Wall-Mounted AFQm Multilevel Active Filters

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.

Characteristics and Functions

• 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)
• 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).

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

They can also be used in installations that require a good power quality to increase production efficiency and improve supply continuity in the system.
