Onduleurs • Redresseurs • Batteries Unitary active filter FAFW series Unitary active filter FAFW series Active filtering and power quality The loads operated by electronic devices are increasingly adopted in more and more industrial and commercial applications such as: Variable Speed Drives, rectifiers, UPS systems, DC power supplies, welding machines, computers, TV, energy efficient lamps, photocopiers. These loads generate waveform distortions that become threats for network and components. In particular voltage and current harmonics, where the latter is the most dangerous, generate a series of problems, like: • Heating cables • Undue tripping of circuit breakers • Blowing of fuses • Overloading of the capacitors and network resonance • Overload on the neutral cable • Premature aging transformers • Malfunction of electronic equipment Features and benefits FAFW is the new generation of active harmonic filters. It reliably mitigates harmonics and compensates voltage dips as well as reactive power. The FAFW analizes network disturbances and provides an opposing compensation current. In doing so, FAFW actively adapts to fluctuations and responds in less than half a millisecond. Its compact dimensions, simple installation, and digital intelligence allow for a quick and straight forward integration in the most diverse applications. • Nominal operating voltage: 380V to 480V • Operating frequency: 47 to 63Hz • Rated compensation current: 30 to 100A at 40°C • Total harmonic current distortion: THID < 5% • Compensation capability odd harmonics: up to the 50th order • Response time: < 300 piS • Protection category: IP20 • Cooling forced air • Overload capability: 2.5xln (rated current) for 10ms • Ambient temperature: 40°C • Altitude: 1000m • Parallel operation: up to 5 filters • Interface: ethernet, RS485, ModBus • Controller: digital with FFT analysis • Current limitation: at nominal current • Current transformers (not included) 100:5 to 50000:5 • Design corresponding to UL508 CE (LVD 2006/95/EC)

Reducing harmonics These products allows to reinject a current corresponding to the total harmonic component (the first order). By this way, the network is traversed by a current equal to the single fundamental component. Applications The applications of the FAFW active filters are very flexible and cover many industrial applications. The FAFW series is an intelligent system to compensate existing electrical installations or the upgrade of a new project with upstream study of the installation. Flere is a list of lists of possible applications with the use of the active filter: • Automotive...
