Wide-range alternating current contactor control device

The utility model discloses a wide-range alternating current contactor control device. The wide-range alternating current contactor control device comprises a wide-range direct current source, an alternating current contactor, a power supply circuit, a master control circuit, a Boost boosting circuit, and a protection circuit, the input voltage of the wide-range direct current source is alternating current 85 V-270 V, the output voltage is 24 V, the input voltage outputs the 24 V direct current voltage respectively to the power supply circuit and the Boost boosting circuit via the wide-range direct current source, the 24 V direct current is processed to 17 V in the manner of voltage reduction via the power supply and is supplied to the master control circuit for pulse width modulation, pulse signals are outputted to control the Boost boosting circuit to boost to the alternating current contactor for absorption, and the signals are fed back to the master control circuit by the Boost boosting circuit to determine whether boosting is normally realized. When the Boost boosting circuit is boosted to 316 V, the protection circuit reduces the voltage to 5 V via the processing of the power supply circuit, the wide-range direct current source outputs the 24 V direct current via the Boost boosting circuit, and continuous absorption of the alternating current contactor is maintained.
