ATyS g are 3 or 4 pole automatic transfer switches, with positive break indication. They incorporate all the functions offered by the ATyS r, as well as 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 potentiometers and DIP switches. Remote monitoring of the ATyS g is possible with the optional RS485 communication module.
They are intended for use in low voltage power supply systems where a brief interruption of the load supply is acceptable during transfer.
ATyS g switches offer significant time saving during commissioning (process takes 2 to 3 minutes). Owing to the design that allows commissioning through just four potentiometers and four DIP switches, a screwdriver is all that is required to configure the parameters.
For added simplicity, they also offer an autoconfiguration function which enables automatic adjustment of the rated voltage and frequency.
Specifically designed for mains/mains and mains/genset applications
The ATyS g’s integrated controller has been designed to provide specific functions for these applications (genset startup, on-load or off-load tests...) together with the monitoring of the voltage and frequency of both sources
for three-phase and single-phase networks.
The generator supply must be connected to switch II, located at the rear.
An optional RS485 communication module (p/n 4825 0092) can be fitted to the AtyS g controller.
It allows remote monitoring of available power sources and their parameters, timers, as well as displaying the product’s status and configuration.
Communication speed is up to 38400 bauds.
Watchdog relay to check product availability
ATyS g products are equipped with a Watchdog relay which constantly monitors your product, thereby securing the installation.
This relay informs in real time the user of the product's availability, i.e. whether it is operational and ready for source switching.
Integrated auxiliary contacts
As part of the product monitoring function, the ATyS g enable the transmission of information relating to their position. This is possible thanks to the standard integration of an auxiliary contact for each position.
Extended power supply range
ATyS g products offer greater availability thanks to their extensive power supply range of 208 to 277 VAC ± 20%.
The updated design includes metal mounting legs across the entire ATyS range, improving the overall robustness of the switches. It also allows an easier and trouble-free mounting of the switches on a back plate with preassembled screws.
