Patent attributes
An over-voltage protection circuit assembly includes a connector and an over-voltage protection circuit. The connector includes a power terminal. The over-voltage protection circuit includes a voltage input terminal, and a voltage output terminal. The voltage output terminal connected to the voltage input terminal via a resistor. A relay includes an inductance coil and a switch. The inductance coil is connected between the voltage input terminal and ground. A warning unit is connected in series with the switch of the relay between the voltage input terminal and ground. A voltage regulating diode is connected between the voltage output terminal and ground. The anode of the voltage regulating diode is connected to ground, and the cathode of the voltage regulating diode is connected to the voltage output terminal.
