OVERVIEW:

ATyS S products are 4 pole remotely operated transfer 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 supply systems where a brief interruption of the load supply is acceptable during transfer.

Advantages:

Extensive power supply range:

The ATyS S is available in four supply versions, each with a broad range (+/-30%). The four versions are:

• 12 VDC power supply.

• 24/48 VDC power supply.

• 230 VAC single power supply.

• 2 x 230 VAC dual power supply.

Safety and reliability:

ATyS S products use stable position technology, ensuring constant pressure on the contacts and preventing premature faults. In addition, they do not require a power supply to maintain position, thus protecting their loads from voltage fluctuations.

Easy integration:

ATyS S products can be easily installed inside enclosures. Their design, and in particular their compact size, enables integration within most 200 mm deep enclosures.

Simplified maintenance:

Maintenance can be carried out easily under load, with manual operation still available. The control and motorisation section can be replaced simply by removing 4 screws, with no work required on the installation cabling.

ATyS d S: Dual power supply:

In addition to the functions offered by the ATyS S, the ATyS d S incorporates supply redundancy without the need for additional wiring.This is obtained by integrating a double

supply (2 independent supplies) directly within the product.=
