Trustpilot

The Sharman LM-40 is a high-quality linear power supply designed for amateur radio, communications, and test bench use. Delivering a maximum output of 40 amps, it features variable voltage control (adjustable from approximately 9v to 15v DC), making it ideal for powering HF, VHF, UHF transceivers, and other demanding 12v DC equipment.

  • Maximum Current Output: 40 Amps

  • Type: Linear power supply (low noise)

  • An analogue voltmeter and ammeter are on the front panel
