TKDQ series automatic transfer switch
The TKDQ series dual-power automatic transfer switch is suitable for two-power supply systems with a rated voltage of AC400V, a frequency of 50Hz, and a rated working current of up to 1600A. It serves as a switching device between the normal power supply and the backup power supply. When one power supply fails, it automatically switches between the normal and backup power supplies to ensure the continuity of power supply to important equipment. At the same time, it can provide short-circuit and overload protection for the downstream load and cables. It is mainly used in industrial control, fire protection, banks, and other important places where power outages are not allowed. Standards compliance: |
