Industrial 24V 500W AC/DC supply

The myVolts RSP-500-24 is an enclosed single-output power supply rated at 500W with a 24V output delivering 21A. It is built for factory automation, test and measurement instruments, laser systems and burn-in facilities that require a rugged AC-to-DC source.

Verify input range and cooling clearance

Confirm the installation site provides 85-264Vac mains and enough airflow for the built-in DC fan that handles forced-air cooling up to 70°C ambient. Ensure the enclosure can accommodate the AT form factor and that wiring allows access to the remote ON-OFF, remote sense and DC OK signal terminals.

Remote control and monitoring built in

The unit integrates active PFC, remote ON-OFF control, remote sense compensation and a DC OK signal so the supply can be managed and monitored directly by the host system. Protection circuits cover short circuit, overload, over voltage and over temperature without extra external components.

Questions about this item

What comes inside the RSP-500-24 box and what must I buy separately?

The package contains the enclosed 500 W 24 V power supply unit only. You will need to source AC input cables, DC output wiring and any mounting hardware separately.

The series lists several output voltages; why choose the 24 V 21 A model?

Select the 24 V version when your equipment requires 24 VDC at up to 21 A. Other models provide 12 V at 41.7 A, 15 V at 33.4 A, 27 V at 18.6 A, 48 V at 10.5 A or lower voltages at higher currents.

What does the 90.5 % efficiency figure mean once the supply is installed in a cabinet?

At full 500 W load the unit converts mains power with up to 90.5 % efficiency, so waste heat is minimised and the built-in fan can maintain operation up to 70 °C ambient.
