Medical-Grade Server Power Supply

The NShi RPS-500-18-C is a 500.4 W desktop server chassis power supply delivering 18 V at 27.8 A. It carries 2×MOPP medical safety approval to ANSI/AAMI ES60601-1 and IEC/BS EN/EN60601-1. Efficiency reaches 94 % and no-load draw stays below 0.5 W under PS_ON control.

Suited For Regulated Medical Builds

This unit fits engineers integrating BF-rated patient-contact equipment that requires Class I or Class II EMI compliance to EN55011. Builders needing other output voltages, higher continuous power, or non-medical industrial certifications should look at alternative series.

500.4 W Continuous With Wide Temperature Headroom

The supply maintains full rated output across a -30 °C to +70 °C operating range and accepts 80–264 V AC input. Leakage current remains under 220 µA. Over-voltage, overload, short-circuit and over-temperature protections shut down the unit before components are stressed beyond safe limits.

Questions about this item

What input voltage range must my facility provide for this 500.4 W medical power supply to operate?

The unit accepts 80 to 264 VAC, so any standard mains supply within that window will power it.

Can I install this chassis in a system that uses a Class II design without a protective earth connection?

Yes, the blank-type RPS-500 is approved for both Class I with FG and Class II without FG configurations.

How can I verify the supply is running efficiently after installation?

Measure the output under load; the efficiency reaches up to 94 percent and no-load draw stays below 0.5 W when PS_ON is active.
