Scope of application: Automatic Transfer Switch is applicable to ac 50HZ/60HZ, rated voltage 400V, rated current under 63A three-phase four-wire (or 1-phase first-line) dual power grid. this transfer switch can maintain uninterrupted power supply, it is designed for those situation unable to withstand continuous power outages, such as household emergencies, elevators,motorhome, firefighting etc.

This generator transfer switch connects two powers：one as normal power ("N"), the other as reserve power ("R"). If "N" fails, the ATS will transfer to "R", it means that 1 power supply fails (testing only the normal phase A voltage and the standby phase A voltage, and only the loss voltage or loss phase), the ATS (Automatice Transfer Switch) will automatically connect 1 or more load circuits from 1 power supply to another power supply to ensure the normal supply of the load circuit.

The dual power automatic transfer switch is mainly used to detect whether the power supply is normal or standby.When the power supply is normal, the standby power supply works simultaneously to ensure the continuity, reliability and safety of the power supply.

You can choose one of the 2 modes: "AUTO" or "MANUAL". If you need this ATS transfer automatically, set to "Auto", if "N" fails, the ATS will transfer to "R" automatically, when "N" goes back, it will transfer back to "N" again automatically. You can also choose "Manual" if you'd like to manually make the transfer.

Installation type :3 vertical installation or 4 horizontal installation
