic distortion THD <10% at load ≥50% on 230 VAC, or load ≥75% on 277 VAC. AC current (typical) 0.35 A at 230 VAC; 0.25 A at 277 VAC. Inrush current (typical) Cold start 30 A at 230 VAC; 300 μs pulse width measured at 50% of peak current, per NEMA 410. Circuit-breaker reference At 230 VAC: up to 17 units on a 16 A type B breaker, or 29 on a 16 A type C breaker. The installation manual bases its matching values on ABB S200 breakers; verify the actual breaker and installation. Leakage current <0.75 mA at 277 VAC. Low-load power Catalog no-load/standby consumption <0.5 W. ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control DA2 suffix: DALI-2 and PUSH dimming, explicitly listed in the model option table. No B-type 3-in-1 DIM interface is specified for this SKU. DA2 documentation boundary The family operating page describes a DALI interface, while the compliance and terminal tables explicitly label DA type. They do not separately define DA2 protocol parts, terminal assignment, low-end step or PUSH timing. Confirm these details for the supplied DA2 hardware with MEAN WELL before connecting or commissioning it. Family DA reference The family DA description gives 16 groups, 64 addresses and an 8% rated-output-power first step; DALI and PUSH cannot operate simultaneously and DA is the default mode. These are DA-family references, not separately confirmed DA2 performance limits. Family PUSH reference The illustrated DA circuit uses a retractive push-to-make button from Ls/DA+ to AC/L, with N/DA− connected to AC/N; a button from Ls to AC/N causes a short circuit. Its DA timing is 0.1–1 s ON/OFF, 1.5–10 s dim/reverse, >11 s reset to 100%; <0.05 s is ignored, with 100% factory dimming. Its stated limit is 10 drivers and 20 m to the last driver. Obtain the DA2-specific wiring/operation confirmation before applying this reference. DALI-2 wiring conditions Verify the actual DALI-2 controller/network and the hardware terminal markings. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), the installation manual requires SELV controllers/networks; consult MEAN WELL for FELV. This is not permission to substitute low-voltage control wiring for mains-referenced PUSH connections. Temperature compensation, protection and environment NTC connection Connect an external temperature-sensing NTC across TB2 pins 5 and 6, with its sensing point on the lighting system or surrounding environment. Without an NTC, the driver runs at the current selected through IADJ. NTC characteristic Below 33 kΩ, output current decreases as NTC resistance decreases; above 33 kΩ, output current remains normal. The table does not specify the exact equality point. MEAN WELL does not supply the NTC; the published values were measured using resistance. Check the temperature curve when selecting a new NTC brand. NTC/control interaction The catalog states that dimming is invalid while temperature compensation is in use. Short-circuit protection Hiccup mode or constant-current limiting; automatic recovery after the fault is removed. Overvoltage protection 61–80 V. Output shutdown with automatic recovery or recovery after re-powering, as stated in the catalog. Overtemperature protection Output shutdown with automatic recovery. Case-temperature range Tcase −25 to +80°C; maximum case temperature +80°C. Measure at the marked tc location in the mechanical drawing. Ambient/load derating Horizontal mounting: 100% load from −25 to +50°C; the plotted points are 80% at +60°C and 60% at +65°C. The ambient curve ends at +65°C. Meet both ambient-load and maximum-case-temperature limits; a case-temperature rating is not an unrestricted ambient rating. Case/load curve The horizontal-mounting case curve remains at 100% through +80°C and ends there. This does not override ambient-temperature derating. Cooling and altitude Free-air convection. Nonstandard mounting or higher ambient temperature may require further current derating. Above 2000 m altitude, reduce the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless driver. Working humidity 20–95% RH, non-condensing. Storage conditions −40 to +80°C; 10–95% RH. Temperature coefficient ±0.03%/°C over 0–60°C. Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis. Performance-plot conditions PF, THD and efficiency plots use Tcase 75°C. THD and efficiency examples use a 1100 mA setting; they do not replace the tabulated typical efficiency or the operating envelope. Lifetime reference Typical life expectancy >50,000 operating hours when Tcase, especially at the marked tc point, is about 70°C or less. Lifetime decreases with increasing case temperature; this is a catalog operating-life reference, not a separate warranty duration. MTBF 2521 K hours minimum, Telcordia SR-332 (Bellcore); 226.1 K hours minimum, MIL-HDBK-217F at 25°C. Mechanical installation and terminals Dimensions 320 × 30 × 21 mm (L × W × H); metal case 258A.

