The Extech 382276 600W Switching Mode DC Power Supply (230V) delivers stable bench power for labs, service bays, and production lines. It regulates clean output under changing loads and keeps performance reliable across long sessions.

Precision and control

You set voltage and current with confidence, then check them at a glance on twin LED readouts. Two user presets and a fixed 13.8V setting speed up repeat tasks and reduce setup error.

Cooling and protection

A thermostatic fan manages airflow as demand rises, helping maintain quiet, efficient operation. Built-in over-voltage, over-temperature, and short-circuit protection guard your work and connected devices.

This switching design offers high immunity to radio-frequency interference with excellent EMI performance for sensitive benches. It operates from a 220V, 50/60Hz mains supply and keeps ripple low so measurements stay consistent and trustworthy.

Key features
  • Variable output for a wide range of DC tasks
  • High current capability for demanding loads
  • Twin LED readouts improve quick checks
  • User presets enable fast repeat setups
  • Fixed 13.8V option streamlines mobile installs
  • Strong immunity to radio interference
  • Low ripple output supports sensitive circuits
  • Thermostatic fan aids efficient cooling
  • Integrated protection enhances equipment safety
  • Switching design saves bench space and weight
  • Clear controls support straightforward operation
