NShi MS-500W Adjustable Industrial Supply

The NShi MS-500W is an adjustable industrial power supply that converts 110 or 220 VAC input into a variable DC output ranging from 0 to 12 V. It suits engineers and technicians who need a bench-top source for prototyping, testing or powering low-voltage equipment. The unit delivers up to 500 W and is not intended for battery charging applications.

Capacity and headroom at 500 W

At 500 W the supply comfortably runs moderate loads such as LED arrays, DC motors or development boards within the 0-12 V range. Headroom disappears when the combined voltage and current demand reaches the rated limit, so projects requiring higher voltages like 24 V, 48 V or 150 V need a larger model from the series. The 110/220 VAC switching input handles both common mains standards.

Build quality and daily use

A steel desktop chassis measuring 215*115*50 mm houses the circuitry and weighs roughly .9 kg packaged, making it stable on a bench yet portable enough to move between test stations. The adjustable output lets you dial the exact voltage needed without swapping units, while the fixed mains voltage selector simplifies installation in workshops wired for either 110 V or 220 V service.

Questions about this item

Will the MS-500W fit alongside my existing 215 mm wide rack gear?

The chassis measures 215*115*50 mm, matching the width of many 1U shelves, so it should sit flush in the same rack space.

How can I verify the adjustable output is set correctly after wiring?

Use a multimeter on the DC terminals; the supply covers 0-12 V, 15 V, 24 V, 36 V, 48 V, 55 V, 60 V, 72 V, 85 V, 90 V, 110 V, 150 V and 200 V settings.

Does the package include mounting brackets or only the supply itself?

The box contains the MS-500W unit weighing about .9 KG; brackets, rails or cables are not included and must be sourced separately.
