■ ATS Dual Power Switching Cabinet Overview

　　The dual power switching cabinet (box) mainly realizes fully automatic switching between two power sources. That is, when the main power source fails, the backup power source automatically starts and automatically switches to the backup power source. If the main power source is restored, it automatically switches to the main power source, and the backup power source returns to standby status, thereby ensuring that the power distribution system is normal, stable, and sustainable.

　　The dual power switching cabinet (box) mainly realizes fully automatic switching between two power sources. That is, when the main power source fails, the dual power switching cabinet (box) remotely starts the backup power source and automatically switches to the backup power source. The system is powered by the backup power source. When the main power source is restored, the dual power switching cabinet (box) automatically switches to the main power source, and the system is powered by the main power source. The backup power source automatically returns to standby status; the dual power switching box has automatic and manual switching functions. If the automatic switching fails, the manual switching function can be used for emergency purposes. When the system malfunctions or requires maintenance, the dual power switching cabinet (box) can be manually switched to OFF to ensure the safe and reliable operation of the power distribution system; the dual power switching cabinet (box) can also monitor the power parameters (current, voltage, frequency, active power, reactive power, etc.) of the main and backup power sources, observe the parameters of the power source in real time, and understand the actual situation of the power distribution system more quickly and effectively. Dual power switching cabinets (boxes) are mainly used in data centers, airports, fire systems, and other areas where power outages are unacceptable.
