ABSTRACT:
A power supply equipped with an independent overload protection mechanism includes a control circuit and a transformation circuit that form multiple sets of combination circuits for transforming AC power to DC power. Each control circuit is connected to a protection circuit which monitors overload operation conditions of an electronic device. In the event that an overload condition occurs, the protection circuit outputs an individual protection signal to the control circuit to stop or suspend power output on a DC power cord so that the electronic device at the rear end is not driven. Hence an independent overload protection can be achieved.
