Harmonic Filters
Harmonic distortion leads to overheating, malfunctions, and increased wear on electrical equipment. Filtering these harmonics is key to protecting your system and staying compliant with grid codes. We offer a full range of harmonic filters using different technologies and working on different frequency ranges. All of them are designed to match your voltage level, application, and budget.
Active Filters
Eluminate active filters use advanced SiC MOSFET technology to deliver high-efficiency harmonic mitigation, both for symmetrical and unsymmetrical and high-order loads, for a wide range of voltage levels. Compact and modular, they’re ideal for demanding industrial environments where space and stability matter.
We can supply integrated cabinets combining multiple filters, power factor correction, phase balancing, and resonance mitigation—tailored to your site. These filters dynamically adapt to changing conditions, making them ideal for fluctuating loads and large installations
Passive Filters
Our passive filters use a 2-stage topology to reduce THDi below 5–8%, with smooth damping up to the 200th harmonic. With 99.5% efficiency and no need for drive de-rating, they offer reliable performance in a compact, forced-air-cooled design. They’re a cost-effective option for fixed loads such as motor drives, where harmonic sources are known and stable. We also offer passive solutions specifically for higher-order harmonics above the 50th—where standard filters often fall short. We’ll help you find the right mix.
Hybrid Filters
Hybrid filters combine the strengths of both active and passive filters, delivering effective harmonic mitigation for symmetrical loads with a lower total system cost. It’s a smart balance of performance, reliability, and value.
Supraharmonic Filters and Surge Protection
Supraharmonic voltage spikes and transients can silently damage sensitive electronics, transformers, and control systems. Our SineTamer® supraharmonic filters act as a protective barrier, eliminating disturbances before they cause problems.
They also include surge protection, saving your sensitive equipment from lightning strikes. If your communication or automation systems behave unpredictably, supraharmonic distortion could be to blame. SineTamer® cleans the signal, restoring stability and uptime.
