1. Product Overview
JGQ3 series automatic transfer switch (ATSE), is a set of switch and logic control in one, without the need for an external controller, truly realize the mechanical and electrical integration of the automatic transfer switch, it is suitable for AC 50Hz, rated voltage to 440V, the agreed heating current of 100A in the industrial and enterprise power distribution equipment, with voltage detection, frequency detection, communication interface, electrical and mechanical interlock and other functions, can achieve fully automatic, remote control, forced “0”, emergency manual operation, It is widely used in the automatic conversion of the main current and the standby power supply system or the automatic conversion and safety isolation of two load equipment. The switch is managed by the control circuit board issued by various logic commands, and the motor drives the operating mechanism of the main part of the switch, quickly connects the breaking circuit or converts the electrical appliance, and realizes safety isolation through the obvious visible state.
3. Description of switch structure
1. Electrical button: control the internal control line power supply of the control switch, and when the electrical button is automatic, the switch can be fully automatic and operational
Control and force the “0” operation, when the electrical button is manual, the switch can only be operated manually.
2. Operate the handle: When using the operation handle to operate manually, the electrical button must be in the manual state.
3. Mechanism padlock: special for maintenance, that is, first use the operating handle to make the switch in the “0” position, and then connect the padlock mechanism
padlock, can be overhauled (pick up the padlock to cut off the internal control power of the switch, the switch can not be automatic, and can not be realized by hand.)
moving).
4. Indicator: indicate the working state position of the switch (I, O, II)

Sixth, how to use
1. Fully automatic function: when the commonly used power supply is powered off, the switch will automatically switch to the standby power supply; When the standby power is restored to normal,
The switch automatically returns to backup power.
2. Forced “0” function: Start the forced “0” button, and the switch will cut off the dual power supply.
3. Remote control function: that is, remote control, press the “I” button; then the power supply is commonly used; Press the “II” position
button, then the standby power supply works; Press the “0” button to cut off the dual power supply.
4. Please select the switch function according to your needs and wire according to the corresponding function.
5. When ordering, please indicate the switch model, current specification and required function.
