Industrial 500W 12V Supply

The myVolts XC-500-12 is a switched-mode power supply that converts AC 110V or 220V input to a regulated DC 12V output at 42A. It delivers 500W continuous power from an aluminium enclosure measuring 241mm by 123mm by 65mm. The unit includes short-circuit, overload, over-voltage and over-temperature protection plus a built-in EMI filter for low ripple and noise. It is FCC, CE and RoHS compliant and has passed 100% full-load burn-in testing.

Suits LED and Automation Builds

This supply suits installers powering LED strips, CCTV systems, industrial automation gear or office equipment that require a steady 12V rail at high current. The three positive and three negative output terminals simplify parallel wiring for large lighting runs. Builders needing a standard ATX form factor for a PC, multiple voltage rails, modular cabling or a silent fanless design for a living-room HTPC should look elsewhere.

500W Headroom at 40°C

At 42A the unit provides 500W with headroom for typical LED arrays and control electronics operating in ambient temperatures up to 40°C. The output voltage can be trimmed by approximately 13% via the ADJ terminal to compensate for cable drop. Continuous operation at full load demands good airflow; in poorly ventilated enclosures the over-temperature protection will trigger and shut the output down until the unit cools.

Questions about this item

Do I need to set the voltage selector switch to 110V or 220V before connecting it to my mains supply?

The unit ships with the side switch set to 110V/115V for US use. Move the selector to the 220V/230V position if your mains voltage is 220V or 230V before powering on.

Can I run this 12V 42A supply alongside an older 12V 10A unit on the same LED strip installation?

Parallel or redundancy operation is supported. Both supplies must be set to the same output voltage using the ADJ trimmer so current shares evenly across the +V and -V terminals.

How can I confirm the output is delivering the rated 12V 42A after wiring it up?

Measure across the +V and COM terminals with a multimeter under load. The ADJ trimmer allows a 13% adjustment range so you can set the exact voltage your equipment requires.