Control terminal confirmation The shared drawing lists pin 5 NC, pin 6 DA−/N and pin 7 DA+/Ls expressly for DA type. It supplies no separate DA2 pin table; confirm the provided DA2 unit’s marking and manufacturer wiring before use. TB2 output and adjustment Pins 1–2 = Vo+; pins 3–4 = Vo−; pins 5–6 = NTC; pins 7–8 = IADJ. Observe LED polarity and do not exceed the selected current/power envelope.

Slim metal housing, active PFC and a catalog flicker-free design with low output-current ripple. Rated output power 55 W maximum within the published constant-power operating envelope. No temporary overload or peak-power rating is specified. Output current region 500–1600 mA; factory default 1050 mA. Preset the rated current with an external resistance across IADJ, rather than a DIP switch. Constant-current voltage region 27–56 V, subject to the current-setting I–V diagram. The low-current corner has a higher minimum voltage; the whole voltage/current rectangle is not usable. Select the LED string inside the shaded operating area. Full-power current range 980–1600 mA as listed in the specification; output voltage × current must remain at or below 55 W and inside the I–V boundary. Open-circuit voltage 60 V maximum. Low-frequency current ripple 3.0% maximum at rated current. Current tolerance ±5.0%. Current-setting connection Connect the setting resistor between TB2 pins 7 and 8 (IADJ). The table below lists catalog nominal values. NC means an open setting-resistor connection, which gives 500 mA; it is distinct from the stated factory default.

The current specification publishes no DC input operating range. Input/load derating At 60 Hz, the static-characteristic plot shows 100% load over 180–295 VAC. Temperature and I–V operating limits still apply. Setup time 500 ms at 230 VAC. Measured at the first cold start; switching the supply ON/OFF can increase setup time. Efficiency The shared specification gives a 90% typical reference at 230 VAC/full load; note 6 states that the DA type is 2% less efficient than that typical value. Power factor Typical PF ≥0.95 at 230 VAC and load ≥50%; PF ≥0.90 at 277 VAC and load ≥75%. Total harmonic distortion THD <10% at load ≥50% on 230 VAC, or load ≥75% on 277 VAC. AC current (typical) 0.35 A at 230 VAC; 0.25 A at 277 VAC. Inrush current (typical) Cold start 30 A at 230 VAC; 300 μs pulse width measured at 50% of peak current, per NEMA 410. Circuit-breaker reference At 230 VAC: up to 17 units on a 16 A type B breaker, or 29 on a 16 A type C breaker. The installation manual bases its matching values on ABB S200 breakers; verify the actual breaker and installation. Leakage current <0.75 mA at 277 VAC. Low-load power Catalog no-load/standby consumption <0.5 W. ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control DA suffix: primary-side DALI interface and PUSH dimming. Do not use DALI and PUSH at the same time; the factory mode is DA. DALI operation Apply the DALI signal between DA+ and DA−. The catalog describes 16 groups and 64 addresses; the first step is fixed at 8% of rated output power. Compliance is stated with IEC 62386-101, -102 and -207 for DA type. DALI/PUSH terminals TB1 pin 6 = DA− / N; pin 7 = DA+ / Ls. These are primary-side control terminals; they are not the B variant’s secondary DIM+/DIM− terminals. PUSH connection Use a retractive push-to-make switch between Ls (DA+) and AC/L; connect N (DA−) to AC/N as shown. Do not connect the pushbutton between Ls and AC/N: the catalog warns this causes a short circuit. PUSH timing Short push 0.1–1 s: ON/OFF. Long push 1.5–10 s: dim up/down, reversing direction with each long push. Reset >11 s: set dimming level to 100%. Actions shorter than 0.05 s do not change status. Factory dimming level: 100%. PUSH system limits Up to 10 drivers can share one pushbutton; maximum cable length from the button to the last driver is 20 m. DALI wiring conditions Confirm DALI controller and network compatibility. For standalone use, dimming conductors smaller than 18 AWG (0.75 mm²) require SELV controllers/networks