myVolts AC-DC Switching Power Supply 12V 20A 250W

SKU CH-7QR0-W4HS9

Converts AC mains to 12 V DC at 20 A with built-in over-voltage, over-current and short-circuit protection

  • TypeAT
  • Converts mains AC to stable 12 V DC for reliable equipment power
  • Delivers up to 20 A continuous current for demanding 12 V loads
  • Built-in over-voltage, over-current and short-circuit protection safeguards connected devices
  • Metal enclosure aids heat dissipation for consistent operation
  • Certified to CCC, RoHS and CE standards for safety compliance

12 V 20 A switching supply

This AC-to-DC unit converts 110 V or 220 V mains to a regulated 12 V output rated at 20 A and 250 W. It is built for indoor bench work, test rigs and fixed installations that need a stable 12 V rail. The metal enclosure meets CCC, RoHS and CE marks.

250 W continuous headroom

At full load the supply delivers 20 A continuously while built-in over-voltage, over-current and short-circuit protection guard the output. It operates from 0 °C to 40 °C with humidity up to 95 % non-condensing. Loads above 20 A or sustained ambient temperatures over 40 °C are outside the rated envelope.

AT form-factor compatibility

The supply follows the AT type designation and measures 200 mm by 100 mm by 44 mm with an input range of 110 V or 220 V ± 15 %. Builders using ATX-only mounting holes or needing a different form factor cannot use this unit.

Perguntas sobre este artigo

Will the 20 A 12 V output run alongside my older 12 V 10 A supply on the same 110 V/220 V circuit?

Both units accept 110 V/220 V AC input, so they can share the same mains circuit. The 20 A model is rated for 250 W and the 10 A model for 120 W.

How can I verify the 250 W unit is delivering a stable 12 V after installation?

Measure the DC output terminals with a multimeter; a reading near 12 V under load confirms the built-in over-voltage, over-current and short-circuit protection is functioning.

Does the package include mounting brackets or a power cord, or must I buy them separately?

The box contains only the power supply unit. Mounting hardware and an AC input cord are not included and must be sourced separately.
