Active multifunction filter, 50 / 60 Hz

Description

The floor 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 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 
• 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)

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.
