FAFW34030 series Modular active power filter

Power Factor Correction

The Aunilec APF not only compensate harmonic current but also the reactive power. It is able to correct for either a leading or lagging power factor.

Power Factor Correction

The Aunilec APF not only compensate harmonic current but also the reactive power. It is able to correct for either a leading or lagging power factor.

LCD Display

Aunilec APF LCD screen

The user friendly LCD display offers access to all parameters, waveforms, harmonic spectrum system power quality, settings, status and alarms, events log and multi-language.

Close/Open Loop Control

The CT is allowed to install at source or load side for measure the harmonic current from the load. When CT is installed at source side, the close loop control method is used for best accuracy of harmonic current compensation. (When CT is installed at the load side, the open loop control will be used)

Harmonic Current Generator

The Aunilec APF behaves like an harmonics current generator. It will measure the harmonic generated from the non-linear loads and cancel these harmonics with an opposite phase at the same amplitude.
