Jefferson Powerformer Buck-Boost Transformers Use the inherent flexibility and versatility of Jefferson's buck-boost transformers for a variety of applications. They reduce (buck) or raise (boost) line voltages from five percent to 20 percent and come in a wide range of KVA sizes and input/output voltages. With four windings, they're highly adaptable and can be configured in any number of voltage combinations for your application. In fact, our most popular group with a 12 volt secondary can even be used for low voltage lighting applications.
