Schaffner Expands ECOsine® Passive Harmonic Filter Line
Edison, NJ — Schaffner EMC has introduced the FN3415, the latest addition to its ECOsine® family of passive harmonic filters for 60 Hz, 480 or 600 VAC applications. Available in various NEMA enclo- sures, they are easily installed and benefit the electrical system by limit- ing the amplitude of the current harmonics, reducing losses, and allowing equipment to operate more efficiently with a longer service life. Proven in industrial settings, the passive harmonic fil- ters are useable with virtually any kind of power electronics with front-end, six-pulse rectifiers, including non-linear loads such as motor drives and VFDs, factory automation equipment, fans, pumps, chillers and other HVAC equipment, DC fast chargers, mission critical systems and datacenters, water and wastewater processing equipment, and oil and gas drilling. Designed to operate at 99 per-
RoHS
cent efficiency and installed at the typical three phase voltage of 480 or 600 VAC (±10 percent) at 60 Hz (±1 Hz), the 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 percent, while THDv rat- ings are less than or equal to 3 per- cent. The company also offers more basic designs for installations with less-critical harmonic mitigation needs. NEMA 1 and NEMA 3R enclo- sures, wall-mounted or free-stand- ing, are standard. Other ratings are available. All FN3415 models are UL and cUL listed.
Harmonics are generated by
non-linear components in electrical systems, which distort sine waves. 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, equip- ment with front-end six-pulse recti- fiers, and more, all introduce har- monics into the electrical system. When harmonics are present they can manifest themselves with both short-term and long-term conse- quences. High harmonic distortion can cause the failure or malfunction of electrical devices. Harmonics also cause a temperature rise in electrical networks and in equipment, result- ing in losses and shorter service life. Passive harmonic filters, like the ECOsine® Passive, when tuned to the offending harmonic order, corrects the sine wave before the harmonics can cause any damage to the electri-
cal system or equipment. Contact: Schaffner EMC, Inc.,

Tebis America Updates CAD Software
Troy, MI — Tebis America, a soft- ware company specializing in CAD/CAM systems for design and manufacturing, has
introduced
Version 4.0 of its Tebis design soft- ware. The new release has been visu- ally redesigned, with UI improve- ments and intuitive access to func- tions through icons and more feed- back to the operator. The Version 4.0 release is espe-
cially suited to components with steep cavities and can also be used effectively for hard materials. It real- izes its full potential in combination with high performance cutters (HPC). In adaptive roughing, the path layout is automatically adapted to the geometry without full-width machining. The large depth-of-cut and smaller lateral step-over ensure efficient manufacturing. The software’s new interface
provides users with considerably more feedback than the previous ver- sion. During offscreen calculation Tebis allows up to six NC calcula- tions to be initiated in multiple open CAD files. Programmers now have an overview of the status of the processes in the files with the progress indicator that covers multi- ple parts. Any errors that occur dur- ing the calculations are communicat- ed immediately to the user, and across multiple files. To meet the demands of a
diverse manufacturing industry, the company offers multiple industry-
specific bundles along with 56 differ- ent additional combination possibili- ties. All with the intent to fit the size and ability of a user, these scalable levels, labeled Standard, Pro and
Tebis Version 4.0.
Premium, create a fit for a manufac- turer’s CAD/CAM/NC process chain. The Standard version is an afford- able, entry-level solution that fits most shops. Companies that have standard three-axis NC milling machines and low-end CAD/CAM products will be able to acquire the power of Tebis at similar pricing. The Pro version is useful for mid-sized companies that have multi-axis machines and demand a higher level of automation for their operation. The Premium package delivers the complete solution package making the highest automation and strate-
gies available. Contact: Tebis America, 400 E
