Power Factor Control Relay (BLR-CM 3-Phase)

Power Factor Control Relay BLR-CM 3-phase

Microprocessor controlled power factor controlled with 3-phase measurement system and display of measurement values

  • Full-automatic c/k-value setting, self adapting, connection of different capacitor step sizes possible
  • Capacitors and detected or programmed with values in all three phases. This allows using single-phase or three-phase capacitors in any sequence
  • Automatic detection and usage of the optimum capacitor step
  • Manual mode possible
  • multiple connecting types possible through adjustable phase compensation angle
  • Capable for 4-quadrant operation
  • Individually configurable discharging time allows quicker switching time 
  • 3-phase measurement system also suitable for non-sinusodial currents and voltages
  • Graphical LCD for display of step status, measurement values and system data
