Active Harmonic Filter

True Harmonics Solution

Amtech Electronics Active Harmonics Filter Manufacturer.

High harmonics escalate complications which affect all power distribution networks in industrial, commercial, telecom and medical applications.

Most of the power converting equipments or facilities can generate harmonic current. Axpert-i-Sine Series Multi-Functional Active Harmonic Filters are designed with intelligent control algorithm which dynamically adjust the switching frequency to optimize the performance and efficiency.

The performance of Axpert-i-Sine Series AHF is less affected by supply voltage harmonic distortion and it provides selective harmonic attenuation up to 51 st order.

Amtech offers both 3-phase, 3-wire as well as 3-phase, 4-wire Active Harmonic Filters. Whenever there are single phase non-linear loads like computers, there is an accumulation of triplen harmonic current in neutral. Our 3-phase, 4-wire Active Harmonic Filters are the best choice for such applications.
