Output and selection

Parameter Specification
Identity and model code SLD-150-56: SLD family, 150 W class, 56 V model code. Constant-power mode with adjustable current. The family wattage label is not a substitute for the exact rating.
Rated output power 151.2 W; input-voltage and thermal derating apply.
Rated output current 4000 mA factory default; maximum rated output power remains 151.2 W.
Output voltage region 24–56 V in constant-current operation. The catalog separately lists a factory default of 48 V.
Adjustment and full-power ranges Current adjustment 1400–4170 mA using the built-in Io adjustment. Full-power current range 2680–4170 mA. Voltage, current and power maxima are not independently combinable.
Open-circuit voltage 60 V maximum.
Current ripple and tolerance 5.0% ripple at rated current; current tolerance ±5%.
Recommended performance region The catalog outlines these boundary points: 1400 mA / 56 V; 2680 mA / 56 V; 4170 mA / 36 V; 4170 mA / 24 V; 2680 mA / 24 V. Select within the shaded I–V region and respect the power limit; boundary values are published graph values.
Startup 500 ms at 230 VAC. First cold start; repeated ON/OFF can increase setup time.
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.

Input supply

Parameter Specification
Input supply 120–305 VAC; 170–431 VDC; 47–63 Hz AC. Built-in active PFC.
Power factor PF ≥0.95 at 230 VAC; ≥0.92 at 277 VAC, at full load.
Total harmonic distortion THD <10% at load ≥60% / 230 VAC or load ≥75% / 277 VAC.
Typical AC current 1 A / 230 VAC; 0.8 A / 277 VAC.
Typical inrush and circuit-breaker reference 65 A; width 500 μs at cold start, 230 VAC, width measured at 50% Ipeak, per NEMA 410. At 230 VAC on a 16 A circuit breaker: 5 type B / 8 type C units maximum in the catalog reference.
Leakage current <0.35 mA at 294 VAC.
Low-output-voltage input limit For output voltage below 30 V, maximum AC input is 295 VAC, as required by the model-specific note.

Protection and recovery

Parameter Specification
Short circuit Hiccup mode; automatic recovery after the fault is removed.
Overvoltage 60–70 V; output shuts down; reapply power to recover.
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. Storage −40 to +80°C.
Temperature coefficient ±0.03%/°C over 0–60°C.
Vibration 10–500 Hz, 2 G, 12 minutes/cycle; 72 minutes on each X, Y and Z axis.
MTBF 2883.5 / 298.8 thousand hours minimum: Telcordia SR-332 / MIL-HDBK-217F at 25°C, respectively.
Service life and warranty Typical life expectancy 50,000 hours when the designated tc/TMP point is about 75°C or lower. The graph shows life decreasing as case temperature increases; it is not a guaranteed replacement interval. Manufacturer warranty 5 years, subject to applicable manufacturer terms.

Safety and installation qualifications

Parameter Specification
Construction and classification Plastic slim linear housing, Class II design. No Class 2 claim is made for this 150 W model.
Safety standards ENEC BS EN/EN61347-1 and -2-13 independent; BS EN/EN62384; EN60335-1; EAC TP TC 004; GB/T19510.1 and GB/T19510.213; BIS IS15885 (Part 2/Sec 13), as listed in the dedicated specification.
Electrical insulation Input–output withstand 3.86 kVAC. Input–output insulation resistance 100 MΩ at 500 VDC, 25°C and 70% RH.
EMC emissions Conducted and radiated: BS EN/EN55015 (CISPR15) / EN55014; GB/T17743. Harmonic current: BS EN/EN61000-3-2 and GB17625.1, Class C at load ≥60%. Voltage flicker: BS EN/EN61000-3-3.
EMC immunity BS EN/EN61547. ESD: Level 3, 8 kV air; Level 2, 4 kV contact. Radiated, EFT/burst, conducted and magnetic-field tests: Level 2. Surge: 1 kV line-to-line. Applicable test series: BS EN/EN61000-4-2, -3, -4, -5, -6, -8 and -11.
Voltage dips and interruptions >95% dip for 0.5 periods; 30% dip for 25 periods; >95% interruptions for 250 periods.
Complete-installation responsibility This driver is a component of the final equipment; requalify EMC on the complete installation. Catalog RCM/Non-IC independent-controlgear note states it is unsuitable for residential installations and recommends commercial decoration, signage or luminaire applications. Apply that installation qualification rather than treating a general application example as approval.
Switching condition The catalog requires installation behind a switch, without permanent mains connection, to meet its stated lighting-fixture ErP condition.

Dimensions, connection and installation

Parameter Specification
Dimensions and mounting 330 × 35 × 22 mm (L × W × H); drawing tolerance ±1 mm. Two Ø3.5 mm mounting holes; the drawing gives 322 × 27 mm mounting-reference dimensions. Use the complete drawing for placement.
Designated case measuring point The top-view tc point is located by 124 mm and 15 mm reference dimensions in the drawing. Measure the designated point in the final installation.
Input terminals TB1: pin 1 AC/L, pin 2 AC/N. DEGSON DG202-5.0 gray terminal.
Output terminals TB100: pin 1 +V, pin 2 −V. DEGSON DG202-5.0 red/black terminal.
Wiring dimensions Input and output conductor area 0.75–2.50 mm²; strip length 9–10 mm, per the mechanical drawing.
Adjustment and ordering scope The 56 V model has the built-in Io adjustment shown beside the output terminal. This is not a B/DA remote-dimming suffix.
Unit weight reference 310 g, converted from the explicit single-unit PACKING mass. This is the catalog packing reference, not a measured net or shipping weight.
Carton reference 48 units / 15.9 kg / 0.79 cu.ft. The unit weight is not calculated by dividing the carton mass.
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.
