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.
