myVolts AT Switching Power Supply 12V 25A 300W

SKU CH-J5CT-J22XC

Converts AC mains input to 12 V DC at up to 25 A and 300 W with built-in over-voltage, over-current and short-circuit protection

  • Product typeAT
  • Delivers stable 12 V DC at 25 A for 300 W output
  • Wide AC input range from 110 V to 240 V suits global mains
  • Metal enclosure aids heat dissipation and protects internal components
  • Built-in over-voltage, over-current and short-circuit protection safeguards connected equipment
  • Certified to CCC, RoHS and CE standards for safety compliance

AC 220V industrial switching supply

The myVolts AT switching power supply converts AC 220V input to a regulated 12V DC output rated at 25A and 300W. It is built for indoor installations that need a fixed-voltage rail for LED strips, CCTV systems, CNC accessories or similar 12V loads. The metal enclosure meets CCC, RoHS and CE compliance for commercial environments.

25A continuous at 12V decides fit

The single specification that determines suitability is the 25A continuous current rating at 12V, delivering 300W. Systems drawing less than 25A will operate within spec; loads that exceed this value require a higher-capacity unit. Input range covers AC 110V to 240V so the same model works on global mains without rewiring.

Convection-cooled metal case runs silent

A fanless aluminium chassis dissipates heat passively across its full surface area, so acoustic output is zero in normal use. Over-voltage, over-current and short-circuit protection circuits engage automatically during fault conditions. The supply is rated for continuous operation between 0°C and 40°C ambient with humidity up to 95% non-condensing.
