Operation function

- The NZ7 is designed with an allotted interval between disconnection and closing of the MC grid, so it will be able to protect the generator in the safest way.

- This device also has the ability to test the mains power before closing, so it can effectively protect the load.

- When there are some problems in the grid such as: complete loss, phase loss or voltage lower than the allowable value, Chint's automatic power converter will automatically send a signal to start the machine.

- There is a conversion time to the generator source ranging from 5 to 30 seconds.

- When the grid power is restored, the machine will run for 1-2 minutes to cool down and automatically transfer the load to the grid without user intervention.
- The ATS Chint Automatic Transfer Switch is designed with manual or automatic operation in mind.
- Most of Chint's automatic power converters are designed with an indicator light system and have the ability to adjust the switching interval.
