We are unique Name in this industry to provide our prestigious clients an exclusive Range of APFC Relays. APFC Relay for power factor correction in Low voltage applications measure the actual power factor and connect or disconnect capacitors to achieve a target power factor. The single phase electronic measuring system detects the reactive and active components of the network through the current and voltage path. From this phase swift between current and voltage and compares this with the set target power factor. * User friendly program for target power factor stages, on/off delay, CT ratio, Dead Band, Current, PFCR. Seven segment LED display 4 digits Recall function of recorded values. Available in 6, 8, 12, stages. User configurable parameters, Target PF setting, Power Factor Tolerance, CT ratio,under current, time delay between steps (1 sec. - 60 sec.). APFC unit (ATSO) should work on single phase, Single C/T. Real time power factor will display on FND in Normal condition. No load as C/T Reverse Fault will Display on FND Lead, Lag, Auto, Manual & Capacitors Status Indication Available on APFC unit Automatic switching off Relays should be done as per Rotation of method. Suitable for balanced unbalanced fluctuation load. Advance microprocessor Based Power Factor Controllers
