Westek's new MTE AP harmonic filters with adaptive-passive technology are ideal for chillers, fan drives, variable speed compressors, UPS systems, induction heating, and any six-pulse converter application.
The new range of MTE AP series harmonic filters achieve overall harmonic distortion (THID) levels of under eight per cent from zero to 100 per cent of full load. Harmonic distortion is five per cent between 50 to 100 per cent of full load as measured on typical six-pulse converters.
The MTE AP series harmonic filters have an overall harmonic distortion mitigation that is equal or better than costly, complicated 18-pulse drives, according to Westek.
The MTE AP series harmonic filters are highly suited to HVAC applications as well as other applications with large load variations and meet Australian standard AS/NZS 61000.3.6.
The standard limits total harmonic voltage distortion (TDHV) to eight per cent maximum with very tight limits on specific harmonics such as the third, fifth, seventh, etc.
Unlike active filters, the MTE AP range is extremely rugged, containing only passive components (capacitors, chokes) and no resistors. Side access to the filters is unhindered.
They are convection cooled and high current capacitors are employed, while the enclosures are mathematically modelled using proprietary software to yield optimum convection cooling.
The MTE AP series harmonic filters have high power factor and are suitable for generator drives, thus providing additional benefits for mission-critical applications.
They are available as 480 volt, 50 Hz filters, and in current ratings from six amps to 1200 amps.
