Adjustable AC-DC switching supply delivers 0-100 V output with LED readout in a 0.44 lb desktop chassis
The NShi switching power supply delivers a single adjustable output from 12 V up to 100 V with a 1500 W rating. It is built for bench testing, prototype work and lab equipment that need variable DC voltage from an AC source. The desktop chassis weighs .44 pounds and fits on a standard work surface.
The unit runs from a 380 V AC input and uses switching topology to maintain efficiency across the 1000 W to 2000 W range. Fan speed ramps with load so noise stays low during typical 1500 W operation. No liquid cooling or external radiator is required.

Mount the unit in the desktop chassis using its built-in screw holes, then connect the AC input to mains and the DC output to your load; the step people get wrong is reversing the positive and negative output terminals, which will prevent the adjustable 0-100V display from showing correct voltage.
The fan intake should be cleared of dust every few months to maintain airflow through the 0.44-pound chassis; if the adjustable output drifts or the LED display fails, the entire 1500W unit must be replaced as no internal modules are user-serviceable.
