100W IP67 power supply for LED lighting with 142V 700mA output and active PFC
The NShi Server Chassis houses a 100W single-output switching supply rated at 142V and 700mA. It accepts a wide 180 to 528VAC input range and delivers up to 91.5% efficiency with active PFC built in. The unit suits LED lighting and street lighting installations in dry, damp or wet locations.
An IP67 and IP65 rated enclosure protects the electronics for indoor or outdoor mounting without extra weatherproofing. Cooling relies on free air convection so no fan noise or moving parts are introduced. Output current can be trimmed through the output cable or an internal potentiometer for precise setup.
This chassis replaces open-frame or lower-rated units that cannot withstand moisture or wide voltage swings. The jump is worth it when installations demand IP67 protection, active PFC and adjustable constant current in a single desktop form factor. It is not for builders who need multiple independent outputs or a rackmount footprint.
Measured against everything we stock in Rackmount Server Cases, at today’s prices. Recalculated every night.

The unit operates from 180 VAC to 528 VAC, so it covers a wide industrial and street-lighting supply window.
It is rated IP67 and IP65, making it suitable for dry, damp and wet locations without additional enclosures.
Use the built-in 3-in-1 dimming interface — 0–10 VDC, PWM signal or external resistance — to adjust the constant-current level without opening the case.
