Our 3-Phase units are designed to meet UL insulation system and UL 1561 Standard Construction requirements and are fully customizable to meet application specific requirements. V&F has experience with both copper and aluminum conductors in both open core and coil and standard/custom enclosed configurations. V&F’s powerful engineering team has the expertise and experience to address even the most complex application requirements whether it be harmonic mitigation or meeting specific electrical tolerances. V&F’s computer aided design systems will not only allow V&F to develop an optimal design from a construction and cost standpoint but also allows our engineering team the ability to “virtually prototype” 3-Phase magnetics to predict performance in a customer’s application.
