GQ1 Series Dual Power Automatic Transfer SwitchDetailed product description：

Scope of application
GQ1 series dual power automatic transfer switch is suitable for dual power supply systems with AC 50, 60Hz, rated voltage below 690V, and rated current below 1250A. It can achieve automatic switching between the commonly used power source (N) and the backup power source (R) (which can also be set to manual switching), and can also automatically start the generator with the generator as the backup power source. The generator should have automatic starting hardware without the need for manual operation. Instantaneous interruption of power supply to the load during the conversion period. Mainly used in important places where power outages are not allowed, such as high-rise buildings, residential areas, hospitals, airports, docks, shopping malls, communication, fire protection, metallurgy, chemical industry, textiles, petroleum, coal mines, etc.
