Passive Harmonic Filters operate at 99% efficiency.

Press Release Summary:

Available in NEMA 1 and 3R enclosures, ECOsine® FN3415 Filters benefit electrical systems by limiting amplitude of current harmonics, minimizing losses, and maximizing efficiency. Devices are installed at typical 3-phase voltage of 480 Vac (±10%) or 600 Vac (±10%) at 60 Hz (±1 Hz). TDD and THDI performance at full, light, and no-load conditions is ≤5%, while THDv ratings are ≤3%. Filters are suited for virtually any kind of power electronics with front end 6-pulse rectifiers.

Schaffner Expands ECOsine® Passive Harmonic Filter Line

Model FN3415 Is Ideal for 60Hz, 480 & 600 VAC Applications

(Edison, NJ) -- Schaffner EMC introduces the FN3415, the newest addition to the ECOsine® family of Passive Harmonic Filters, for 60 Hz, 480 or 600 VAC applications.  Available in various NEMA enclosures, they are easily installed and commissioned, providing immediate benefit to the electrical system by limiting the amplitude of the current harmonics, reducing losses, and allowing equipment to operate more efficiently with a longer service life.  Proven in industrial settings, Schaffner passive harmonic filters are ideal for use with virtually any kind of power electronics with front end six-pulse rectifiers including non-linear loads such as motor drives/VFDs, factory automation equipment, fans, pumps, chillers and other HVAC equipment, DC fast chargers, mission critical systems/datacenters, water/wastewater processing equipment, oil and gas drilling and more.

Designed to operate at 99% efficiency and installed at the typical three phase voltage of 480 VAC (+/- 10%), or 600 VAC (+/- 10%) at 60 Hz (+/- 1 Hz), these proven products reduce harmonics, to meet IEEE-519 (2014).  TDD and THDI performance at full, light and no-load conditions is less than or equal to 5%, while THDv ratings are less than or equal to 3%.  Schaffner also offers more basic designs for installations with less critical harmonic mitigation needs.

NEMA 1 and NEMA 3R enclosures, wall-mounted or free-standing, are standard.  Other ratings are available.  All FN3415 models are UL and cUL listed.  They are ideal for new installations and retrofits. 

Harmonics – A Silent But Deadly Problem

Harmonics are generated by nonlinear components in electrical systems, which distort the sine wave.  Increasing usage of power electronics causes a corresponding increase in voltage distortion, or harmonics.  Common electrical components like motors, pumps, fans, automation equipment, DC fast chargers, equipment with front-end six-pulse rectifiers, and more, all introduce harmonics into the electrical system.  When harmonics are present they can manifest themselves with short-term and long-term consequences.  High harmonic distortion can cause failures or malfunctions of electrical devices.  Harmonics also cause a temperature rise in the electrical network and in equipment, resulting in losses and shorter service life.  Passive harmonic filter, like the ECOsine® Passive, when tuned to the offending harmonic order, corrects the sine wave, before the harmonics can cause any damage to the electrical system or equipment. 

Schaffner EMC, with US operations headquartered in Edison, NJ, is part of The Schaffner Group — a worldwide leader in the fields of electro-magnetic compatibility (EMC), power quality (PQ) and engineered transformers.  From a global innovation and development center in Luterbach, Switzerland, the company develops leading edge products which are manufactured in facilities worldwide.  Their PQ product line includes active and passive harmonic filters, along with sine wave filters, which allow the efficient and reliable operation of electrical and electronic equipment and systems.  For additional information visit, write to them at Schaffner EMC Inc., 52 Mayfield Avenue, Edison, NJ, 08837, or call (800) 367-5566 ext 276.
