ATyS A are 4 pole automatic transfer switches, with positive break indication.
They incorporate the functions intended for mains/mains and mains/genset applications.
In automatic mode they enable the monitoring of, and the on-load changeover between, two power supply sources, in accordance with the parameters configured via DIP switches.
They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer.

Conformity to standards

IEC 60947-6-1


Rapid commissioning

Voltage tapping and cable harness are supplied in a single package with motorised transfer switch
and ATS controller. ATyS A switches offer significant time saving during commissioning (process takes 2 to 3 minutes). Owing to the design that allows commissioning through eight DIP switches, a screwdriver is all that is required.

Watchdog relay to check product availability

ATyS A products are equipped with a Watchdog relay which constantly monitors your product, thereby securing the installation. This relay informs the user of the product's availability in real time, i.e. whether it is operational and ready for source switching.

Cable harness

The cable harness is an easy way of powering ATyS A transfer switch systems. It is equipped with voltage tap offs and provides a reliable link between the controller and changeover switch for:
- tracking power sources availability,
- monitoring changeover switch availability,
- an electrical interlock function,
- control and transfer between power sources.
Cable harness length is approximately 2 metres.

All in one TSE

The design of the ATyS A transfer switch offers easy door mounting of the ATS controller across the cabinet. Whilst providing an IP4x protection degree it enables acces to source availability and switch position visual information, as well as to the manual remote controls option.
