Schaffner EMC’s ECOsine® Active 3420 is a harmonic filter which provides harmonic compensation in real-time for demanding industrial and commercial environments.

With a capacity of 30 to 300A, operating at 200-480VAC (+/- 10%), the connection-ready 3420 (3-wire) cabinet models include forced air cooling and internal liquid cooling (200-300A), for the power electronics. They are capable of supporting large production facilities. Panel mount (30, 50, 100A) and freestanding enclosure design and IP54 (NEMA 12 indoor) protection ensure fast and easy servicing, and a designed service life of up to 100,000 hours ensures long service intervals.

This proven equipment uses digital technology to monitor and dynamically correct harmonics up to the 50th order in less than 300µs eliminating disturbances before they can cause problems. ECOsine® Active Filters compensate for individual disturbance patterns in a targeted manner and automatically adapts to changing network loads.

Up to five units can be installed in parallel to attain optimal results, for a maximum of 1500A harmonic compensation. Filters also provide reactive current support and load balancing. Proven ECOsine® Active 3420 Filters are equally suited for new installations and retrofits. Other configurations are offered in NEMA 1 and NEMA 3R packages, up to 400A, as well as 600/690vac.
