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.

Typical applications

Equipment with front-end six-pulse rectifier

Motor drives

Factory automation equipment

Water/wastewater treatment facilities

Fan and pump applications

HVAC installations

Mission-critical processes

DC fast chargers