under the installation manual; seek manufacturer guidance for FELV. This control-network rule does not replace the catalog’s mains-referenced PUSH wiring or its insulation requirements. Temperature compensation, protection and environment NTC connection Connect an external temperature-sensing NTC across TB2 pins 5 and 6, with its sensing point on the lighting system or surrounding environment. Without an NTC, the driver runs at the current selected through IADJ. NTC characteristic Below 33 kΩ, output current decreases as NTC resistance decreases; above 33 kΩ, output current remains normal. The table does not specify the exact equality point. MEAN WELL does not supply the NTC; the published values were measured using resistance. Check the temperature curve when selecting a new NTC brand. NTC/control interaction The catalog states that dimming is invalid while temperature compensation is in use. Short-circuit protection Hiccup mode or constant-current limiting; automatic recovery after the fault is removed. Overvoltage protection 61–80 V. Output shutdown with automatic recovery or recovery after re-powering, as stated in the catalog. Overtemperature protection Output shutdown with automatic recovery. Case-temperature range Tcase −25 to +80°C; maximum case temperature +80°C. Measure at the marked tc location in the mechanical drawing. Ambient/load derating Horizontal mounting: 100% load from −25 to +50°C; the plotted points are 80% at +60°C and 60% at +65°C. The ambient curve ends at +65°C. Meet both ambient-load and maximum-case-temperature limits; a case-temperature rating is not an unrestricted ambient rating. Case/load curve The horizontal-mounting case curve remains at 100% through +80°C and ends there. This does not override ambient-temperature derating. Cooling and altitude Free-air convection. Nonstandard mounting or higher ambient temperature may require further current derating. Above 2000 m altitude, reduce the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless driver. Working humidity 20–95% RH, non-condensing. Storage conditions −40 to +80°C; 10–95% RH. Temperature coefficient ±0.03%/°C over 0–60°C. Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis.

LDC-55B linear LED driver MEAN WELL LDC-55B is a 55 W 3-in-1 dimmable linear LED driver with resistor-selectable constant-current output from 500 to 1600 mA (1050 mA factory default). Match the LED string to the 27–56 V operating envelope and the selected current; the rated power and the catalog I–V boundary must both be respected. Download MEAN WELL LDC-55 Datasheet (PDF)Download MEAN WELL LED Installation Manual SLD/LDC catalog, PDF pages 28–36; LDC-55 specification dated 2026-02-09. The suffix identifies the fitted control interface. Output and current selection Model and function LDC-55B; 3-in-1 dimmable. Slim metal housing, active PFC and a catalog flicker-free design with low output-current ripple. Rated output power 55 W maximum within the published constant-power operating envelope. No temporary overload or peak-power rating is specified. Output current region 500–1600 mA; factory default 1050 mA. Preset the rated current with an external resistance across IADJ, rather than a DIP switch. Constant-current voltage region 27–56 V, subject to the current-setting I–V diagram. The low-current corner has a higher minimum voltage; the whole voltage/current rectangle is not usable. Select the LED string inside the shaded operating area. Full-power current range 980–1600 mA as listed in the specification; output voltage × current must remain at or below 55 W and inside the I–V boundary. Open-circuit voltage 60 V maximum. Low-frequency current ripple 3.0% maximum at rated current. Current tolerance ±5.0%. Current-setting connection Connect the setting resistor between TB2 pins 7 and 8 (IADJ). The table below lists catalog nominal values. NC means an open setting-resistor connection, which gives 500 mA; it is distinct from the stated factory default. Select the current to match the LED load and its operating voltage.

