  • Ultra-low no-load draw below 0.5 W
  • Leakage current under 220 µA for patient safety

Medical-grade power supply

The NShi RPS-500-36-C is a 500.4W server chassis power supply delivering 36V at 13.9A. It carries medical safety approvals to ANSI/AAMI ES60601-1 and IEC/BS EN/EN60601-1 with 2×MOPP rating. The desktop form factor fits standard server deployments requiring patient-contact equipment compliance. Builders working on BF-rated medical systems will find the leakage current below 220uA.

Input range and efficiency limits

The unit accepts 80–264VAC input and reaches up to 94% efficiency across the operating range. No-load consumption stays under .5W via PS_ON control. Protections cover short circuit, overload, over voltage and over temperature. EMC compliance meets BS EN/EN55011 for both Class I and Class II configurations. Operating temperature spans –30 to +70°C.

Upgrade from non-medical supplies

This supply replaces standard industrial units when 2×MOPP isolation and sub-220uA leakage are mandatory for patient-contact applications. The jump is worth it for equipment that must meet EN60601-1 and EN55011 without external filtering. It is not for builds that only need basic SELV output or can tolerate higher leakage current. Non-medical server deployments gain no regulatory advantage.

Questions about this item

What does the 500.4W rating mean for a server build?

The unit can deliver up to 500.4W continuously, so a system drawing less than that at 36V will run within the supply's rated capacity.

How does the 94% efficiency affect heat and power draw?

At 94% efficiency only about 6% of input power becomes heat, reducing cooling needs and lowering electricity use compared with less efficient units.

What does the 80–264VAC input range allow in practice?

The supply accepts mains voltages from 80V to 264V, so it works worldwide without a voltage selector switch.
