Automatic Transfer Switch (ATS) for Hahn & Sohn diesel generators, which automatically starts the generator and switches the power supply of the building in the event of a utility power outage. Designed for output up to 12 kW / 25 A, it is an ideal solution for backup power supply of homes, commercial premises, and technical facilities.
The Hahn & Sohn ATS 12 kW / 25 A automatic transfer switch is designed for fully automatic control of generator operation during a power outage. At the moment of interruption of the public grid supply, the ATS unit automatically sends a signal to start the generator, switches the power supply to the generator, and after the grid is restored, the entire process is returned back automatically without operator intervention.
- The unit is equipped with a clear control panel with LED status indication (grid, generator, automatic mode, fault) and allows automatic as well as manual operation. The robust metal enclosure ensures long service life and safe operation even in demanding conditions.
- The ATS includes an integrated generator battery charger, protection against incorrect switching, and safety interlocking that prevents parallel connection of the grid and the generator.
