Frequently Asked Questions
Is the NPF-120-20 rated for outdoor or wet-location use?
Yes. The IP67 rating on the NPF-120-20 means it is sealed against dust and can withstand temporary immersion in water. Combined with its -40°C to +90°C operating temperature range, it is suitable for outdoor signage, facade lighting, and other exposed installations.
What LED applications suit the NPF-120-20's 20V output?
The NPF-120-20 supplies 20V DC at 6A (120W). It is a practical choice for 20V-rated LED modules used in architectural accent lighting, retail display fixtures, and mid-voltage LED strip systems designed to run at 20V. The constant-current output protects LEDs from thermal runaway.
How does the NPF-120-20 compare to its 120W siblings at 24V and 30V?
All three share IP67 protection, the 191.0 × 63.0 × 37.5 mm housing, and 0.97 kg weight. The NPF-120-20 outputs 20V at 6A (CC range 12–20V); the NPF-120-24 outputs 24V at 5A (CC range 14–24V); the NPF-120-30 outputs 30V at 4A (CC range 18–30V). Each is suited to LED loads rated at its respective voltage.
Does the NPF-120-20 support universal mains input?
Yes. The NPF-120-20 accepts 90–305VAC, covering both 120VAC (North America) and 230VAC (Europe/Asia) mains voltages without any manual voltage switching. This simplifies global product procurement and reduces the number of SKUs needed for multi-region deployments.
