The FN5040/45 sinusoidal output filters reduce the extra losses in AC motors and help to prevent premature failures and expensive downtimes. They are precisely matched to the technical requirements of modern drive systems and are particularly impressive when used with long motor cables.

With the introduction of the FN5040/45, Schaffner, the international leader in the fields of electromagnetic compatibility and power quality, is further expanding its range of products for improving reliability in motor drive technology. The new sinusoidal output filters smooth the modulated output voltage of modern drives and provide the motor with a clean sinusoidal voltage with low residual ripple. This largely prevents premature ageing or destruction of the AC motor due to high dv/dt, over-voltages, bearing currents or overheating due to extra losses. Expensive downtimes are avoided, and premature service or repair is eliminated.

The new filters are available in a compact open frame design (FN5040) or as a user-friendly packaged version (FN5045 – IP20). The cable-shield support brackets integrated into the housing facilitates work for the installer and favours savings of installation time and costs. Easily understood application instructions allow it to be safely used even beyond standard specifications, for motor frequencies up to 200 Hz or motor cable lengths up 2000 meters. Both models are designed for rated currents of 4.5 to 1200 A and for networks up to 3x 500 VAC (+/- 10%). The UL listing is currently in preparation.

Applications in building technology (pumps, fans, HVAC) benefit equally from the use of the new sinusoidal filter, as do industrial applications with very long motor cables or with several motors connected in parallel.

Passive harmonic filters are an excellent tool for improving the compatibility of motor drives with the public power grid. Schaffner extends the popular ECOsine™ product range with filters for 690V systems, supporting a straightforward upgrade from standard motor drives to «low harmonic drives».

With the extension of the ECOsine™ product family, Schaffner, the international leader in the fields of electromagnetic compatibility and power quality, is raising the bar for harmonic mitigation solutions anew. The new passive 690V harmonic filters are an ideal solution for 3-phase equipment with 6-pulse front-end rectifiers, like e.g. variable speed drives or battery chargers.

Frequency inverters for energy efficiency and speed control of electric motors can, in combination with ECOsine™ filters, be utilized as low harmonic drives, causing minimum system perturbation. As a result of the significant reduction in total harmonic current distortion (THID) to typically 5%, ECOsine™ filters can uniquely guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards. Drive and filter combined allow for unconditional use without the need for a costly power quality analysis in each case. The electrical infrastructure is reliably unburdened, transformers are utilized much more effectively, and the failure rate of neighboring electrical consumers is reduced.

The new ECOsine™ filters FN341xHV are rated for 690VAC/50Hz grids like those often used in chemical plants, in oil and gas exploration, or in heavy industry. The filters are available as a standard for diode rectifiers (FN3410HV) and upon request for thyristor rectifiers (FN3411HV). They come in common steps of power rating from 7.5 to 250kW. The compact filters are designed with IP20 rated enclosures, suitable for cabinet integration or for wall mounting in electrical utility rooms.

Barely one year after the introduction of ECOsine™ passive harmonic filters, Schaffner presents the digital solution for the efficient reduction of system perturbations: ECOsine™ Active. Latest generation electronics enable an intelligent and adaptive compensation of harmonic currents with a response time of less than 300 microseconds.

The use of ECOsine™ Active supports the owner in complying with the stringent international harmonics standards as well as with local utility codes. At the same time the electrical infrastructure is unburdened, a potential overheating of transformers, motors, cables etc. is prevented, and the pre-mature wear of electrical equipment is reduced. The improved Power Quality minimizes the risk of downtimes and process interruptions, saves energy and money.

Besides the global or selective mitigation of harmonic currents up to the 50th order ECOsine™ Active is able to perform power factor correction in a targeted manner. In highly dynamic processes like they are found in welding robots, for example, ECOsine™ Active provides the required reactive power within microseconds, faster than traditional automatic cap banks.

ECOsine™ Active is easy to install and intuitive to operate. The compact package of ECOsine™ Active makes its use possible even when space is at a premium. The 50 and 100 Amp filters in IP20 design are ideal for panel integration, so they can, for example, be installed right by the non-linear load. The IP54 rating of the 300A unit provides protection against dust and environmental influences, perfect for harsh industrial applications.

