The surge blocking unit 210 is connected in parallel to the input terminal, and comprises a varistor (MOV1) and the arrester (A1) connected in series with each other.

A fuse F1 is connected to an input side of the surge interrupter 210 to block an overcurrent when a commercial AC power is applied.

The varistor MOV1 operates as if it is open (OFF) with a high resistance value below a specific voltage, but operates as if it is shorted because the resistance value is lowered above a specific voltage. Thus, when a surge overvoltage is input to the input terminal, it is turned on so that a current can flow.

The arrester A1 absorbs and blocks a current corresponding to a surge overvoltage introduced by the varistor MOV1 turned on. More specifically, the input current is avoided to ground so that the surge overvoltage component of the commercial AC power supply is no longer transmitted to the rear side.

The noise removing unit 220 is connected in parallel with a line filter LF1, capacitors C1 and C2 connected in parallel to both sides of the line filter LF1, and an output side of the line filter LF1. The point comprises a pair of capacitors C3 and C4 with ground FG.

The switching unit 230 is provided at the output terminal of the overvoltage circuit breaker, and is turned on and off by a switching operation to turn off when the commercial AC power is an overvoltage higher than a predetermined voltage so that the overvoltage is not supplied to the driving power supply unit 40.

In the present invention, when the commercial AC power exceeds AC 380V, the switching unit 230 is turned off to cut off.

In the present invention, although the relay is used as the switching unit 230, a transistor capable of switching operation, a thyristor, a triac, and the like may be used as the switching unit.

The detector 240 includes a current transformer CT1, a bridge diode BD1, a capacitor C8, and a resistor R9.

The current transformer CT1 induces a current flowing in the primary coil provided in the output line to the secondary coil according to the turns ratio, and detects the strength of the AC power output from the noise removing unit 220.

The bridge diode BD1 rectifies the power supplied to the secondary coil of the current transformer CT1. A capacitor C7 is connected between the current transformer CT1 and the bridge diode BD1 to smooth the AC power induced in the secondary coil of the current transformer CT1.

The capacitor C8 connected to the output of the bridge diode BD1 smoothes and directs the power rectified by the bridge diode BD1.

The resistor R9 connected to the output side of the capacitor C8 transfers the power DC-directed by the capacitor C8 to the controller.

The controller 250 includes a zener diode ZD3, an S1 U1, a first transistor Q1, and a second transistor Q2.

The zener diode (ZD3) is a detection signal of the detector 240, which is transmitted through the resistor (R9), that is, the AC power output from the noise removing unit 220 is converted into a DC through the detector 240 When the supplied power becomes an overvoltage of a predetermined voltage (for example, AC 380V) or more, the power is turned on and transferred to the SR U1.
