Frequently Asked Questions
Is the NPF-120-42 suitable for use in humid or wet industrial environments?
Yes. The NPF-120-42 has an IP67 ingress protection rating, meaning it is fully sealed against dust and can withstand temporary submersion in water. Its operating temperature spans -40°C to +90°C, covering both hot industrial environments and cold outdoor sites.
What LED driver applications match the NPF-120-42's 42V output?
The NPF-120-42 delivers 42V DC at 2.9A (121.8W) in constant-current mode with a CC range of 25–42V. It is appropriate for high-bay LED fixtures, outdoor wall-pack luminaires, and street lighting modules that specify a 42V LED string. The 90–305VAC input makes it usable across international mains voltages.
How does the NPF-120-42 compare to the NPF-120-36 and NPF-120-48?
All three share the IP67 rating, 191.0 × 63.0 × 37.5 mm housing, and 0.97 kg weight. NPF-120-36 is 122.4W at 36V/3.4A (CC range 21–36V); NPF-120-42 is 121.8W at 42V/2.9A (CC range 25–42V); NPF-120-48 is 120W at 48V/2.5A (CC range 28–48V). The differences are strictly in output voltage, current, and CC range.
Does the NPF-120-42 carry UL certification?
Yes. The NPF-120-42 is certified to UL standards, along with CB, CCC, CE, EAC, and ENEC. UL certification is typically required for luminaire integration in North American commercial and industrial projects, and these marks together satisfy requirements across major global markets.
