Frequently Asked Questions
What is the actual measured output power of the NPF-120-36?
The NPF-120-36 is rated at 122.4W — slightly above 120W — because at 36V and 3.4A the product of voltage and current equals 122.4W. This is the rated maximum continuous output under normal operating conditions.
Can the NPF-120-36 be installed outdoors without an additional enclosure?
Yes. The NPF-120-36 carries an IP67 rating, indicating it is sealed against dust and temporary immersion. Its -40°C to +90°C operating temperature supports outdoor use across most climate zones. No additional weatherproof enclosure is required, though protecting the cabling connections from moisture remains good practice.
What types of 36V LED applications is the NPF-120-36 suited for?
The NPF-120-36 provides 36V DC at 3.4A (122.4W) in constant-current mode, with a CC voltage range of 21–36V. It suits mid-voltage LED modules used in commercial downlights, horticultural grow lights, and architectural linear fixtures that are designed around a 36V constant-current source. Its universal 90–305VAC input makes it deployable on any global mains circuit.
How does the NPF-120-36 compare to the NPF-120-42 and NPF-120-48?
All three share IP67 protection and the 191.0 × 63.0 × 37.5 mm footprint (0.97 kg). NPF-120-36 outputs 36V at 3.4A (122.4W, CC range 21–36V); NPF-120-42 outputs 42V at 2.9A (121.8W, CC range 25–42V); NPF-120-48 outputs 48V at 2.5A (120W, CC range 28–48V). Each targets a different mid-to-high-voltage LED string length.
