LT APFC RELAY- An inteligent high speed DSP + Microprocessor Based device to measure, calculate, display and store all electrical network parameters. In built Intelligent Multi Method Switching (MMS) Algorithm enables user to get close control on network reactive power requirement. Multi Method Switching (MMS) Algorithm allows user to set different target power factor for Diesel Generators and Windmill Stations. A built in self test facility provided for checking calibration and operation of the relay without external load. The control functions even at low operating loads with great accuracy

GB Control’s APFC controller find usage and applications in all segments of industry viz Automobile Factories, Cement Plants, Chemical & Fertilizer Plants, Metal Industries, Hospitals, Windmill Power Stations, D .G. Stations etc.

The other built in features viz Over Voltage Protection, Low Voltage Protection, Under Load Protection, Over Load Protection High Temprature etc. provides nonstop operation of APFC System.
