ATyS – ATyS d

from 125 to 3200 A

ATyS - ATyS d
  • The ATyS and ATyS d are three-phase motorised changeover switches with positive break indication. They enable the on load transfer of two three-phase supplies via remote volt-free contacts, from either an external automatic controller, using pulse logic, or a switch. They are intended for use in low voltage power systems where interruption of the load supply is acceptable during transfer.
Watchdog relay to check product availability
  • ATyS and ATyS d products are equipped with a Watchdog relay which constantly monitors the product, thereby securing your installation. This relay informs the user of the product’s availability, i.e. whether it is operational and ready for source switching.
Integrated auxiliary contacts
  • As part of the product monitoring function, the ATyS and ATyS d enable the transmission of information relating to their position. This is possible thanks to the standard integration of an auxiliary contact for each position.
Extended power supply range
  • ATyS and ATyS d products offer greater availability thanks to their extensive power supply range of 208 to 277 VAC ± 20%.
ATyS d: ATyS with integrated DPS
  • In addition to the functions offered by the ATyS, the ATyS d incorporates supply redundancy without the need for additional wiring. This is obtained by integrating a double supply (2 independent supplies) directly within the product.
