Abstract
The present disclosure relates to a solid state power controller, comprising: a power switch for interrupting a line; a current sensor for measuring a current flow on the line; and a control unit for controlling the power switch and that is configured to prevent a time-dependent overcurrent on the line on the basis of the current measured by the current sensor, wherein the control unit comprises a counter that is adapted to increment a count when the measured current is larger than a threshold value and to decrement the count when the measured current is smaller than the threshold value; and wherein the power switch is adapted to interrupt the line when the counter reaches or exceeds a predefined count.
