MDS7DT Series

DC Automatic Transfer Switch

The MDS7DT Series DC Automatic Transfer Switch is widely used for switching between DC power sources in various industries, such as power plants, petrochemical, and coal chemical sectors. The product ensures the stability of dual-circuit DC power supply while meeting the isolation requirements between the two power sources, effectively preventing mutual interference in the event of a ground fault in the DC system.