The current specification publishes no DC input operating range. Input/load derating At 60 Hz, the static-characteristic plot shows 100% load over 180–295 VAC. Temperature and I–V operating limits still apply. Setup time 500 ms at 230 VAC. Measured at the first cold start; switching the supply ON/OFF can increase setup time. Efficiency 90% typical at 230 VAC, full load. Power factor Typical PF ≥0.95 at 230 VAC and load ≥50%; PF ≥0.90 at 277 VAC and load ≥75%. Total harmonic distortion THD <10% at load ≥50% on 230 VAC, or load ≥75% on 277 VAC. AC current (typical) 0.35 A at 230 VAC; 0.25 A at 277 VAC. Inrush current (typical) Cold start 30 A at 230 VAC; 300 μs pulse width measured at 50% of peak current, per NEMA 410. Circuit-breaker reference At 230 VAC: up to 17 units on a 16 A type B breaker, or 29 on a 16 A type C breaker. The installation manual bases its matching values on ABB S200 breakers; verify the actual breaker and installation. Leakage current <0.75 mA at 277 VAC. Low-load power Catalog no-load/standby consumption <0.5 W. ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control B suffix: 3-in-1 dimming by 0–10 VDC, a 10 V PWM control signal, or resistance between DIM+ and DIM−. Connect directly to LEDs; additional LED drivers are unsuitable. PWM control frequency 100 Hz–3 kHz for the external 10 V PWM input. This is a control-signal frequency, not a stated LED output PWM frequency. Dimming source current 100 μA typical from the driver. Dimming range Minimum dimming level is about 8%; output current is undefined for 0% < Iout <8%. Output can fall to 0% at about 0 V control input or 0% duty of a 10 V PWM signal. For low-level dimming performance, output current must be over 75 mA. Resistance control The graph gives 10 kΩ/N for 10% and 100 kΩ/N for 100% output current, where N is the number of drivers in synchronized dimming operation. Use the actual characteristic, including its undefined low-level region. DIM terminal restrictions TB2 pin 9 = DIM+; pin 10 = DIM−. Never connect DIM− to Vo−. The LED installation manual identifies the LDC secondary dimming circuit as not isolated from the secondary output. Controller installation Confirm controller compatibility and current capacity. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), the installation manual requires SELV controllers/networks; contact MEAN WELL before using FELV control. The specified TB2 conductors are 0.2–0.5 mm². Temperature compensation, protection and environment NTC connection Connect an external temperature-sensing NTC across TB2 pins 5 and 6, with its sensing point on the lighting system or surrounding environment. Without an NTC, the driver runs at the current selected through IADJ. NTC characteristic Below 33 kΩ, output current decreases as NTC resistance decreases; above 33 kΩ, output current remains normal. The table does not specify the exact equality point. MEAN WELL does not supply the NTC; the published values were measured using resistance. Check the temperature curve when selecting a new NTC brand. NTC/control interaction The catalog states that dimming is invalid while temperature compensation is in use. Short-circuit protection Hiccup mode or constant-current limiting; automatic recovery after the fault is removed. Overvoltage protection 61–80 V. Output shutdown with automatic recovery or recovery after re-powering, as stated in the catalog. Overtemperature protection Output shutdown with automatic recovery. Case-temperature range Tcase −25 to +80°C; maximum case temperature +80°C. Measure at the marked tc location in the mechanical drawing. Ambient/load derating Horizontal mounting: 100% load from −25 to +50°C; the plotted points are 80% at +60°C and 60% at +65°C. The ambient curve ends at +65°C. Meet both ambient-load and maximum-case-temperature limits; a case-temperature rating is not an unrestricted ambient rating. Case/load curve The horizontal-mounting case curve remains at 100% through +80°C and ends there. This does not override ambient-temperature derating. Cooling and altitude Free-air convection. Nonstandard mounting or higher ambient temperature may require further current derating. Above 2000 m altitude, reduce the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless driver. Working humidity 20–95% RH, non-condensing. Storage conditions −40 to +80°C; 10–95% RH. Temperature coefficient ±0.03%/°C over 0–60°C. Vibration 10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes along each X, Y and Z axis. Performance-plot conditions PF, THD and efficiency plots use Tcase 75°C. THD and efficiency examples use a 1100 mA setting; they do not replace the tabulated typical efficiency or the operating envelope. Lifetime reference Typical life expectancy >50,000 operating hours when Tcase, especially at the marked tc point, is about 70°C or less. Lifetime decreases with increasing case temperature; this is a catalog operating-life reference, not a separate warranty duration. MTBF 2521 K hours minimum, Telcordia SR-332 (Bellcore); 226.1 K hours minimum, MIL-HDBK-217F at 25°C. Mechanical installation and terminals Dimensions 320 × 30 × 21 mm (L × W × H); metal case 258A. Mechanical drawing tolerance ±1 mm. Mounting geometry Two Ø4.5 mm end mounting locations, 313 mm center spacing, 3.5 mm from each end; use the exact drawing and allow ventilation. TB1 input terminals Pin 1 = AC/L; pin 2 = AC/N; pin 3 = NC; pin 4 = FG. Connect FG to protective earth. TB2 output and adjustment Pins 1–2 = Vo+; pins 3–4 = Vo−; pins 5–6 = NTC; pins 7–8 = IADJ. Observe LED polarity and do not exceed the selected current/power envelope. TB2 dimming terminals Pin 9 = DIM+; pin 10 = DIM−, for B type only. These do not change the separate IADJ preset-current function. Conductor and strip lengths TB1: 0.5–0.75 mm²; TB2: 0.2–0.5 mm². Strip 8–9 mm for each terminal block. Use approved conductors with adequate current rating and system insulation. Unit mass reference 255 g per unit, converted from the catalog PACKING single-unit reference. This is not a measured shipment or carton weight. Safety, EMC and specification conditions Construction and safety SELV output and Class 2 power-supply design are stated in the catalog. Class 2 does not remove the fitted FG/protective-earth connection requirement.

