Active Harmonic Filters
Shaping electrical power!
The new modular Schaffner ECOsine™ series offers fitted and economical
solutions for the most demanding harmonic
mitigation challenges with any kind of non-linear
load involved. Ecosine active sync filter series
provides a solution concept which is modular,
compact and can be used as stand-alone modules or
as system solution. The optional sync module offers a
smart load Management of the filter’s usage and
allows redundancy which guarantees a smart power
quality solution in the era of Industry 4.0. We provide active harmonic filters with excellent
performance in solving power quality problems
focusing on customer needs and application
demands for cleaner and smarter energy.
