Industrial 500 W 12 V power supply

The myVolts RSP-500-12 is a 500 W single-output enclosed AC/DC unit that delivers 12 V at 41.7 A. It is built for factory automation, test and measurement instruments, laser equipment and burn-in facilities that need a reliable 12 V rail.

Forced-air cooling with 90.5 % efficiency

A built-in DC fan provides forced-air cooling up to 70 °C ambient. High efficiency up to 90.5 % and active PFC keep input current low across the 85-264 Vac range, reducing heat and noise in normal operation.

Remote control and protection features

Remote ON/OFF, remote sense and a DC OK signal simplify integration into control cabinets and automated lines. Short-circuit, overload, over-voltage and over-temperature protections guard connected equipment.

Questions about this item

How do I mount the RSP-500-12 and connect the AC input, and what is the common wiring mistake?

Mount the enclosed unit on a flat surface with screws through its four corner holes, then wire the AC terminals to a 85-264Vac supply; the frequent error is reversing live and neutral on the input block.

Which component will need replacement first during continuous operation?

The built-in DC fan is the only moving part and will wear out before the solid-state circuitry under sustained load.

At what ambient temperature does the 12V 41.7A output start to derate?

The unit is rated for full 500W output up to 70°C; above that temperature the protection circuitry reduces power to prevent overheating.
