Abstract
A device for controlling a power distribution to subsystems which has a power input to be connected to a power source, a primary power output to be connected to a primary device, at least one secondary power output to be connected to at least one secondary device; sensing unit for sensing when a current level falls below a threshold in response to the primary device being turned off and when the level current raises above a threshold in response to the primary device being turned on; and executing unit operatively connected with the sensing unit and operative for interrupting a power supply to the at least one secondary device when the sensing unit sense the current level below the threshold and supplying power to the at least one secondary device when the sensing unit sense the current level above the threshold correspondingly; and means for limiting voltage across said sensing means so as to limit heat produced by said sensing means but at the same time to allow tripping of said sensing means.
