Adjustable DC bench supply

The myVolts MCH-K303D is a switching DC power supply that delivers a continuously adjustable 0-30V output at up to 3A. It suits electronics hobbyists, repair technicians and students who need a stable bench source for prototyping or fault finding.

Compact AT-type chassis with dual-voltage input

The unit uses an AT form factor that keeps the overall footprint small and light while providing full-featured output protection. An input selector lets you run it from 110v or 220v mains at 50/60Hz, so it plugs straight into either supply without extra adapters.

CE-marked 101-200W single-output package

A CE mark confirms compliance with European safety requirements for lab and workshop use. The single regulated output covers a 101-200W power band, giving enough headroom for most phone-repair and low-power circuit tasks without needing a second supply.
