Harmonic filter for active power factor correction

The AHFW active filter is an advanced solution for power factor correction in electrical installations. Designed to mitigate harmonics, balance phases, and compensate for reactive power, the AHFW delivers efficiency and reliability in systems with high load variation. It is suitable for both industrial and commercial environments, ensuring stable and safe operation under challenging conditions.

Key features

  • Operating voltage up to 690 V
  • Module ratings: 50, 100, and 150 A
  • Models available for rack-mount and wall-mount installation
  • Modbus RTU communication protocol

Benefits of active correction

  • Harmonic compensation: attenuates distortions caused by harmonics up to the 50th order
  • Power factor correction for inductive or capacitive reactive power: ensures a power factor (PF) ≥0.99, minimizing energy losses
  • Phase balancing: reduces imbalances to less than 5%, increasing system efficiency
  • High control capability: response time ≤5 ms
  • Energy efficiency: power consumption ≤2.5% of rated capacity
  • Communication via RS485 with Modbus-RTU protocol
