Frequently Asked Questions
Is the NPF-120-12 suitable for outdoor LED lighting applications?
Yes. The NPF-120-12 carries an IP67 rating, meaning it is fully protected against dust ingress and temporary water immersion. Its operating temperature range of -40°C to +90°C makes it suitable for exposed outdoor environments as well as unheated enclosures.
What industrial or embedded applications is the NPF-120-12 designed for?
The NPF-120-12 outputs 12V DC at up to 10A (120W), which suits 12V LED strip systems, machine vision lighting, industrial control panels, and embedded computing systems that accept 12V input. Its Class II isolated plastic case eliminates the need for a protective earth connection, simplifying integration in plastic enclosures.
How does the NPF-120-12 compare to the other NPF-120 voltage variants?
All NPF-120 non-dimming variants share the same 120W power class, IP67 rating, 191.0 × 63.0 × 37.5 mm footprint, and 0.97 kg weight. Output current decreases as voltage increases: 12V/10A, 15V/8A, 20V/6A, 24V/5A, 30V/4A, 36V/3.4A (122.4W), 42V/2.9A (121.8W), 48V/2.5A, 54V/2.3A (124.2W). Choose the voltage that matches your LED load's rated voltage.
Does the NPF-120-12 require a protective earth ground connection?
No. The NPF-120-12 uses a Class II design without a functional ground (FG) terminal. The fully isolated plastic case provides double insulation, so no chassis ground connection is required for safe operation.
What is the constant-current voltage range of the NPF-120-12?
The NPF-120-12 operates in constant-current mode across a CC voltage range of 7–12V. Within this range the driver regulates output current at 10A regardless of load voltage, which protects LED strings from overcurrent during warm-up or dim conditions.
