Function
Controller ICR is reading, directly or via optical separation unit, pulses from static energy meter. Base on the pulse weight and time distance between particular pulses, controller calculates active and reactive powers. At low signal frequency of measuring pulses, controller corrects power values depending on running time.
Smart decompensation system
ICR controller is solution for decompensation of capacitive loads such as photovoltaic power plants or system with long cables. Controller is tuning decompensation reactor by capacitor steps in order to obtain the needed reactive inductive power for capacitive load decompensation. It brings easier and cheaper PFC construction by using only one decompensation reactor.
Internal power supply
Controller has builtin 12 V DC power supply for supplying the energy meter pulse outputs. Internal power supply is fully metallically separated from the controller.
OLED display
Bright and fully graphic OLED display gives another dimension to power factor controller. It provides monitoring features to give easy understanding overview about the system situation.
