Power lock device safe power source output/input

摘要

A power lock device for safe power output/input is a control lock composed of coding devices, decoding devices and electromagnetic switches. The coded signal will attach to the power transmitting line and keeps on transmitting. After discerning that the coded signal is correct, the decoding device turns on electromagnetic switches and conducts power to transmit. If the code is not correct, the decoding device uses the electromagnetic switches to cut off power and achieves the function of power control.
