NShi WPS3010H Programmable Supply

The NShi WPS3010H is a programmable DC bench power supply built for laboratory work, repair benches and classroom experiments. It delivers adjustable voltage and current with fine and coarse controls for precise setup. Safety protections include over-voltage, over-current, over-temperature and overload shutdown with an audible alarm. Dual AC input accepts 110 V and 220 V mains without selector switches.

30 V 10 A Four-Digit Resolution

The single specification that decides fit is the 30 V 10 A output range shown on a four-digit display with 0.01 V and 0.001 A resolution. This combination covers low-voltage logic rails, phone repair rails and general prototype rails in one unit. If your project needs more than 30 V or more than 10 A this model cannot meet the requirement.

Temperature-Controlled Fan Cooling

A temperature-controlled fan spins only as fast as needed so acoustic noise stays low during long sessions. Constant-voltage and constant-current modes switch automatically when limits are reached, keeping the output stable without manual intervention. The compact desktop chassis fits on crowded benches while the high power density maintains rated output continuously.

Questions about this item

What does the 30 V 10 A rating mean when the unit is powering a real circuit?

The supply can deliver any voltage from 0 to 30 V and any current from 0 to 10 A, automatically switching between constant-voltage and constant-current modes so the output stays at the set limits.

What interface does the WPS3010H use for mains input and what voltage range does it accept?

It has a dual-voltage AC inlet that works with both 110 V and 220 V mains without any manual switching.

What physical space and mounting does the desktop chassis need?

The unit is a compact desktop chassis designed to sit on a bench; its small footprint and light weight let it fit in limited lab or repair-space without rack mounting.
