Industrial 500 W Adjustable Supply

The NShi MS-500W is a desktop-format industrial power supply that converts 110 VAC or 220 VAC mains into an adjustable 0–30 VDC output. It targets engineers, technicians and system integrators who need a bench-top or chassis-mounted DC source for prototyping, test rigs or embedded equipment.

Check Input Voltage Setting

Before wiring the unit, confirm the mains selector matches your local supply of 110 VAC or 220 VAC. Verify that the load you intend to drive stays within the 500 W rating and the 0–30 VDC adjustment range, and ensure the desktop enclosure has adequate ventilation in the intended mounting position.

Compact Enclosure With Screw Terminals

The chassis measures 215 mm by 115 mm by 50 mm and weighs approximately 0.9 kg, allowing it to sit on a bench or be bolted inside a cabinet. Screw-terminal blocks on the front provide secure connections for both AC input and DC output, reducing the risk of loose leads during vibration or repeated reconfiguration.

Questions about this item

Does the MS-500W ship with mounting hardware or only the supply itself?

The unit measures 215*115*50mm and weighs about .9KG; mounting brackets or rails are not included.

Should I pick the MS-500W or a higher-wattage model such as the MS-1000W?

The MS-500W delivers 500W from 110/220VAC switching input; the MS-1000W provides 1000W but requires a fixed 110VAC or 220VAC input and measures 240*125*65mm at 1.65KG.

What does the 0-30VDC rating mean when the supply is powering a real load?

The output voltage can be adjusted anywhere between 0 and 30VDC, so the supply will maintain whatever voltage the connected equipment requires up to the 500W limit.
