Electronic Filter

We offer a complete product range of Active Harmonic Filter

Active Harmonic Filter

User selectable priority adjustment between Harmonics, PF correction and Load unbalance compensation.

Selective harmonics filtering - Up to 9 selected Harmonics. User defined harmonic spectrum or with auto selection of highest harmonics on supply system.
Reactive power compensation per individual phase Enable/Disable with target PF setting from 0.7 Capacitive to 0.7 Inductive.
Load Unbalance compensation- Enable/Disable with limit settings.
Additional filter for reduced PWM ripple current (< 2% pk-pk)
Closed loop control system for precise and effective compensation with high speed reaction time of < 300 micro-Second and response time of about one supply mains cycle.
Unique Algorithm with current source pulse width modulation (PWM) giving high reliability of the operation to work under adverse supply PQ problems.
Filtering efficiency > 94%.
Wide range rating from 15Amp to 300 Amp in a single cubicle.
