Concebido pelos especialistas de "Segurança e Controlo de Alimentação", o ATyS S fornece claras vantagens técnicas e diferenciação para Aplicações de Alimentação em Standby Genset com cargas até 125 A (< 90 kVA / 415 Vca). ATyS S is a range of 4 pole 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. Advantages Extensive power supply range The ATyS S is available in four supply versions, each with a broad range (+/-30%). The four versions are: • 230 VAC single power supply, • 2 x 230VAC dual power supply, • 12 VDC power supply and • 24/48 VDC 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 Sd: Dual power supply In addition to the functions offered by the ATyS S, the ATyS Sd incorporates supply redundancy without the need for additional wiring. This is obtained by integrating a double supply (2 independent supplies) directly within the product.