System wiring and protection Use approved primary and secondary wiring rated for at least the applicable unit current. Provide suitable system-level insulation and an enclosure around single-insulated wiring; verify EMC again in the completed system. Connect a fitted FG terminal to protective earth; the manual exempts only units marked Class II and ungrounded. Environmental and load limits Do not immerse the unit or install it near fire or above its specified ambient limit. Keep output current and power within the model’s rated operating envelope. If a fitted external flexible cable is damaged, replacement is limited to the manufacturer, its service agent or a similarly qualified person. Selection and accessories Choose the complete suffix for the required control interface. The current catalog does not give a dedicated MEAN WELL accessory order code for this driver. External setting resistors, NTC sensors, dimming controllers and pushbuttons must be selected for the actual interface; the NTC is explicitly not supplied by MEAN WELL. Applications Linear lighting and LED fixtures such as office, panel and indoor lighting applications, subject to the fixture design, electrical ratings and thermal conditions.

Low-load power Catalog no-load/standby consumption <0.5 W. ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control DA suffix: primary-side DALI interface and PUSH dimming. Do not use DALI and PUSH at the same time; the factory mode is DA. DALI operation Apply the DALI signal between DA+ and DA−. The catalog describes 16 groups and 64 addresses; the first step is fixed at 8% of rated output power. Compliance is stated with IEC 62386-101, -102 and -207 for DA type. DALI/PUSH terminals TB1 pin 6 = DA− / N; pin 7 = DA+ / Ls. These are primary-side control terminals; they are not the B variant’s secondary DIM+/DIM− terminals. PUSH connection Use a retractive push-to-make switch between Ls (DA+) and AC/L; connect N (DA−) to AC/N as shown. Do not connect the pushbutton between Ls and AC/N: the catalog warns this causes a short circuit. PUSH timing Short push 0.1–1 s: ON/OFF. Long push 1.5–10 s: dim up/down, reversing direction with each long push. Reset >11 s: set dimming level to 100%. Actions shorter than 0.05 s do not change status. Factory dimming level: 100%. PUSH system limits Up to 10 drivers can share one pushbutton; maximum cable length from the button to the last driver is 20 m. DALI wiring conditions Confirm DALI controller and network compatibility. For standalone use, dimming conductors smaller than 18 AWG (0.75 mm²) require SELV controllers/networks under the installation manual; seek manufacturer guidance for FELV. This control-network rule does not replace the catalog’s mains-referenced PUSH wiring or its insulation requirements. Temperature compensation, protection and environment NTC connection Connect an external temperature-sensing NTC across TB2 pins 5 and 6, with its sensing point on the lighting system or surrounding environment. Without an NTC, the driver runs at the current selected through IADJ. NTC characteristic Below 20 kΩ, output current decreases as NTC resistance decreases; above 20 kΩ, output current remains normal. The table does not specify the exact equality point. MEAN WELL does not supply the NTC; the published values were measured using resistance. Check the temperature curve when selecting a new NTC brand. NTC/control interaction The catalog states that dimming is invalid while temperature compensation is in use. Short-circuit protection Hiccup mode or constant-current limiting; automatic recovery after the fault is removed. Overvoltage protection 61–80 V. Output shutdown with automatic recovery or recovery after re-powering, as stated in the catalog. Overtemperature protection Output shutdown with automatic recovery. Case-temperature range Tcase −25 to +80°C; maximum case temperature +80°C. Measure at the marked tc location in the mechanical drawing. Ambient/load derating Horizontal mounting: 100% load from −25 to +50°C; derate to 75% at +60°C and 50% at +70°C. The ambient curve ends at +70°C. Meet both ambient-load and maximum-case-temperature limits; a case-temperature rating is not an unrestricted ambient rating.

