Frequently Asked Questions
What dimming methods does the NPF-90D-48 support?
The NPF-90D-48 includes built-in 3-in-1 dimming that accepts PWM signal, 0–10V analog, and resistance control, all natively integrated without requiring an external dimmer.
Is the NPF-90D-48 suitable for driving dimmable 48V LED modules in outdoor tunnel lighting?
The NPF-90D-48 delivers 90.24W at 48V with a constant current of 1.88A and a CC voltage range of 28–48V, which covers many 48V LED tunnel or underpass lighting modules. Its IP67 rating and -40°C to +85°C range suit the damp, variable-temperature conditions inside road tunnels.
How does the NPF-90D-48 compare to the NPF-90D-54 and the NPF-60D-48?
NPF-60D-48 is a dimmable 48V, 60W, 1.25A driver in a 150.0 × 53.0 × 35.0 mm body. NPF-90D-48 is the 90W, 1.88A version at 171.0 × 63.0 × 37.5 mm. NPF-90D-54 is the higher-voltage sibling at 54V and 1.67A with the same 90W power and body size as the NPF-90D-48.
Can the NPF-90D-48 be used outdoors in a freeze-thaw climate without additional weatherproofing?
Yes. With IP67 waterproof protection and a -40°C to +85°C operating range, the NPF-90D-48 handles outdoor freeze-thaw cycles and precipitation without a secondary enclosure.
What certifications apply to the NPF-90D-48?
The NPF-90D-48 holds CB, CCC, CE, EAC, ENEC, and UL certifications and comes with a 5-year manufacturer warranty.
