Analogue power controllers Type ACI
General
Type
ACI 30-1
ACI 50-1
Product description
The versatile 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.
Typical applications
Analogue control of heaters and infrared lamps. The ACI controller is also ideal on transformer controlled processes.