LDC-35B linear LED driver MEAN WELL LDC-35B is a 35 W 3-in-1 dimmable linear LED driver with resistor-selectable constant-current output from 300 to 1000 mA (700 mA factory default). Match the LED string to the 27–56 V operating envelope and the selected current; the rated power and the catalog I–V boundary must both be respected. Download MEAN WELL LDC-35 Datasheet (PDF)Download MEAN WELL LED Installation Manual SLD/LDC catalog, PDF pages 19–27; LDC-35 specification dated 2026-02-09. The suffix identifies the fitted control interface. Output and current selection Model and function LDC-35B; 3-in-1 dimmable. Slim metal housing, active PFC and a catalog flicker-free design with low output-current ripple. Rated output power 35 W maximum within the published constant-power operating envelope. No temporary overload or peak-power rating is specified. Output current region 300–1000 mA; factory default 700 mA. Preset the rated current with an external resistance across IADJ, rather than a DIP switch. Constant-current voltage region 27–56 V, subject to the current-setting I–V diagram. The low-current corner has a higher minimum voltage; the whole voltage/current rectangle is not usable. Select the LED string inside the shaded operating area. Full-power current range 625–1000 mA as listed in the specification; output voltage × current must remain at or below 35 W and inside the I–V boundary. Open-circuit voltage 60 V maximum. Low-frequency current ripple 3.0% maximum at rated current. Current tolerance ±5.0%. Current-setting connection Connect the setting resistor between TB2 pins 7 and 8 (IADJ). The table below lists catalog nominal values. NC means an open setting-resistor connection, which gives 300 mA; it is distinct from the stated factory default. Select the current to match the LED load and its operating voltage. External IADJ resistance → nominal current 15.2 kΩ 1000 mA 19 kΩ 900 mA 24.5 kΩ 800 mA 32.5 kΩ 700 mA 43 kΩ 620 mA 46 kΩ 600 mA 72.5 kΩ 500 mA 100 kΩ 450 mA 150 kΩ 400 mA 300 kΩ 350 mA NC / open 300 mA Input and electrical performance AC input 180–295 VAC, 47–63 Hz. The current specification publishes no DC input operating range. Input/load derating At 60 Hz, the static-characteristic plot shows 100% load over 180–295 VAC. Temperature and I–V operating limits still apply. Setup time 500 ms at 230 VAC. Measured at the first cold start; switching the supply ON/OFF can increase setup time. Efficiency 88% typical at 230 VAC, full load. Power factor Typical PF ≥0.95 at 230 VAC and load ≥50%; PF ≥0.92 at 277 VAC and load ≥75%. Total harmonic distortion THD <10% at load ≥50% on 230 VAC, or load ≥75% on 277 VAC. AC current (typical) 0.20 A at 230 VAC; 0.16 A at 277 VAC. Inrush current (typical) Cold start 30 A at 230 VAC; 250 μs pulse width measured at 50% of peak current, per NEMA 410. Circuit-breaker reference At 230 VAC: up to 17 units on a 16 A type B breaker, or 29 on a 16 A type C breaker. The installation manual bases its matching values on ABB S200 breakers; verify the actual breaker and installation. Leakage current <0.75 mA at 277 VAC. Low-load power Catalog no-load/standby consumption <0.5 W. ErP installation condition Use behind a switch; do not leave the LED power supply permanently connected to the mains when meeting the cited ErP lighting-fixture requirements. Control interface Fitted control B suffix: 3-in-1 dimming by 0–10 VDC, a 10 V PWM control signal, or resistance between DIM+ and DIM−. Connect directly to LEDs; additional LED drivers are unsuitable. PWM control frequency 100 Hz–3 kHz for the external 10 V PWM input. This is a control-signal frequency, not a stated LED output PWM frequency. Dimming source current 100 μA typical from the driver. Dimming range Minimum dimming level is about 8%; output current is undefined for 0% < Iout <8%. Output can fall to 0% at about 0 V control input or 0% duty of a 10 V PWM signal. For low-level dimming performance, output current must be over 45 mA. Resistance control The graph gives 10 kΩ/N for 10% and 100 kΩ/N for 100% output current, where N is the number of drivers in synchronized dimming operation. Use the actual characteristic, including its