480W 24V 20A Power Supply

The NShi SDR-480-24 is a DIN-rail switching power supply delivering 480 watts at 24 volts with a 20 amp output. It is built for industrial control cabinets and server chassis requiring reliable AC-DC conversion in a compact form factor. High efficiency reaches 94 percent, reducing heat and energy waste. Certifications include UL, CUL, TUV, CE, GL and SEMI F47 for demanding environments.

Suited for Space-Constrained Industrial Builds

This unit fits installers who need high power density on a standard DIN rail without exceeding narrow width allowances. The thin profile saves valuable cabinet space compared to bulkier alternatives. Buyers who require a different output voltage or a lower total wattage should look at other models in the SDR series. It is not intended for consumer PC cases lacking DIN-rail mounting provisions.

94 Percent Efficiency Rating

The headline specification is the 94 percent conversion efficiency, which directly determines thermal load and operating cost in continuous-duty applications. This figure confirms the supply meets the SEMI F47 voltage-sag immunity standard required by semiconductor tools. Verify that your system draws no more than 20 amps at 24 volts to stay within the rated 480 watt limit.

Questions about this item

Will the 94 % efficiency rating hold up after years of continuous 24 V 20 A operation?

The unit is rated for 94 % efficiency at full load; efficiency typically remains stable over the service life if the supply is kept within its thermal limits and not subjected to sustained overloads.

What is the first limit reached when the SDR-480-24 runs at 480 W continuously?

At 480 W output the supply delivers its maximum 20 A current; thermal protection will activate before any electrical limit is exceeded, so sustained full-power operation requires adequate airflow around the chassis.

How much fan noise and heat should I expect from the SDR-480-24 in a closed rack all day?

The supply has no internal fan; it relies on convection cooling, so acoustic noise is negligible, but the 6 % losses at 480 W become heat that must be ventilated from the enclosure to avoid thermal shutdown.
