ATS EXT3

This transfer switch is suitable for dual power supply systems with AC 50Hz, rated working voltage up to 400V, and rated current from 10A to 63A. It would detect the Normal power (N) and back up power (R) of the power supply system at the same time. When there is over voltage, under voltage, or open phase error, it will automatically switch from the abnormal power supply to the normal power supply (it can also be set to manually switch) to improve the continuity, safety and reliability of the power supply system in the place of use.
