Output and model selection

Parameter Details
Full model NPF-120D-15BE
Model code NPF identifies the driver family; 120 identifies the nominal series power class; 15 identifies the rated output voltage. Use the actual 120 W rating for this model. D identifies 3-in-1 current dimming. BE identifies the auxiliary DC output option, listed by the manufacturer as a by-request configuration.
Output mode Constant current (CC), with 3-in-1 current dimming
Rated output 15 V; 8 A; 120 W
Constant-current region 9-15 V

Output performance

Parameter Details
Current tolerance ±5.0%
Current ripple 5.0% maximum at rated current
LED driving method Direct connection to compatible LEDs is recommended. This constant-current dimming driver is not suitable for use with additional LED drivers. The highest voltage in the CC region depends on the final system configuration; verify load compatibility.
Auxiliary DC output Nominal 12 V, deviation 11.4-12.6 V at 0.2 A; AUX+ to DIM−. Use yellow AUX+ and pink DIM−; this reference is not Vo−.
Typical efficiency 87.5%; BE value measured with the auxiliary output fully loaded at 12 V, 0.2 A
Startup 500 ms setup at 115 VAC / 230 VAC; measured at first cold start. Repeated switching can increase setup time.

Total harmonic distortion THD <20% at load ≥60% with 115/230 VAC, or load ≥75% with 277 VAC
Input current (typical) 1.3 A at 115 VAC; 0.65 A at 230 VAC; 0.55 A at 277 VAC
Cold-start inrush (typical) 60 A at 230 VAC; 520 µs width measured at 50% peak current, per NEMA 410

Dimming interface

Parameter Details
Control connection Apply one control method between purple DIM+ and pink DIM−. Do not connect DIM− to black Vo−.
Accepted controls 0-10 VDC, or 10 V PWM at 100 Hz-3 kHz, or resistance
Dimming source current 100 µA typical from each driver
Controlled output Output constant-current level
Minimum level and off command Minimum dimming level is about 6% of rated output current; output current between 0% and 6% is undefined. Current can fall to 0% with about 0 kΩ, 0 VDC, or a 10 V PWM signal at 0% duty.
Full-output reference 10 VDC, 100% duty 10 V PWM, or 100 kΩ/N resistance, where N is the number of drivers in synchronized dimming. Select a controller for the combined source current and follow the complete control curve.
Control isolation The NPF dimming circuit is not isolated from the secondary output. Maintain the insulation and isolation required by the complete system.
SELV controller requirement These dimming leads are smaller than 18 AWG (0.75 mm²). The manufacturer permits only SELV dimming controllers for standalone supplies with these leads; consult MEAN WELL before using a FELV controller.

Protection and operating environment

Parameter Details
Overcurrent 95-108% of rated current; constant-current limiting; automatic recovery after the fault is removed.
Short circuit Hiccup mode; automatic recovery after the fault is removed.
Overvoltage 17.5-21 V; output shuts down; re-power to recover.
Overtemperature Output shuts down; re-power to recover.
Working case temperature Tcase -40 to +90°C; maximum case temperature +90°C. These are case limits, not full-load ambient ratings.
Cooling and ambient derating Free-air convection with the recommended horizontal mounting. The following ambient and case-temperature limits apply to horizontal installation as shown in the mechanical drawing. For this 12/15 V branch, ambient Ta curve: 100% load through +40°C, then derate to 40% at +70°C. The -40 to -25°C region is specified only for 230 VAC input. Meet both the ambient-load curve and the maximum case temperature.

Installation and service Disconnect the utility supply before installation or maintenance and prevent accidental reconnection. Keep the unit ventilated and free of stacked objects; leave 10-15 cm from an adjacent heat source. Derate for nonstandard mounting orientation or excessive ambient temperature. Use approved cables with current ratings at least equal to the unit rating; check all connections. Keep single-insulated wires covered by the final system enclosure. Do not open the case; damaged external cables must be replaced by the manufacturer, service agent or similarly qualified personnel.

Final equipment The driver is a component. The final equipment manufacturer must re-qualify EMC for the complete installation; component approvals do not automatically certify the finished luminaire.
Type HL application The catalog lists Type HL use in Class I, Division 2 hazardous (classified) locations; the finished installation must satisfy the applicable luminaire and location requirements.
Manufacturer lighting-installation condition For the lighting-fixture ErP condition stated in the datasheet, install behind a switch, without a permanent connection to the mains.
BE application restriction The manufacturer specifies BE for light sources exempt from the EU 2019/2020 requirement, such as road, railway, marine or air-traffic signalling, traffic control or airfield lamps. Confirm the intended light-source application before selection.
