ATyS t
  • ATyS t 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/transformer 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 two 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 t switches offer significant time saving during commissioning (process takes 2 to 3 minutes). Because they have only two potentiometers and four DIP switches, a simple screwdriver is all you need 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 t products are automatic changeover switches intended specifically for transformer/ transformer 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 three-phase and single-phase networks.
