Function
Device digitizes measured phase voltage and current in one phase. Then, from those values, parameters like: power factor, effective values of voltage and current, apparent power and reactive power, are calculated. With consideration of requested cosφ it calculated need compensation power. According to its size, regulator switches on or off appropriate capacitor stages.
Within the scope of each power level, regulator uses method of circle switching. All the time connects this stage at appropriate power level which was switched off for longest time. Everything is made so that regulator will reach optimal compensation in one regulation cycle with minimum number of switched stages.
Alarms
Power factor controllers FCR06 and FCR12 have several alarms which are adjustable by level, min time of event, action on regulated steps etc. Special alarm from temperature is able to control forced ventilation of PFC and protect capacitor steps against higher temperature.

Software
Thanks for software Power Monitor System is possible controllers with RS485 easily configured and also use for monitoring of PFC systems.
