Output and model selection

Parameter Details
Full model NPF-90D-12
Model code NPF identifies the driver family; 90 identifies the nominal series power class; 12 identifies the rated output voltage. Use the actual 90 W rating for this model. D identifies 3-in-1 current dimming.
Output mode Constant current (CC), with 3-in-1 current dimming
Rated output 12 V; 7.5 A; 90 W

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.
Typical efficiency 88%
Startup 500 ms setup at 115 VAC / 230 VAC; measured at first cold start. Repeated switching can increase setup time.

Input and mains loading

Parameter Details
Input range 90-305 VAC / 127-431 VDC; 47-63 Hz
Power factor Built-in active PFC; typical full-load PF ≥0.98 at 115 VAC; ≥0.96 at 230 VAC; ≥0.94 at 277 VAC
Total harmonic distortion THD <20% at load ≥60% with 115/230 VAC, or load ≥75% with 277 VAC
Input current (typical) 0.95 A at 115 VAC; 0.5 A at 230 VAC; 0.4 A at 277 VAC
Cold-start inrush (typical) 60 A at 230 VAC; 550 µs width measured at 50% peak current, per NEMA 410
Maximum units on a 16 A breaker 3 on Type B / 6 on Type C at 230 VAC
Leakage current <0.25 mA at 277 VAC
Standby consumption <0.5 W at 230 VAC
Input/load derating At 60 Hz: 80% load at 90 VAC, rising to 100% at 100 VAC; full-load region through 305 VAC, subject to temperature limits.

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.

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 15-17 V; output shuts down; re-power to recover.
Overtemperature Output shuts down; re-power to recover.
Working case temperature Tcase -40 to +85°C; maximum case temperature +85°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. Ambient Ta curve: 100% load through +50°C, then derate to 50% 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.
Operating humidity 20-95% RH, non-condensing
Storage -40 to +80°C; 10-95% RH
Temperature coefficient ±0.03%/°C over 0 to +50°C
Altitude derating For this fanless design above 2000 m, reduce allowable ambient temperature by 3.5°C per additional 1000 m.
Vibration 10-500 Hz, 5 G, 12 minutes per cycle; 72 minutes along each X, Y and Z axis

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.
