PFC Controller

Power Factor Correction

PFC Controller

1.Product Features

1. Real-time display of power factor φ, voltage, current, active power, reactive power, voltage total harmonic distortion rate, current total harmonic distortion rate, frequency, capacitance output display and switching status and various protection overrun alarms and other information.

2. Capacitor input delay and removal delay can be set separately, with high compensation efficiency, input and removal thresholds can be preset and high compensation accuracy.

3. It has the functions of harmonic voltage and current measurement and protection, and power failure protection; it has two working modes of manual compensation and automatic compensation; it has standard field bus communication interface which is convenient for connecting to the intelligent switch cabinet system.

4. Adhering to the people-oriented design concept, modular assembly, full digital design, the human-machine interface adopts a large-screen English LCD display.

5. Signal AC sampling, strong anti-interference ability, avoid misoperation, high work reliability; can accurately judge reactive power and power factor, and avoid oscillation switching phenomenon.
