In addition to providing real-time mitigation of harmonic currents up to 50th order, ECOsine Active Filters immediately compensate for voltage dips and reactive power surges. Units continuously measure and analyze disturbances in power network and provide exactly opposite compensation current, responding in less than ½ ms. Filters are available in 3-phase/3-wire as well as 3-phase/4-wire configurations for 480 and 400 V grids, respectively, and with rated compensation currents from 30-300 A.

Power Quality Filters help calm harmonic waves.

info@productnews.com (ThomasNet News) — Tue, 22 Jul 2008 07:43:58 -0500

ECOsine(TM) load-applied passive harmonic filters are suited for 3-phase power electronics with 6-pulse rectifier front ends. With total harmonic current distortion of under 5%, products guarantee compliance with IEEE 519 and other international power quality standards. Two ranges are available, one for 380-500 V, 50 Hz grids (FN 3410 series) and one for 440-480 V, 60 Hz systems (FN 3412 series). Plug-and-play concept facilitates installation, wiring, and commissioning.

Active Harmonic Filters dynamically correct harmonic orders.

info@productnews.com (ThomasNet News) — Thu, 22 May 2008 08:02:02 -0500

Using power electronics, StacoSine® Filters monitor non-linear load and dynamically correct every harmonic order from 2nd to 31st. Through injection and cancellation process, sine wave is restored and distortion is reduced to less than 5% THD, meeting IEEE 519 standards. Models are available for 208-480 Vac, 3-phase installations with adaptive system frequency of 45/65 Hz, and 120/240 Vac control power. Rated from 25-200 A, units come in wall mount or freestanding NEMA 1 enclosures.

Low-Jitter Sync Separator works with several video formats.

info@productnews.com (ThomasNet News) — Thu, 11 May 2006 08:09:23 -0500

Available in TSSOP-14 package, LMH1981 multi-format video synchronization separator performs all necessary sync separation to generate low-jitter horizontal and vertical sync signals for NTSC, PAL, SECAM, standard-, and high-definition (HD) video formats. It features timing outputs needed for any video system and accepts bi- and tri-level sync video inputs. Unit also features 50% slicing for separation of signals that vary in amplitude, offset, and noise.

Advanced Harmonic Solutions packages combine VLT® Series variable frequency drives with AHF Series filters. To reduce total harmonic current distortion (THiD) to less than 5%, AHS 005 package matches VLT Series drive with AHF 005 unit. Filters also suppress total harmonic voltage distortion. Also available, AHS 010 package reduces THiD to less than 10%. AHF Series housings integrate into existing panel space and require no balancing or routine maintenance.

HarmonicGuard® Series HG7 Drive-Applied Harmonic Filters limit harmonic distortion at input terminals to levels between 5 and 7% TDD (typ) and consistently hold TDD levels at full and half loads. Product, offered in multiple package options, contains capacitors rated for harmonic duty and fits into motor control centers. Use of reactor technology eliminates nuisance tripping. With HG7, voltage drop on dc bus of variable frequency drive is under 2%.
