MULTI PFR 12G (POWER FACTOR CONTROLLER 12 STEPS – RS485 BUILT IN)
Product: Power Factor Regulator
Model: MULTI PFR 12G
Description
An intelligent power factor controller that serves as the core component for automatic capacitor banks. It automatically manages the engagement and disengagement of capacitor steps to achieve the target power factor. The controller features a clear OLED display for monitoring key electrical parameters, including voltage, current, power, cos phi, individual harmonics up to the 19th order, and temperature via a built-in sensor. It also provides essential protection for the capacitor bank against over-voltage, high harmonic distortion (THD), and over-temperature.
