Active multifunction filter

Description

The AFQevo cabinet series parallel multifunction active filter is the most complete solution for solving Quality problems related to industrial, commercial or services installations with presence of harmonics, consumption of reactive power (usually capacitive) and also phase unbalance. This AFQevo is meant rack mounting into market standard cabinets, designed to facilitate its installation.

 The implemented features and functions are:

• Filtering capacity from 100 to 200 A for each cabinet.
• Reduced rack dimensions to be installed easily in standard cabinets.
• Range of filters for installations with 3 wires (3W model) or 4 wires (4W model).
• Multirange, dual frequency (50/60 Hz)
• Reduction of harmonic currents up to the 50th harmonic (2500 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 also helps to reduce consumption in neutral.

If higher capacities are required, the system can be expanded with AFQevo racks in parallel (all the filters/racks must be the same model, 3 or 4 wires).

Applications

Ideal solution for installations with large amounts of single-phase and three-phase loads that generate harmonics, such as computers, UPS’s, lights’ units, air-conditioning systems with phase shifters, etc. Also for installations that requires high power Quality to increase the production efficiency or reduce supply continuity of the system.
