Sharman SM30SWX Switch Mode Power Supply 30A Continuous, 5-15V Adjustable DC

The Sharman SM30SWX is a robust, switch-mode regulated DC power supply delivering 30A continuously over 8 hours — making it an ideal bench power supply for CB radios, amateur radio transceivers, and other 12V DC equipment. With an adjustable output voltage of 5–15V DC, it covers a wide range of equipment requirements. Built-in over-current protection activates automatically at 33.5A (±0.5A), and the ultra-low ripple voltage of just 5mV RMS ensures clean, stable power with no interference to sensitive radio equipment. Cooled by an inbuilt fan and protected by a T5A fuse. Accepts UK mains input of AC 220–240V (50Hz).
