MTE Matrix Filters solve the problem of harmonic distortion on virtually any kind of six pulse rectifier. These power supplies are commonly found in three phase electronic equipment such as adjustable speed motor drives, welders, battery chargers, servo drives and other equipment. Harmonics are a problem Harmonic distortion has become an increasing concern for facility managers, users of automation equipment and specifying engineers alike. Harmonics not only waste energy, but they reduce equipment life, electrical system reliability, system efficiency and equipment productivity. Guaranteed results Unlike other harmonic filter technologies, the performance of MTE Matrix Harmonic Filters is guaranteed! On AC variable frequency, variable torque drive applications (fans & pumps), Matrix filters will meet the guaranteed maximum levels of THID (total harmonic current distortion) all the way from no load to full load. Additionally, Matrix filters will not cause power system resonance nor attract harmonics from other non-linear loads. No system analysis is required to select and apply Matrix Filters.
