Automatic transfer switch (ZLQ5)

Product characteristics:

1. Reliable mechanical interlocking, without closing of two power supply at the same time.

2. Complete detection functions, such as missed phase, over voltage, under voltage and power supply frequency of self-prepared generator set (selectable). It has the features of high precision for detection, huge range for judging the parameter.

3. It has excellent EMC, and takes the lead of passing the test in China.

4. Main body of the switch has excellent function of mechanical isolation, additional function of adding and taking off load.

5. Four poles switch has operating feature of N pole closing first and breaking later.

6. It has padlock function, lock the zero position to avoiding wrong operation.

7. It can operate with fire protection system, cut off no fire protection load via setting in zero position remotely to avoid electric fire. It can assemble various hardware interface board, support various field bus protocol.

8. The automatic transfer switch has complete electromechanically integrated structure, small volume, install and debug easily.

9. The two power supply can be set to normal power supply or emergency power supply discretionarily.

10. Control power supply of the inner driving electromotor could automatically select one power supply which can satisfy the quality requirement.

11. It has three positions for switch: I-0-II.

12. It has three operation modes: manual, automatic, electric.
