Industrial AC/DC Power Supply

The myVolts RSP-500-48 is a 500W single-output enclosed power supply delivering 48V at 10.5A. It targets engineers and technicians building factory automation, test instruments, laser systems or burn-in rigs that need a rugged AC/DC source with active PFC and remote monitoring.

Replacing Linear or Older Switching Units

The jump is worth it when a project demands universal 85-264Vac input, up to 90.5% efficiency and built-in protections such as short-circuit, overload, over-voltage and over-temperature in one enclosed chassis. It is not for designs that require multiple output voltages or battery-backed operation.

Installation and Common Issues

Mount the unit in a ventilated enclosure, connect AC input and DC output terminals, then wire the remote ON-OFF, remote sense and DC OK signals if the control system uses them. The built-in DC fan handles forced-air cooling up to 70°C ambient; the main failure mode is blocked airflow or wiring the sense leads incorrectly, which can shut the supply down.

Questions about this item

What mounting holes or brackets does the RSP-500-48 use to fit in a control cabinet?

The RSP-500-48 is an enclosed unit designed for panel or chassis mounting inside control cabinets and power distribution systems.

How do I wire the remote ON-OFF and DC OK signals during installation, and what mistake should I avoid?

Connect the remote ON-OFF and DC OK terminals to your control circuit; the common error is leaving the remote sense lines floating instead of tying them to the output terminals.

Which component will need replacement first in a 24/7 laser cutting system, and what is its rated life?

The built-in DC fan provides forced air cooling up to 70°C ambient; it is the only moving part and will require replacement before the 3-year warranty period ends.
