The series SGLD automatic transfer switch equipment (ATSE) is such a new product that integrates switch and logic control to truly realize the mechatronics; it applies at the distribution device of rated insulation voltage up to 1000V and rated frequency of 50Hz and rated voltage up to 660V and conventional heat current up to 3200A. to automatically transfer between the master power and the backup one in the power supply system or the two load devices and perform the secure isolation, wide used at the important occasions, e.g. hospital,marketplace,bank,highrise building,coal mine,communication department,iron mine,expressway, airport, product line and military facilities where the power interruption is taboo.

The switch equipment utilizes the control circuit to send various logic command to control the motor the turn of which, after speed reduction by gearcase, would drive the operating mechanism that accumulates the energy with the spring and performs the instantaneous release so as to quickly make and break the circuit or perform the circuit transfer and realize the secure isolation by obviously visual state.

The switch equipment could perform the full automatic operation, compulsively setting "0" remote control and emergency hand operation, moreover, it could perform detection and protection for phase lack, detection and protection for undervoltage, detection and protection for frequency, delay adjustment and electrical & mechanical interlock, etc.

The switch equipment features attractive appearance, novel and compact structure, small dimension and complete function, leading the counterpart.

Switch Function:

1.Full automation: i.e. self-operatin&self-reset. When the backup power supply presents the power interruption, the switch equipment would automatically connect with the backup power supply; however, when the duty power supply recovers, the switch equipment would automatically connect with the duty one.

2.Compulsively setting "0": In case of the emergency or maintenance, it is to start the compulsive "0" self-lock button switch equipment to automatically stand at the position "0" to cut the dual power supply.

3.Remote control: i.e. control by the remote operation. Starting the position "I" of button to make the duty power supply work and, starting the position "II”to make the backup power supply work.

4.Detection and protection for phase lack: Detect the power interruption at the duty or backup power supply and perform the necessary protection.

5.Detection and protection for overvoltage: Detect the overvoltage at any phase of the duty or backup power supply and perform the necessary protection. Clockwise adjustment to lower the protection threshold for the overvoltage and anticlock wise adjustment to lift the the protection threshold for the overvoltage.

6.Detection and protection for undervoltage: Detect the undervoltage at any phase of the duty or backup power supply and perform the necessary protection. Clockwise adjustment to lower the protection threshold for the undervoltage and anticlock wise adjustment to lift the the protection threshold for the under voltage.

7.Detection and protection for frequency: Detect the frequency of the backup power supply(generating). Clockwise adjustment to lift the protection threshold for the frequency and anticlockwise adjustment to lower the the protection threshold forthe frequency.

8.Delay adjustment: The delay before automatic transfer of the adjustment switch. Clockwise adjustment to increase the delay and anticlock wise adjustment to decrease the delay.

The switch meets the standards of IEC 60947-6-1 and GR 14048.11
