ATS (Auto Transfer switch) is a system of automatic switching,  when electricity gone is generator  automatically started and shut power to the load. When gridpower recovery, system to transfer the power back and automatic shutdown the generator.

ATS  usually have protect functions when the power grid and power plant breakdown, such as phase loss, neutral loss ...

Operate Function of the  ATS:

- Automatically send a signal to start the machine: power grid loss safety , loss of phase grid, the grid voltage is lower than the value allowed.

- When the electricity restored, the ATS immediately transfer the load to the power grid, the machine automatically shut down after running cool.

- Ability to operate automatically.

- Adjustable switching time.

- Have a system indicator lights.
