Eaton’s Cooper Power Systems utilizes the same manufacturing experience, craftsmanship, and robust designs found in our conventional three-phase transformers to offer Multi-tap transformers for electrical submersible pump (ESP) applications. Our multi-tap transformers step-up the low voltage output from a Variable Speed Drive (VSD) to power your pumps. With 25 different voltage settings in both delta and wye connections, our transformers can meet a wide variety of applications. Multi-tap transformers are available with both mineral oil and Envirotemp™ FR3™ fluid and can be specified as UL® Listed & Labeled.
