The Danfoss ACI analogue 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.
