Sharman SM30SWI 20A Switch Mode Power Supply 13.8V DC, 30A Peak

The Sharman SM30SWI is a compact switch-mode DC power supply designed for amateur radio, CB radio and other compatible 13.8V communications equipment. It provides a fixed 13.8V DC output with up to 20A continuous current and 30A peak current.

An illuminated analogue meter can display either voltage or current, while the front-panel Noise Offset control can be adjusted to help move switching noise away from the operating frequency. A front accessory socket provides a convenient output for compatible 12V equipment up to 10A.
