REDARC In-Vehicle Battery Chargers are DC power supplies that provide regulated power for sensitive load requirements, including lamps, radios, communications equipment, pumps, TVs, and more from an automotive power system. The versatile chargers are available in 12 and 24 V units, with 10, 20, 25, or 40 amp output. These power supplies offer a wide input voltage range and optional voltage output for higher efficiency and improved functionality. Without a fan, the noise level is reduced and enables the unit to power hi-tech radio systems without interference. Encapsulated by REDARC's silicone elastomer, the power supplies can be easily mounted on the outside of the vehicle and used in marine situations. There is also built-in protection against surges and spikes.
