A programmable desktop DC supply delivering 0–60 V at up to 5 A with four-digit 0.01 V / 0.001 A readout and automatic constant-voltage/constant-current crossover
The NShi WPS605H is a programmable DC power supply delivering up to 60V and 5A with a four-digit display showing 0.01V and 0.001A resolution. It suits electronics hobbyists, students, and repair technicians who need precise, adjustable voltage and current for bench work.
Unlike fixed-voltage wall adapters or basic unregulated supplies, this unit lets you set exact voltage and current limits with fine and coarse adjustment. The jump is worth it when you need constant-voltage and constant-current modes that switch automatically, plus built-in OVP, OCP, OTP and overload protection with audible alarms.
A temperature-controlled fan keeps the chassis cool during extended sessions, so output remains stable over long test runs rather than drifting after a short burst. Dual AC input (110V and 220V) lets you move the supply between lab benches without reconfiguring the mains connection.
Measured against everything we stock in Rackmount Server Cases, at today’s prices. Recalculated every night.

The desktop chassis is compact and lightweight so it fits on a standard bench or shelf without special mounting hardware.
Use the coarse and fine knobs to adjust output from 0 to 60 V and 0 to 5 A; the four-digit display shows 0.01 V and 0.001 A resolution. Remember to select the correct AC input (110 V or 220 V) before powering on.
The temperature-controlled fan is the main wear item; keep its intake clear so the over-temperature protection does not trip and the unit runs quietly.
