Industrial 500W enclosed supply

The myVolts RSP-500-27 is a 500W single-output enclosed AC/DC power supply that delivers 27V at 18.6A. It accepts a universal 85-264Vac input and includes active PFC for improved power factor. The unit is built for factory automation, test instruments, laser equipment and burn-in facilities.

Sustained-load behaviour

High efficiency up to 90.5% reduces waste heat during continuous operation. Forced air cooling from the built-in DC fan maintains thermal stability up to 70°C ambient. Protections for short circuit, overload, over voltage and over temperature engage automatically under prolonged stress.

Installation practicalities

Enclosed chassis simplifies mounting in control cabinets or power distribution systems. Remote ON-OFF control, remote sense and DC OK signal terminals support system integration without extra wiring. The 3-year warranty covers defects, but the unit is not suited for builds needing ATX connectors or multiple output rails.

Questions about this item

How much acoustic noise and heat does the built-in DC fan produce when the RSP-500-27 runs continuously at 500W?

The unit uses forced-air cooling with a built-in DC fan that adjusts speed with temperature, allowing operation up to 70°C ambient while maintaining up to 90.5% efficiency to limit waste heat.

What wiring and mains connection must I provide for the screw-terminal AC input and 27V DC output?

You need suitably rated cable, crimp lugs or ferrules for the screw terminals, and a mains lead rated for 85–264VAC to connect the supply to your distribution panel.

Can the remote ON-OFF, remote sense and DC OK signals interface directly with 24V PLC logic and older relay panels?

Yes — the built-in remote ON-OFF control, remote sense and DC OK signal are designed for industrial control cabinets and work with standard 24V logic and relay-based systems.
