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.
