Active multifunction filter

Description

The AFQevo parallel multifunction active filter is the most complete solution for solving power quality problems related to  industrial, commercial or service installations with presence of harmonics, consumption of reactive power (usually capacitive) and also phase unbalance. The AFQevo is meant for wall-mounting thanks to its small size to facilitate its installation.

The features and functions implemented are:

—   Filtering capacity of 30 A

—   Reduced metallic enclosure for wall assembly. Its compact dimensions make
      it easy to install.

—   Range of filters for installations with 3 wires (3W model) or 4 wires (4W model)
—   Multi-range voltage and dual frequency (50/60 Hz).

—   Reduction of harmonic currents up to the 50th harmonic (2,500 Hz).

—   Selection of harmonic frequencies to be filtered so to reach the filter’s highest effectiveness.
—   Power factor correction. Both inductive and capacitive currents.

—   Phase current balancing. In the 4W model, it helps to reduce consumption in neutral.

If higher filtering capabilities are required, the system can be expanded with up to 100 AFQevo connected in parallel (the filters must all be of the same 3 or 4-wire model).

Applications

Ideal solution for installations with large amounts of single-phase and three-phase loads that generate harmonics, such as computers, UPS's, lights, lifting units, air-conditioning systems with phase shifters, etc.
