Mini ATS Automatic and Manual Power Dual Transfer Switch, Solar Switch with Surge and Under Voltage Protection, DIN Rail Mount (4P-63A,CA220V)

It is mainly used for automatic or manual switching between two power sources and can check the working status of the main power supply and backup power supply. Both power supply A and power supply B can be connected to the power grid, generators or photovoltaic systems. 110V overvoltage and undervoltage protection: undervoltage threshold 85V, recovery value 95V; surge threshold 145V, recovery value 130V. Overvoltage and undervoltage protection 220V: undervoltage threshold 175V, recovery 195V; surge threshold 260V, recovery value 240V. When the main power supply has an abnormality, the backup power supply immediately goes into operation, ensuring the continuity, reliability and safety of the power supply. It does not guarantee a completely zero power outage, but minimizes the inconvenience of power outages. As soon as the main power supply returns to normal, the device automatically switches from the backup power to the main power. It is ideal for environments that cannot withstand power outages, such as hospitals, cold stores, data centers and other high-demand places. In the event of a failure of the main power, it ensures fast and automatic switching to the backup source to ensure a safe and reliable power supply. This equipment is equipped with indicator lights. In automatic mode, the red light of the power supply A will light up when it is working properly; in case of a fault of the power A, its green indicator turns off. In manual mode, to select the power A, simply turn the right red handle to position A to turn on its red light. To choose power B, manually operate the red right handle to position B to activate its red light.
