Active Harmonic Filter

High Quality Harmonic Filter

The use of filtering in cases of harmonic distortion can reduce overheating of equipment and nuisance tripping of circuit breakers and fuses. It can also improve power quality contributing to reduced energy costs. We use a high-quality Circutor Active Harmonic Filter and have a number of systems available to suit your commercial or industrial needs. The cleaner the grid, the greater the benefit.

AFQm 30/60/100

The wall-mounted AFQm multilevel active filter is 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:

• Filtering capacity of 30 A, 60 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).

AFQm 100/200/300/400

The floor-mounted AFQm multilevel active filter is 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 in the cabinet type active filters:

• Filtering capacity per module of 100 A, capacity per cabinet between 100 A to 400 A
• Cabinets expandable with small-sized rack modules
• 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 xx Phase current balancing, improvement of consumption in neutral (4W model)
• If higher filtering capabilities are required, the system can be expanded using AFQm racks connected in parallel (all filters/racks must be of the same 3- or 4-wire model)
