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 calm your
harmonic waves. Schaffner ecosine filters can be
applied to virtually any kind of power electronics with
front-end six-pulse rectifiers, where harmonic current
distortion needs to be reduced to defined limits.
Typical applications, where the above-mentioned
non-sinusoidal consumers of power can account for a
significant portion of the load, include:

*** *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.
**** Ecosine filters reduce RMS input and peak current by reducing harmonic currents and
**** improving true power factor.
