220V dual power ATS cabinet, full name 220V dual power automatic transfer switch cabinet, is a specific application of Automatic Transfer Switch (ATS). It consists of one (or several) transfer switch electrical appliances and other necessary electrical appliances, which are used to detect 220V power circuits and automatically switch one or more load circuits from one power supply to another. Simply put, when the common power supply fails, it can automatically and quickly switch the load to the backup power supply to ensure continuous power supply to the load; when the common power supply returns to normal, it can automatically switch the load back to the common power supply.
