Strong Points

Function

They enable the on-load transfer of two three-phase power 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. The ATyS d is a remote transfer switching equipment (RTSE) with an integrated dual power supply (DPS).

Advantages

Permanent product availability monitoring relay

ATyS d products are equipped with a Watchdog relay which constantly monitors your product, thereby securing the installation.
This relay informs in real time 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 d enables 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 d products offer greater availability thanks to their extensive power supply range of 208 to 277 VAC ± 20%.

Integrated dual power supply

The ATyS d incorporates supply redundancy without the need for additional wiring. This is obtained by integrating a double supply (2 independent power supplies) directly within the product.

Even more robust

The updated design includes metal mounting legs across the entire ATyS range, improving the overall robustness of the switches. It also allows an easier and trouble-free mounting of the switches on a back plate with preassembled screws.
