Active Harmonic Filters
Eliminate harmful electrical distortions to protect sensitive equipment and maintain stable, reliable power quality in high-demand environments.
What Are Harmonic Currents and Voltages?
In a perfect electrical system, voltage and current waveforms follow a smooth sine wave at a fundamental frequency (e.g., 50Hz in Australia). However, modern electrical equipment such as Variable Speed Drives (VSDs), LED lighting. computers, and uninterruptible power supplies (UPS) don't draw power smoothly. These devices create non-linear loads and introduce unwanted electrical noise, known as harmonics-distortions in the current and voltage

Active Harmonic Filter Wall-Mount Units
Compact, space-saving design - ideal for installations with limited floor space. Can be paralleled for larger capacity
Rated voltage and frequency - Supports 400-690V
Harmonic filtering performance - Targets harmonics from 3rd to 51st order, achieving total harmonic current distortion (TH Di) under 5%, with filtering rates up to 98%
Core technologies - Utilises a 3-level neutral-point-clamped (N PC) IGBT inverter, high-speed DSP + FFT for fast detection and compensation (full response <10ms) with 20kHz switching frequency
Multi-function support - Provides harmonic mitigation, reactive power correction (leading/lagging), and three-phase imbalance balancing
High efficiency – Maintains ≥99% efficiency with power loss ≤1%; stable operation avoids resonance issues
Protection & communication - Offers 16 protection features
Standards compliance - Built to I EC61000 / 62477 standards with 3-year warranty
Scalable installation options - Can be wall-mounted as standalone units or linked together for higher capacities; alternatively integrated into floor-standing cabinets
Ideal applications - Suited to small industrial setups, commercial buildings, data centres with limited space, and renewable energy systems
Why choose a wall-mounted cabinet
Superior space efficiency - Frees up floor area with vertical mounting.
Plug-and-play simplicity - Quick, minimal-complexity installation.
Robust compensation performance - Delivers fast, real-time harmonic and reactive correction with high reliability.
