SEC America Model 680 DC Converter

12 VDC to 25.2 VDC at 40 amps continuous

The SEC America Model 680 DC Converter is a US built 960 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. We have multiple units of this model on armored vehicles in the Middle East.
