A2 Merus Power Active Harmonic Filter

Merus active harmonic filters is the power industry’s go-to solution for real-time compensation of an electrical system’s harmonic distortion, brought about by non-linear loads and rectified loads.  Harmonic correction is in compliance to the IEEE 519, G5/4 and other power quality standards. Merus active harmonic filters is a versatile solution, easily tailored to deliver power factor improvement, voltage variation control, flicker mitigation and load balancing functionality.

The Merus A2-series active harmonic filters are designed for light to heavy industrial and commercial facilities with voltage level up to 480V.  Merus M-series active harmonic filters are customized for demanding applications and are available from 480V up to 1000V. Equipped with state-of-the-art monitoring and reporting functionality, the robust Merus active filters operate in harsh environments and are easily scalable.
