Automatic Transfer Switching Equipment from 125 to 3200 A

ATyS p are three-phase automatic transfer switches, 3 or 4 poles, with positive break indication. They incorporate all the functions offered by the ATyS t and g, as well as functions designed for power management and communication. In automatic mode they enable the monitoring of, and the on load changeover switching between, two power supply sources, in accordance with the parameters configured via an LCD display or via the communication.

They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer.


Recording of events
ATyS p switches enable effective monitoring of your installation thanks to timestamped event recording. Events can be retrieved and read via the communication system.

Optional communication modules
The ATyS p offers communication functions thanks to the addition of optional modules, such as the RS485 module for Modbus communication or the Ethernet module, which includes a Webserver.

Configuration software
Software (Easyconfig) is available enabling the ATyS p parameters to be easily configured and the existing configuration to be saved.

Power measurements
ATyS p products are particularly suited to energy management and monitoring. In addition to their integrated power and energy measurement functions (with a 2% accuracy level), programmable inputs/outputs can be utilised to control load shedding based on a load level or tariff.

Possibility to set periodic genset startup
ATyS p switches offer additional functions for maintenance. They include the programmed genset starting function which allows the starting dates and operating times to be configured.
