Key features

  • Control outputs: 4, 6 or 8
  • Auto-initialisation: detects number of capacitor banks, bank kVAr value and phase correction angle
  • Bank kVAr programmable as direct value, control series or auto-detected value
  • Intelligent bank switching for equal use of capacitors; capacitor health monitoring
  • Each output can be set to permanently ON, permanently OFF or auto
  • Manual mode for diagnosis and test run to measure connected bank kVAr
  • Alarm relay for high / low voltage, under / over current, over temperature, frequency faults, voltage / current harmonics, under and over compensation
  • Measures V, A, Hz, power, energy (import / export), demand, THD and individual harmonics up to 31st
  • High contrast 16 x 2 LCD with backlight
  • Optional Modbus (RS485) output and RTC