undefined low-level region. DIM terminal restrictions TB2 pin 9 = DIM+; pin 10 = DIM−. Never connect DIM− to Vo−. The LED installation manual identifies the LDC secondary dimming circuit as not isolated from the secondary output. Controller installation Confirm controller compatibility and current capacity. For standalone use with dimming conductors smaller than 18 AWG (0.75 mm²), the installation manual requires SELV controllers/networks; contact MEAN WELL before using FELV control. The specified TB2 conductors are 0.2–0.5 mm². Temperature compensation, protection and environment NTC connection Connect an external temperature-sensing NTC across TB2 pins 5 and 6, with its sensing point on the lighting system or surrounding environment. Without an NTC, the driver runs at the current selected through IADJ. NTC characteristic Below 20 kΩ, output current decreases as NTC resistance decreases; above 20 kΩ, output current remains normal. The table does not specify the exact equality point. MEAN WELL does not supply the NTC; the published values were measured using resistance. Check the temperature curve when selecting a new NTC brand. NTC/control interaction The catalog states that dimming is invalid while temperature compensation is in use. Short-circuit protection Hiccup mode or constant-current limiting; automatic recovery after the fault is removed. Overvoltage protection 61–80 V. Output shutdown with automatic recovery or recovery after re-powering, as stated in the catalog. Overtemperature protection Output shutdown with automatic recovery. Case-temperature range Tcase −25 to +80°C; maximum case temperature +80°C. Measure at the marked tc location in the mechanical drawing. Ambient/load derating Horizontal mounting: 100% load from −25 to +50°C; derate to 75% at +60°C and 50% at +70°C. The ambient curve ends at +70°C. Meet both ambient-load and maximum-case-temperature limits; a case-temperature rating is not an unrestricted ambient rating. Case/load curve The horizontal-mounting case curve remains at 100% through +80°C and ends there. This does not override ambient-temperature derating. Cooling and altitude Free-air convection. Nonstandard mounting or higher ambient temperature may require further current derating. Above 2000 m altitude, reduce the allowed ambient temperature by 3.5°C per additional 1000 m for this fanless driver. Working humidity 20–95% RH, non-condensing.

Factory labels and power limit The listed 4000 mA current default and 48 V voltage default are separate catalog settings; they do not authorize a simultaneous 4 A × 48 V load. Keep the selected operating point within the 151.2 W maximum and the published performance region. Low-input performance region At 120 VAC the shaded diagram marks 1870 mA / 56 V and 2920 mA / 36 V on the reduced-power boundary. Apply the low-input power limit as well as the current adjustment range. Typical efficiency 93% at the catalog test condition. Unless stated otherwise, specifications use 230 VAC input, rated current and 25°C ambient. The performance plots identify a 24 V model at Tcase 75°C.

Overtemperature Output shuts down; reapply power to recover. Protection scope The dedicated constant-power specification lists short-circuit, overvoltage and overtemperature protection. Do not apply the 12/24 V overcurrent threshold or the smaller models’ overpower threshold to this exact model. Operating conditions Parameter Specification Case temperature and cooling Free-air convection. Operating Tcase −25 to +85°C; maximum Tcase +85°C. Case temperature and ambient temperature are different limits. Ambient derating in horizontal mounting At 230 VAC: 100% load from −25 to +40°C ambient, then derate to 50% at +50°C. At 120 VAC: 70% load through +40°C, then derate to 50% at +50°C. Input-voltage derating at 60 Hz The static plot specifies 70% load from 120 VAC to below 200 VAC, and 100% from 200 to 305 VAC. This does not remove the 295 VAC limit below 30 V output on SLD-150-56. Altitude derating For this fanless driver above 2000 m (6500 ft), reduce allowable ambient temperature by 3.5°C per additional 1000 m. Humidity and storage Operating 20–95% RH, non-condensing.
