SEC America Model 364 DC Converter

24 VDC to 13.8 VDC at 50 amps continuous

The SEC America Model 364 DC Converter is a US built 600 watt unit, of the highest quality. The SEC unit is highly efficient, which provides cool operation, high reliability, and long life expectancy for the converter and the equipment which it powers. The design makes this performance possible over an extremely wide operating temperature range(the best we have seen) and under the most rigorous vibration and shock conditions. Only top quality components are used and the circuit boards are fully potted. These units may cost more than others, but are fully suitable for military, industrial, scientific, and other applications where exceptional electronics are demanded.
