Power factor control relay with 6 stage output. Monitors incoming low voltage power supply quality via a current transducer. The PFC controller will switch in stages of capacitance to correct power factor as required by the demand of the supply.
This PFC controller also provides a comprehensive display of power and RMS values achieved on the supply. This includes power factor, KW, KVA, KVAR, harmonic distortion, voltage, current and can also be used to provide alarms for anomolies to these values.
Size common and can be used to directly replace old controllers in older power factor correction units.
