NShi Server Chassis 30V 5A WPS305H

SKU CH-4HFH-1R2AR

A programmable DC power supply with 30 V, 5 A output, four-digit 0.01 V and 0.001 A readout, and OVP, OCP, over-temperature and short-circuit protection

  • Chassis TypeDesktop
  • Precise voltage control with 0.01 V display resolution
  • Accurate current setting via 0.001 A readout
  • Automatic protection stops output on short circuit
  • Adjustable 0–30 V and 0–5 A output ranges
  • Dual AC input accepts 110 V and 220 V

Programmable DC Power Supply 30V 5A

This programmable DC power supply delivers adjustable output up to 30 volts and 5 amps for bench and lab use. A four-digit display shows voltage to 0.01 V and current to 0.001 A. It suits technicians, students and repair shops needing precise, low-noise power for circuits and devices.

Input Voltage and Bench Space

Verify that your mains supply is either 110 V or 220 V AC, as the unit accepts both. Confirm you have a desktop area for the compact chassis and that the temperature-controlled fan can draw ambient air without obstruction. No rack mounting hardware is included.

Sustained Load Behaviour

Under continuous operation the supply maintains constant voltage or constant current with automatic crossover. Over-voltage, over-current, over-temperature and short-circuit protections shut down output and sound an alarm when limits are exceeded. The temperature-controlled fan keeps noise low during extended sessions.

Questions about this item

Does the WPS305H unit ship with everything needed to operate it, or are extra leads required?

The WPS305H is a bench-top programmable DC power supply with a four-digit display showing 0.01 V and 0.001 A resolution. It accepts dual AC input of 110 V or 220 V and provides continuously adjustable output from 0 to 30 V and 0 to 5 A.

The supplier lists several models such as WPS3010H and WPS605H; which one matches a 30 V 5 A requirement?

Model WPS305H is the 30 V 5 A version. Other listed models are WPS1602H at 160 V 2 A, WPS1203H at 120 V 3 A, WPS3010H at 30 V 10 A and WPS605H at 60 V 5 A.

What does the 30 V 5 A rating mean when the supply is connected to a real load?

You can set any voltage between 0 and 30 V and any current limit between 0 and 5 A with fine and coarse adjustment. The unit automatically switches between constant-voltage and constant-current modes and includes OVP, OCP, over-temperature and short-circuit protection with alarm.
