CRT SPS-30E Switched Mode Power Supply 13.8V / 25-30A, USB Port, LCD Display, Noise Filter, 110/230V

The CRT SPS-30E is a compact, lightweight switched-mode power supply delivering 13.8V DC at 25A continuous / 30A peak — ideal for powering CB radios, amateur radio transceivers, and other 12V radio equipment from the mains. Unlike traditional linear power supplies, the switched-mode design keeps weight down to just 1.65kg while maintaining clean, stable output. The SPS-30E includes several features that set it apart from basic power supplies: a built-in USB charging port (2A) for charging devices, a dual LCD display showing output voltage and current simultaneously, a Noise Off-Set function, and rejector filters to minimise RF interference — important for radio use where a noisy PSU can degrade receiver performance. Output voltage is fixed at 13.8V DC or adjustable between 9–15V DC. Switchable between 110V and 230V AC input for international use.
