myVolts DC 12V Switching Power Supply 25-350W

SKU CH-PDAA-1CVRW

A switching power supply delivers regulated 12 V DC at 25 W to 350 W with overload, overvoltage and short-circuit protection for industrial, LED and 3D-printing applications

  • Product typeAT
  • Reliable power for diverse equipment with 12 V DC output from 25 W to 350 W
  • Safe operation backed by 100 % full-load burn-in and short-circuit, overload, overvoltage protection
  • Efficient switching design delivers low DC ripple for stable performance across industrial, LED, CCTV and 3D-printing uses
  • Durable aluminium-alloy chassis rated for 0 °C to 40 °C operation and -20 °C to 60 °C storage
  • Certified to CCC, FCC and CE standards with high insulation strength for dependable long-term service

Industrial DC 12V Power Supply

This myVolts switching power supply delivers regulated DC 12V output with an adjustable range spanning 25W to 350W. It targets engineers and technicians powering LED strips, CCTV rigs, 3D printers and similar industrial automation equipment.

Upgrade from linear or unregulated units

Replace older linear transformers or basic unregulated adapters when efficiency and low DC ripple matter. The jump is worth it for continuous-duty loads that demand stable voltage and built-in overload, overvoltage and short-circuit protection.

Sustained-load behaviour

After a 100% total-load burn test the unit maintains output across a working temperature range of 0 to 40 Celsius. Aluminium alloy construction aids heat dissipation while high insulation strength supports reliable long-term operation.
