Features and Benefits

Schaffner ecosine harmonic filters represent an economical solution to the challenge of load-applied harmonics mitigation in three-phase power systems. With a plug-and-play approach and more compact dimensions than comparable products, they can be quickly installed and easily commissioned. They increase the reliability and service life of electric installations, help utilize electric sytem capacity better, and are the key to meet Power Quality standards such as IEEE 519. Ecosine filters reshape your distorted current back to the desired sinusoidal waveform. Schaffner ecosine filters can be applied to virtually any kind of power electronics with front-end six-pulse rectifiers, 3-phase diode or thyristor bridges, where harmonic current distortion needs to be reduced to defined limits.

* System requirements: THDv <2%, line voltage unbalance <1% Note: performance specifications in this brochure refer to six-pulse diode rectifiers. SCR rectifier front-ends will produce different results, dependent upon the firing angle of the thyristors. ** External UL-rated fuses required. Please consult the user manual. *** Please check the inlet air flow required for cooling table further in this document and the user manual. **** Iderated = Inominal*SQRT((Tmax-Tamb)/(Tmax-Tnominal)) = Inominal*SQRT((70°C-Tamb)/30°C)
