PFC 10

 

Products > Control Equipment > PFC 10
PFC 10
Digital Power Factor Controller

The PFC-10 is used to continuously monitor and improve Power Factor.

A new generation of digital technology and True RMS measurement of

current Active/Reactive Power, enables accurate calculation of Power

Factor.

The PFC-10 offers unique features such as a Total Harmonic Distortion

Alarm which can be used to tripcapacitor banks when harmonic values

increases above allowed levels (in applications using large frequency

inverters, DC power supplies, etc.)

 

Advantages at a Glance

* True RMS voltage and current measurement,
   designed to operate in any industrial environment.
* Simple settings, automatic C/K adjustment, only 4
   parameters need to be adjusted in standard systems.
* Historical P.F display according to accumulated
   Active and Reactive Energies since last "Reset",
   allow comparison with utility's P.F. calculation.
* Measured / displayed THD with adj. alarm level
* Control voltages 115-400V, 50/60Hz
* Minimum measured current at 0.5%
* Optional- RS485 communication (MODBUS RTU)


THD Alarm

Rapid action for increased
capacitor protection


Communication

RS-485 with Modbus Protocol
(optional RS-232)


Displays

* Power Factor (Cos n)
* Power Factor history (Cos n avg.)
* Harmonics (up to 25th)
* Apparent Power (KVAR, MVAR)
* Power (KW, MW)
* Voltage (V)
* Current (A


Alarms

* Low Power Factor
* Wrong connection
* Low Current
* High THD
* Memory Protection


Switching Optimization

* One or Four quadrant system (software selected)
   with automatic correction in case of wrong C/T
   connection. Four quadrant in case of generated power.

* User selected switching modes (including FIFO)
   with adjustable time delay for "First Add Capacitor"
   step and between steps.

* Automatic override of small step switching, in the
   case of large demand, minimizes switching which
   extends life expectancy of capacitors and contactors.

* Prevents capacitor re-switching, for a 20 sec time
   delay, ensuring voltage was sufficiently reduced.

* Immediate trip of all steps in case of voltage
   outage. Automatic re-switching of connected steps
   after voltage restoration.
