Industrial 500W 15V Power Supply

The myVolts RSP-500-15 is a 500W single-output enclosed AC/DC power supply delivering 15V at 33.4A. It suits factory automation control apparatus, test and measurement instruments, laser-related machines and burn-in facilities. The unit accepts a universal 85-264Vac input with built-in active PFC function for industrial environments.

Forced-Air Cooling 90.5% Efficiency

Forced air cooling by a built-in DC fan manages thermals during normal operation. High efficiency up to 90.5% reduces waste heat and power draw across the input range. Protections include short circuit, overload, over voltage and over temperature to maintain stable output.

Sustained Load Remote Monitoring

Remote ON-OFF control, remote sense and DC OK signal allow integration into automated factories and power distribution cabinets for continuous duty. The supply operates at ambient temperatures up to 70°C with fan speed control adapting to sustained loads. Three-year warranty covers industrial use cycles.

Questions about this item

How do I mount and wire the RSP-500-15, and which step causes the most trouble?

Screw the enclosed chassis to a flat metal surface using the four corner holes, then connect live, neutral and earth to the three‑pin input block; the step most installers miss is tightening the DC output terminals to the specified torque so the 33.4 A load cannot loosen them.

What part will need replacement first during continuous operation?

The built‑in DC cooling fan is the only moving component; after several years of 24/7 use at up to 70 °C ambient its bearings wear out and the fan must be swapped to keep forced‑air cooling effective.

At what point does the unit hit its limit under sustained full load?

The 500 W / 15 V output is capped at 33.4 A; if the draw exceeds that, overload protection activates and shuts the supply down until the load drops back within the rated current.
