This equipment satisfies electrical requirements and criteria of the:

  • Electrical Equipment (Safety) Regulations 1994 (S.I. 1994/3260)
  • BS EN 61439-2
  • IEC 61439-2
  • CE Certification


The controller displays a digital output of the power factor being achieved on the connected supply and can be used to view many power values: Voltage, current, THD, KW, KVA and KVAr. Alarms indicating equipment failure are pre-programmed. Other alarms which can be connected to lights or sirens can also be programmed via the interface.

All components within the equipment are manufactured in the EU. The enclosure and controller UK, all isolation, fuse bases, fuses, contactors are German, and the capacitors and reactor are from the Czech Republic. All components have been proved on many UK sites for many years and have been selected as they are the best in relation to maintaining output and failure rate.
