  • Publication number: 20220238287
    Abstract: Disclosed is a dual-input circuit, adopting a contactor as a switching device, and being more suitable for medium and high-power applications. In addition, the adopted contactor is a single double-pole double-throw contactor with an interlocking function. In this way, the circuit is safe, simple, and easily controllable, and space utilization can be further improved. In addition, the adopted contactor further is of a magnetic attraction type, with lower power consumption for long-term work. In the present invention, either one of two inputs is set as a main input and the other is set to a backup input by default, so that the present invention can be more flexibly applied and is more applicable. To enable switching when both or only either one of the two inputs has an input voltage, the present invention further adopts a single dual-input auxiliary power supply to reduce a required space and further reduce costs.
