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.
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.
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.
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.
