Particular features include:

  • Incoming mains isolator and door interlock
  • Multifunction LCD display of voltage, current, power factor (cos Φ), operating status and system faults
  • In built protection for overcurrent, over or under voltage, phase sequence and phase failure.
  • In built power factor dry run protection or connections for remote low level float switch/probes provided.
  • Connections for various analogue (e.g. pressure and float switch) or digital (eg PLC's and transducers) signal inputs provided.
  • Large enclosure with space for capacitors in single phase pump installations.
  • Adjustable maximum operating current and voltage limit settings.
  • Twin pump controllers provide for selection of duty/standby, alternate duty cycling with auto trip changeover and parallel operation configurations.
