Frequently Asked Questions
Is the NPF-120-54 suitable for outdoor LED driver applications?
Yes. The NPF-120-54 is IP67 rated, offering complete dust protection and resistance to temporary immersion. With an operating temperature range of -40°C to +90°C, it can be mounted inside outdoor fixtures, landscape lighting enclosures, or exposed industrial environments without further weatherproofing of the driver itself.
What LED applications is the NPF-120-54 designed for at 54V?
The NPF-120-54 outputs 54V DC at 2.3A (124.2W) in constant-current mode with a CC range of 32–54V. It suits high-voltage LED strings in commercial street lights, horticultural grow fixtures, industrial high-bay luminaires, and outdoor floodlights that specify a 54V constant-current supply.
How does the NPF-120-54 differ from the NPF-120D-54?
Both deliver 54V at 2.3A (124.2W) with IP67 protection and identical physical dimensions (191.0 × 63.0 × 37.5 mm, 0.97 kg). The NPF-120D-54 adds built-in 3-in-1 dimming (PWM, 1–10V, and resistance), while the NPF-120-54 has no dimming input. Use the NPF-120D-54 where remote brightness adjustment is needed; the NPF-120-54 for fixed-output installations.
What input voltage range does the NPF-120-54 support?
The NPF-120-54 accepts 90–305VAC, covering standard 120VAC North American mains, 230VAC European mains, and higher industrial supply voltages up to 305VAC. No manual voltage selection or external transformer is required for operation on any of these supplies.
