Product Introduction

Active Harmonic Filter

How Active Harmonic Filters Work

Active Harmonic Filters are filters, and a perfect comprehensive solution to power quality problems with the grid, such as harmonics, reactive power, and three-phase load imbalance. AHF can be used to filter out harmonics in the power system that are significantly below the switching frequency of the filter.

AHF is used to filter out both higher and lower orders of harmonics in an electrical system.

Key Features & Benefits:

Real-Time Compensation: Instant detection and cancellation of harmonics (THiD <5%).

Wide Application Range: Supports low/medium voltage systems (208V–690V, 50/60Hz).

Multi-Functionality:

Harmonic filtering (up to 95% efficiency).

Reactive power compensation (power factor ≥0.98).

Load balancing (for 3-phase systems).

Modular Design: Scalable capacity (50A–1000A+) for flexible deployment.

Robust Protection: Overload, short-circuit, and overheating safeguards.

Smart Monitoring: Built-in analytics with communication protocols (Modbus, Ethernet).
