Schaffner EMC introduces ECOsine® 60 Hz Passive Harmonic Filters which remove harmful harmonics of a pre-determined order, to increase the reliability of supplied power, and thus extend the service life of downstream components. With plug-and-play convenience and more compact dimensions than comparable products, they are easily installed and commissioned. Proven in industrial settings, Schaffner passive harmonic filters are ideal for use with non-linear loads such as motor drives (nominally 5 HP to 250 HP), equipment with front-end 6-pulse rectifiers, fans, pumps, HVAC equipment, DC fast chargers, and more. Passive harmonic filters can improve the productivity by eliminating harmonic-related downtime in varied industrial applications such as manufacturing, water/wastewater treatment, factory automation, mission-critical processes, and more.
Designed to operate at 98% efficiency and installed at the typical three phase voltage of 480 VAC (+/- 10%), at 60 Hz (+/- 1 Hz), these proven products reduce harmonics to 7-10% THDi, and comply with IEEE-519, table 10-3. As not all applications require a THDi of
