Available from Westek Electronics , the new, ECOSine Active 60 Amp filter from Schaffner is specifically designed for harmonics mitigation in commercial and industrial electrical installations where loading can change rapidly, and in an unpredictable manner.
For example, the ECOSine Active 60 Amp filter can ‘unload’ not only the neutral from unwanted triplen harmonics but also reduce phase current in risers, thus significantly reducing energy loss in conductors and in upstream gear including switchboards and transformers. The ECOSine Active 60 Amp filter is ideally suited to major installations such as hospitals, banks and other financial institutions where large IT loads can be predicted. The Amp filter also sharply decreases voltage distortion from the main reticulation, providing far more reliable operation of voltage-sensitive loads including medical electronics and other hospital equipment.
The ECOSine Active 60 Amp filter absorbs harmonic components originating from the connected loads, in the three phases and the neutral. Absorbing harmonics in the neutral is essential in that generally loads are not balanced or vary over time, thus causing not only a neutral fundamental power frequency component but also third harmonic as well as higher harmonic components. The ECOSine Active 60 Amp filter is therefore suited for installation at the sub-distribution board level, as well as for individual loads.
The Amp filter employs a very fast harmonic absorption algorithm that is capable of responding to load variations and harmonics to the 50th order, within 300 microseconds. The Schaffner ECOSine Active filters provide a tailored solution to harmonics compensation permitting corrective current for specified harmonics.
The ECOSine Active 60 Amp filter can be employed in 4-wire circuits with line voltages from 380 to 480 Volts, and frequencies of 47 to 63 Hz. Total Harmonic Current Distortion (THID) can be reduced to 5%.
