Overview

The wall-mounted AFQm multilevel active filters are the most complete solution for solving power quality problems in three-phase industrial, commercial or service installations caused by the presence of harmonics and the consumption of reactive power. These following characteristics and functions have been implemented:

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

Key Features

  • Filtering capacity of 30 A, 75 A and 100 A
  • Small wall-mounted cabinet easy to install thanks to its small dimensions
  • Range 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 fiftieth harmonic (2,500 Hz)
  • Selection of harmonic frequencies to be filtered for maximum filter effectiveness
  • Power factor correction both inductive and capacitive
  • Phase current balancing, improvement of consumption in neutral (4W model)

Applications

They are an ideal solution for installations with a large amount of single-phase and three-phase loads generating harmonics, such as computers, UPS units, lights, lifting equipment, air-conditioning systems with variable speed drives, etc.
They can also be used in installations that require a good power quality for the purpose of increasing production efficiency and improve supply continuity in the system.
