ATyS g

from 125 to 3200 A

ATyS g
  • ATyS g is a range of three-phase automatic changeover switches with positive break indication. They incorporate all the functions offered by the ATyS d, as well as functions intended for transformer/generator applications.
  • 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 four potentiometers and four DIP switches. They are intended for use in low voltage power systems where interruption of the load supply is acceptable during transfer.
Rapid commissioning
  • ATyS g switches offer significant time saving during commissioning (process takes approximately 5 minutes). Because they have only four potentiometers and four DIP switches, a screwdriver is all that is needed to configure the parameters. For added simplicity, they also offer an autoconfiguration function which enables automatic adjustment of the rated voltage and frequency.
Functions adapted to transformer/transformer applications
  • ATyS g products are automatic changeover switches intended specifically for transformer/generator applications. Their integrated controller has been designed to provide all the functions necessary for these applications, including monitoring the voltage and frequency of both sources, for threephase and single-phase networks.
Generator test functions
  • To ensure compatibility with transformer/generator applications, ATyS g switches integrate the following generator test functions:
  • Test on load and test off load.
