About SBA-Trafo Tech
SBA-Trafo Tech GmbH from Heiligenstadt in Upper Franconia manufactures transformers, power supplies, chokes/inductors and filters as standard products and custom-built units to customer specification. The product portfolio includes mains, control, safety and isolation transformers as well as auto transformers, single- and three-phase mains chokes, DC chokes, commutation chokes, filter circuit chokes for compensation systems from 2.5 to 75 kVAr, discharge chokes, star-point chokes and smoothing chokes as well as filters. User-specific requirements are converted into manufacturing documents using modern calculation software and then manufactured. Low-loss core materials and copper wires are used; vacuum impregnation in drip-proof impregnating resin (at least insulation class F) is standard and reduces noise from remagnetisation processes. Customers include converter and drive technology, reactive power compensation, the general electrical industry, motor drives and fluorescent lamp technology. Transformers can be designed with taps on both the primary and secondary sides.
