MEAN WELL NPF & LPF Series LED Power Supplies
Series Overview & Comparison
The NPF and LPF series are highly reliable, fully encapsulated LED drivers featuring dual-mode Constant Voltage + Constant Current (CV+CC) outputs. While they share a similar rugged, flame-retardant plastic housing (IP67, Class II), they are optimized for slightly different applications.
- NPF Series (Flicker-Free): Premium drivers engineered specifically to eliminate light flickering. They feature extremely low standby power consumption (<0.15W) and are favored for high-end indoor, residential, and architectural lighting where visual comfort is paramount.
- LPF Series (Standard Highly Reliable): The foundational series offering robust environmental protection and up to 91% efficiency. It provides exceptional flexibility for a vast range of general outdoor and indoor LED applications.
- Dual Mode Operation: Both series output a fixed voltage up to their maximum rated current, seamlessly transitioning into a constant current source to safely drive bare LEDs.

Dimming Options & Application Guide
Both series are available in standard (non-dimmable) and dimmable variants to accommodate diverse lighting control systems.
| Model Suffix | Dimming Feature | Best Usage & Controls |
|---|---|---|
|
Blank (e.g., NPF-90-24, LPF-60-24) |
Non-dimmable | Standard fixed lighting, ON/OFF switching setups, outdoor decorative lighting, and commercial signage. |
|
D or V (e.g., NPF-90D-24, LPF-60D-24) |
3-in-1 Dimming | Supports 0~10VDC, PWM signal, or resistance dimming. Ideal for smart home integration, automated building systems, and tunable architectural lighting. |
Choose NPF for indoor residential lighting, office LED panels, downlights, and poultry/agricultural lighting where a flicker-free environment is critical for health and visual comfort.
Choose LPF for harsh environments, street lighting, high-bay lighting, greenhouse setups, and general damp/wet locations where robust environmental protection is the primary concern.
