Capsulated single-phase Vario® transformer designed and tested according to VDE0570. Designed as a torodial isolating transformer with separate insulated windings and prepared for class II equipment. Degree of protection IP20. The Noratel Vario® transformer is an optimal solution when continuous control of voltage and current is preferable. The construction ensures a clean sine voltage and no radio interference or additional harmonics are generated. Designed for continuous adjustment of alternating voltage and currents, where of safety reasons an isolating transformer with separate windings is required. In addition to standard types, Vario® variable transformers are supplied strictly on customer request.
