Abstract
A method and apparatus is provided for controlling power to a DC load ON and OFF. The apparatus has a first FET bank, a second FET bank, connected in series with a first FET bank, and a controller. The controller is configured for detecting a operational failure of at least one of the FET banks, and turning at least on of the FET banks OFF in response, thereby turning power to the DC load OFF. The controller may also detect a operational failure of one of the FET banks, and turn the other FET bank OFF in response, thereby turning power to the DC load OFF.