ECOsine™ Active is available in 3-phase/3-wire as well as 3-phase/4-wire configuration for 480V and 400V grids respectively and with rated compensation currents of 30 to 300A. All 3-wire filters are UL listed and therefore ready for the North American market. Building technology and HVAC installations, heavy industry, data and banking centers, UPSs, water/wastewater treatment facilities, or welding equipment can equally benefit from the many advantages of ECOsine™ Active.

The introduction of Schaffner ECOsine™ filters concludes the era of bulky passive harmonic mitigation products. Superior filter topology and advanced temperature management result in high performance filters in a surprisingly compact, lightweight, and contemporary package.

With the introduction of ECOsine™, Schaffner, the international leader in the fields of electromagnetic compatibility and power quality, is raising the bar for harmonic mitigation products. The new load-applied passive harmonic filters represent the ideal solution for three-phase power electronics with 6-pulse rectifier front ends, such as AC and DC motor drives.

.

As a result of the significant reduction in total harmonic current distortion (THID) to <5%, ECOsine™ filters can uniquely guarantee compliance with the toughest requirements of IEEE 519 and other stringent international power quality standards. Rectifier peak and RMS input current are reduced and a pure sine wave is drawn from the grid. The reduction in current consumption for the same power level saves precious energy and helps to make better use of existing electric system capacity. For new installations, the use of ECOsine™ filters even allows electric conductors, fuses, and breakers to be downsized, or enables a greater number of drives to be powered by a given size of distribution transformer.

.

ECOsine™ harmonic filters are available in two ranges: one for 50Hz grids (FN 3410 series) and the other for 60Hz systems (FN 3412 series). They can easily be selected on the basis of the actual input power demand of an individual load or a group of loads. Because of their compact package, they can be installed right inside the electrical cabinet next to the drive. A simple plug-and-play concept allows for quick installation, wiring, and commissioning, without the need for system analysis or the involvement of highly trained specialists.

A standard safety feature continuously monitors filter temperature, controls the internal fans, and provides an NC/C contact for the seamless integration into a machine or system control unit.

.

ECOsine™ FN 3410 filters are designed for 380-500V, 50Hz grids and are available for power ratings from 4 to 160kW. FN 3412 filters are suitable for 440-480V, 60Hz grids with standard ratings ranging from 5 to 250HP. All filters are UL-approved, CE-marked, and RoHS-compliant. As a custom design specialist, Schaffner can always provide solutions beyond standard filter specifications, for higher power ratings, different grid types, or to meet local utility requirements.

Finder has introduced surge protection devices (SPD) designed specifically for photovoltaic (PV) panel installations.  Additions to its popular 7P Series of SPDs, three new Type 2 surge arresters will protect PV systems from the effects of lightning strike and electrical switching transients.  The products are already supporting the company’s own PV panels at its primary manufacturing plant.

Featuring encapsulated spark gap and/or replaceable varistor modules, the three devices protect the more vulnerable DC side of commonly used earth free and mid point earthed PV systems.  The range includes: the 7P.26.9.420, providing 2 varistors and 1 spark gap for 420V DC systems; the 7P.23.9.700, providing 3 varistors for 700V DC systems and the 7P.23.9.000, providing 3 varistors for 1000V DC systems.

Each device integrates both a visual indicator and a signalling contact to warn when a varistor module needs replacing.  Connection to the signalling contact is via a convenient plug-in terminal block.  The SPDs comply with EN 61643-11 standard and can be 35mm rail (EN 60715) mounted.

Finder’s introduction of a range of SPDs tailored to the needs of PV installations comes at a time when UK government Feed-In Tariffs (FITs) appear to have stimulated a step increase in interest in PV system in the country.  The UK is now the fastest growing market for PV solar energy installations, estimated to produce 96MW of electricity in 2010 compared with 6MW in 2009.

At the same time, a prospective revision of the UK wiring regulations, placing far more emphasis on the provision of protection from electrical surges, has meant there is a resurgence of interest in associated products, in particular varistor and spark gap type SPDs.

PV panels at Finder’s prime manufacturing site in Almese near Turin in North West Italy have been producing an output power of 55kW since early 2009, equating to 61,000 kWh/year.  So pleased with the performance, the company has this month commissioned a further 60kW of PV panels, which of course will be protected by the new 7P Series surge arresters.

Constructed using multicrystalline silicon PV modules, Finder’s initial PV system is calculated to have reduced CO2 emissions by about 37 tons/year, achieving annual cost savings of around 11 TOE (tonnes of oil equivalent).
