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.

1. A device for controlling a power distribution to subsystems, comprising 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 means for sensing when a current level falls below a threshold in response to the primary device being turned off and when the current level raises above a threshold in response to the primary device being turned on; and executing means operatively connected with said sensing means and operative for interrupting a power supply to said at least one secondary device when the sensing means sense the current level below the threshold and supplying power to said at least one secondary device when said sensing means 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, said voltage limiting means including a gate element connected parallel with said sensing means, said voltage limiting means including means for ensuring that said sensing means first acts on said executing means, and only thereafter said gate element limits the voltage of said sensing means.
