Abstract
Disclosed is a DC adaptor for driving a magnetic contactor including at least: an AC input terminal; a capacitor connected to the AC input terminal; an electronic switch connected to the capacitor in parallel; a full-wave rectifier which converts an AC current into a DC current; a DC output connecting line which receives the DC current from the full-wave rectifier to transmit the DC current to the magnetic contactor; a sensing unit which measures a current value of a driving coil of the magnetic contactor; a controller which compares the measured current value with a reference value to output an on/off control signal of the electronic switch; a DC power source which generates a DC power using the DC current converted by the full-wave rectifier; and a housing which accommodates the above elements.
