CA212 Basic Power Factor Controller

CA212 Basic Power Factor Controller

CA-212 power factor controller has been designed to ensure high accuracy in power factor regulation and excellent utilization of capacitor banks and relays in three phases 3 wire electrical grid. The common range for all network voltages is from 100V to 440V. The system reactive power compensation front panel is equipped with a 3-digit 7-segment display to show the present value of power factor voltage and line current.

Max 12 steps relay output for contactor, easy commission, and optional LCD display screen(provide power monitor function and CT ratio setting).
