Frequently Asked Questions
What dimming inputs does the NPF-90D-20 accept?
The NPF-90D-20 integrates 3-in-1 dimming, accepting PWM signal, 0–10V analog, and resistance control, all built in without external dimming accessories.
Is the NPF-90D-20 a good match for dimmable 20V LED panels in a medical imaging facility?
The NPF-90D-20 delivers 90W at 20V with a constant current of 4.5A and built-in dimming, making it suitable for medical imaging or examination room LED panels that require stable, adjustable illumination. Its UL and CE certifications support use in regulated medical facility environments.
How does the NPF-90D-20 differ from the NPF-60D-20?
Both are dimmable 20V IP67 drivers with 3-in-1 dimming, but differ in power: NPF-60D-20 is 60W at 3A (150.0 × 53.0 × 35.0 mm, 0.49 kg), while NPF-90D-20 is 90W at 4.5A (171.0 × 63.0 × 37.5 mm, 0.77 kg). Select based on the LED load’s total wattage.
Can the NPF-90D-20 operate in an outdoor carport or canopy structure exposed to rain?
Yes. The NPF-90D-20 is IP67-rated and operates from -40°C to +85°C, making it appropriate for outdoor carport or canopy LED lighting in wet conditions.
Does the NPF-90D-20 require a ground connection?
No. The NPF-90D-20 uses a Class II fully isolated plastic case without a functional ground (FG) terminal, so no protective earth wiring is required.
