Industrial 800W DC Power Supply

This NShi unit converts AC mains between 185 and 264 volts into selectable DC outputs of 12, 24, 36 or 48 volts at up to 800 watts. It is built for engineers and system integrators who need a compact, fan-cooled supply for test benches, automation cabinets or custom server chassis.

Input range and protection limits

The wide AC input spans 185 to 264 volts with leakage below 0.7 milliamps at 230 volts. Output voltage can be trimmed by ±10 percent while load regulation stays within ±0.5 percent. Over-current trips at 110 to 130 percent and over-voltage at 115 to 150 percent, with short-circuit protection built in.

Desktop chassis with forced-air cooling

The 260 by 110 by 70 millimetre enclosure fits a standard desktop footprint and uses an internal fan for thermal management. Installation requires wiring to screw terminals and confirming the selected output voltage before power-on; incorrect voltage selection or reversed polarity are the most common errors. Not suited for builders who need redundant hot-swap modules or ATX-form-factor connectors.

Questions about this item

Which output voltage should I select — 12V, 24V, 36V or 48V?

Choose the voltage that matches your load; the unit delivers 12V, 24V, 36V or 48V DC and the output can be trimmed by ±10% to suit the exact requirement.

What does the 800W rating mean when the supply is installed in a server chassis?

It can provide up to 800W continuous DC power with fan cooling, full-load aging tested, and hold-up time of 20ms at full load.

What AC input standard does the supply accept and what does that limit in practice?

It accepts 185–264VAC (tested at 230VAC with <0.7mA leakage), so it operates on standard single-phase mains worldwide without additional conditioning.
