Selection guide
The versatile ACI analogue power controller is
designed for very precise temperature and
transformer control. Due to the built-in
microprocessor the controller can operate in
phase angle as well as in burst ring control
mode.
The controller automatically adapts to the
load to ensure a smooth inrush, and in burst
ring mode it will further eliminate the
