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

Last step of power factor controller is normally working as a standard step but it can be removed from regulation algorithm and used for alarm purposes. Configuration of last step alarm output is easy to be enabled in setup menu.

Circular switching

Within a group of the same powers of capacitor steps, controller uses so called circular switching method. Controller uses the step that was disconnected longest time in order to balance equal usage of all capacitors.

Software

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