ATyS C25

ATS Controller
Dip switch configuration

ATyS C25 is an entry level ATSE controller with communications. It can be used to pilot a remotely operated transfer switch, such as ATyS r, ATyS S and ATyS d M, as well as contactors. ATyS C25 ensure the automatic or remotely controlled transfer from one source to another with fixed timers and thresholds.


Flexible space saving

The ATyS C25 controller can be mounted on either a DIN rail or to the panel door, offering flexibility and optimising space.


The ATyS C25 has an integrated DPS, for supplying the motorisation of the switch, and can be door mounted, therefore there’s no need for an external DPS or display, reducing installation time and costs.
