ACI CI-Tronic Analog Power Controller

Brand: Danfoss

The ACI Analog power controller is designed for very precise temperature and transformer control. 

Due to the built-in micro-computer, the controller can operate in phase angle as well as in burst firing control method.

The controller automatically adapts to the load to ensure a smooth inrush, and in burst-firing mode it will further eliminate the unwanted effects of DC magnetizing on transformers.

The ACI unit is easily connected to a PLC regulator by means of one of the selectable input signals.
