Dual Power Automatic Transfer Switch, Two Inputs One Output Jgq3-100 4p

I. Product Overview

 The JGQ3 series automatic transfer switch (ATSE) is an automatic transfer switch that integrates the switch and logic control into one unit, requires no external controller, and truly achieves electromechanical integration. It is suitable for industrial enterprise power distribution equipment with AC 50Hz, rated voltage up to 440V, and conventional free air thermal current of 100A. It features voltage detection, frequency detection, communication interface, electrical and mechanical interlocking, and other functions, and can realize fully automatic operation, remote control, forced setting to "0", and emergency manual operation. It is widely used for automatic transfer between the main power supply and the backup power supply in power supply systems, or for automatic transfer between two load devices, as well as for safety isolation. In the switch, the control circuit board issues various logic commands to manage the motor, and the motor drives the operating mechanism of the main body of the switch, quickly making and breaking the circuit or performing electrical transfer, achieving safety isolation through a clearly visible status.

III. Switch Structure Description
1. Electrical button: Controls the internal control circuit power supply of the switch. When the electrical button is in automatic mode, the switch can perform fully automatic, remote control, and forced “0” operations. When the electrical button is in manual mode, the switch can only be operated manually.
2. Operating handle: When using the operating handle for manual operation, the electrical button must be in manual mode.
3. Mechanism padlock: For maintenance only. That is, first use the operating handle to place the switch in the “0” position, then attach the padlock to the padlock mechanism before maintenance can be performed. (Attaching the padlock cuts off the internal control power supply of the switch; the switch cannot operate automatically and cannot be operated manually.)

VI. Operating Instructions
1. Fully automatic function: When the normal power supply fails, the switch automatically transfers to the backup power supply; when the backup power supply returns to normal, the
switch automatically transfers back to the backup power supply.
2. Forced "0" function: Press the forced "0" button, and the switch will cut off both power supplies.
3. Remote control function: That is, remote control. Press the "I" position button, and the normal power supply operates; press the "II" position but
ton, and the backup power supply operates; press the "0" position button, and both power supplies are cut off.
4. Please select the switch function according to your needs and wire it according to the corresponding function.
5. When ordering, please specify the switch model, current specification, and required functions.
