Auto Transformers
Auto Transformers
Auto transformers have one winding which acts as the primary and secondary. As a result, when compared to a traditional transformer of equivalent KVA rating, an auto transformer will be smaller, lighter. For voltage ratios that do not exceed about 3:1, an auto transformer is typically a less expensive option than an isolation transformer. If isolation between input and output is not a requirement for your application, an MSI auto transformer is an excellent choice.
