Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing:
[0017] Such as figure 1 As shown, the control circuit with dual DC power input in this embodiment includes a logic control circuit unit 1 , a first opening control circuit 2 and a second opening control circuit 3 .
[0018] The logic control circuit unit 1 samples the input conditions of the DC power supply and performs logic analysis, and controls the first opening control circuit 2 and the second opening control circuit 3 with the generated control signal. The input situation of the power supply is sampled and logically analyzed, and the generated control signal is controlled by the second opening control circuit 3. The first opening control circuit 2 performs the opening and closing functions according to the signal of the logic control circuit unit 1. The second The second turn-on control circuit 3 performs turn-on and turn-off functions according to the signal of the ...
