Mini ATS Automatic and Manual Power Dual Transfer Switch, Solar Switch with Surge and Under Voltage Protection, DIN Rail Mount (2P-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. Over voltage and under voltage protection 110V: 110V/50Hz: under voltage threshold 85V, recovery value 95V; over voltage threshold 145V, recovery value 130V (±5V). Over voltage and under voltage protection 220V: 220V/50Hz: under voltage threshold 175V, recovery value 195V; over voltage threshold 260V, recovery value 240V (±5V). When the main power supply has an anomaly, the emergency power supply immediately goes into service, thus ensuring the continuity, reliability, and safety of the electrical supply. It does not guarantee a total power outage, but reduces to the maximum the inconveniences related to power failures. As soon as the main power supply returns to normal, the device automatically switches from the emergency power supply to the main power supply. 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 indicator light of power supply A lights up when it is functioning correctly; in case of a fault in power supply A, its green light turns off. In manual mode, to select power supply A, simply turn the right red handle to position A to light up its red indicator. To choose power supply B, manually move the right red handle to position B to activate its red indicator.
