Model, output and control

Parameter	Specification
Model	PWM-120-24
Series and function code	PWM-120; blank suffix: 3-in-1 dimming
Output mode	Constant voltage with PWM-style output; dimming varies output-current duty cycle. Built-in active power factor correction (PFC).
DC output voltage	24 V
Rated output current	5 A
Rated output power	120 W
Output PWM frequency	1.47 kHz, fixed typical output waveform frequency.
Dimming interface	0–10 VDC, additive 10 V PWM at 100 Hz–3 kHz, or resistance between DIM+ and DIM−
Dimming range	Catalog range 0–100%. Approximate minimum output duty 0.15% at 0.6 VDC, 6 kΩ (one driver), or 6% duty of the external 10 V PWM signal; lower input can dim the output to 0%.
Dimming source and synchronization	100 μA typical source current. Resistance scaling: 100 kΩ / N at full output, where N is the number of synchronized drivers. Do not connect DIM− to the negative LED output. Use a controller with capacity of at least 0.15 mA per PWM driver, as required by the installation instructions.

Input frequency	47–63 Hz
Typical efficiency	90% at the catalog test conditions
Typical power factor	>0.97 / 115 VAC; >0.96 / 230 VAC; >0.93 / 277 VAC at full load; PF changes with load.
THD	<20% at ≥60% load / 115 or 230 VAC, or ≥75% / 277 VAC; consult the model-specific load curves.
Typical AC input current	1.3 A / 115 VAC; 0.65 A / 230 VAC; 0.55 A / 277 VAC
Inrush current	Cold start: 60 A typical at 230 VAC; 520 μs pulse width measured at 50% peak, per NEMA 410.
Circuit-breaker reference	4 / 6 units for type B / type C 16 A breakers at 230 VAC, respectively. Catalog reference only; verify the actual breaker and system conditions.
Leakage current	<0.25 mA at 277 VAC
No-load or standby power	<0.5 W no-load consumption.
Setup and rise time	500 ms setup, 80 ms rise / 115 or 230 VAC. Cold-start measurement; rapid switching may increase setup time.
Hold-up time	16 ms / 115 or 230 VAC typical

Protection and operating conditions

Parameter	Specification
Overload protection	108–130% of rated output; Hiccup mode; automatic recovery after the fault is removed.
Short-circuit protection	Hiccup mode; automatic recovery after the fault is removed.
Overvoltage protection	28–34 V; Output shuts down; remove the fault, then re-power to recover.
Overtemperature protection	Output shuts down; remove the fault, then re-power to recover.
Working case temperature	−40 to +90°C; maximum case temperature +90°C, subject to derating.
Cooling and load derating	Free-air convection with recommended horizontal mounting. 100% through +45°C ambient, falling to 50% at +70°C. The −40°C to −25°C region is for 230 VAC input only. Keep Tc at or below +90°C; apply both ambient and input limits.
Input/load derating	At 60 Hz: 80% at 90 VAC, rising to 100% at 100 VAC; 100% through 305 VAC.
Humidity and storage	Working: 20–95% RH, non-condensing. Storage: −40 to +80°C, 10–95% RH.
Temperature coefficient	±0.03%/°C over 0–45°C
Altitude derating	Above 2000 m, reduce the allowable ambient temperature by 3.5°C per additional 1000 m for this fanless design.
Vibration	10–500 Hz, 5 G, 12 minutes per cycle, 72 minutes along each X/Y/Z axis.

BIS IS15885 (Part 2/Sec13) is listed for this model/version.
EMC	Emission: BS EN/EN55015, BS EN/EN61000-3-2 Class C at ≥60% load, BS EN/EN61000-3-3, GB/T17743, GB17625.1 and EAC TP TC 020.

Dimensions and installation

Parameter	Specification
Dimensions	191 × 63 × 37.5 mm (L × W × H); plastic housing.
Lead connections	Input: AC/L brown, AC/N blue. LED output: +V red, −V black. Control: DIM+ purple, DIM− pink. Do not connect DIM− to negative LED output.
Cable specification	Input: SJTW 18 AWG × 2C; LED output: SJTW 14 AWG × 2C. Control: UL2464 18 AWG × 2C. Lead runs: 300 ±20 mm; refer to the mechanical drawing for breakout lengths.
Mounting	Use the model-specific drawing; 4.5 mm mounting holes. Maintain recommended horizontal mounting and keep the marked Tc point below the case-temperature limit.
Ingress protection	Fully encapsulated IP67, for dry, damp or wet locations subject to the installation instructions. Suitable indoors or outdoors without direct sunlight; do not immerse or operate the product in water. Seal system interconnections and any waterproof connector against water ingress.
Installation	Disconnect the supply before installation or maintenance and prevent inadvertent reconnection. Keep ventilation clear, do not stack objects on the unit, and leave 10–15 cm clearance when the adjacent device is a heat source. Approved primary/secondary cables must carry at least the unit’s rated current. Nonstandard mounting or high ambient temperature requires derating. Confirm controller compatibility; the catalog calls for 0.15 mA controller capacity per PWM driver. Insulate system interconnections and enclose single-insulated wires; do not dismantle the driver. Damaged external cables must be replaced by the manufacturer, its service agent or an equally qualified person.
Dimming isolation	Treat the analog dimming circuit as not isolated from the secondary output, as specified in the LED installation manual; provide appropriate system insulation.
Weight	970 g; catalog packing reference per unit (0.97 kg × 1000), not a measured net or shipping parcel weight.
Service-life reference	Typical lifetime >50,000 hours when the marked Tc/TMP point is about +75°C or below. Manufacturer catalog warranty: 5 years, subject to MEAN WELL’s warranty statement; not an additional store promise.

Unless stated otherwise, catalog parameters are measured at 230 VAC input, rated current and +25°C ambient. Typical figures and load curves apply only to their stated conditions. Read the linked drawings and installation instructions before system design.
