The REVCON RHF-Active Series is a state-of-the-art line of active harmonic filters designed to combat mains distortion caused by non-linear electrical loads. Unlike conventional filters that rely on outdated IGBT topologies and passive tuned circuits, the RHF-Active Series utilizes advanced Silicon Carbide (SiC) power modules for superior performance, lower losses, and compact design.

Operating on a unique principle, the RHF-Active injects harmonics of inverse polarity directly into the system, effectively cancelling out unwanted harmonics drawn from the supply. This parallel compensation method allows for real-time dynamic filtering, ensuring your system operates within the strictest THDi requirements.

The RHF-Active filters are ideal for a wide range of applications, from direct integration with variable frequency drives (VFD) to centralized compensation at distribution panels. Common use cases include data centers, HVAC systems (ventilators, compressors, pumps), and industrial environments with both symmetrical (3P3W) and asymmetrical (3P4W) loads.

With multi-function capability, including harmonic mitigation, power factor correction, and load balancing, the RHF-Active Series offers a scalable and efficient solution for modern electrical networks.
