Schaffner RWK 3044 and RWK 3062 series 3-phase AC line reactors
Schaffner is unveiling the new AC line reactor series RWK 3044 and RWK 3062
Schaffner is unveiling the new AC line reactor series RWK 3044 and RWK 3062.
RWK 3044 and RWK 3062 are designed for 400 VAC and 690 VAC network, and providing impedance of 4% and 2%, respectively. The Schaffner PQ product portfolio is once again expanded by introducing the brand new 2% 690 VAC line reactor RWK 3062. This further strengthens the unparalleled one-stop-shop approach for Schaffner partners and customers.
AC line reactors are an economical solution to reduce harmonic currents, to limit inrush currents and to protect variable frequency drives (VFD). An overall improvement of the true power factor and the quality of the input current waveform can be achieved. Furthermore, by applying RWK 3044 and RWK 3062 severe harming phenomena such as commutation notches are reduced to comply with the recommended notch depth and notch area as per IEEE519-2014 (C.1). Thus, with the installation of the new AC line reactors, the electrical infrastructure is unburdened, and its utilization is much more efficient and reliable. Furthermore, the service life cycle of electrical equipment is extended, and energy costs are reduced.
With Schaffner’s expertise in the field of inductor design as well as broad experience in power quality and various reactor applications, RWK 3044 and RWK 3062 are suitable for the most demanding industrial environments but still being very compact. Up to 50% weight reduction in comparison to former generations of AC line reactors could be achieved.
AC line reactors RWK 3044 are rated for 380 VAC to 415 VAC, with current ratings from 2 A to 1000 A, while RWK 3062 are rated for 500 VAC to 690 VAC with current rating from 1.5 A to 870 A. They are available as open frame product (IP 00) and can be operated at ambient temperature
of 45°C without derating and up to 100°C with derating. All RWK 3044 and RWK 3062 reactors are CE-marked and RoHS compliant. The new reactors are easy to install and maintain and are fully supported in Schaffner’s well known power quality simulator Schaffner PQS3 for a quick and accurate performance check.
As power quality solution provider, Schaffner offers customer-tailored solutions by combining reactors with passive and/or active harmonic filters. This will ensure dedicated harmonic mitigation solutions and improve system efficiency and reliability.
