Auto Transformers

Three phase auto transformers are well suited to applications including industrial automation, industrial machinery and marine applications where there is no requirement for voltage isolation, but some level of voltage adjustment is necessary. They are frequently used as an economical alternative to three phase general purpose distribution transformers to step up or step down voltage to meet specific electrical requirements when load isolation from the supply line is not required. Thus, autotransformer can also be called a step-up or step-down transformer.

PEACO SUPPORT offers a wide range of three phase auto transformers from 10 kVA to 2500 kVA for your customized needs, primary and secondary voltages can be 120V/ 208V/ 220V/ 380V/ 400V/ 440V/ 415V/ 480V AC, etc., such as 220V to 240V, 380V to 415V, 415V to 480V, 440V to 220V, 690V to 400V and more, optional output frequency 50Hz/60Hz, max. working efficiency 90%, protective enclosure IP20, wires can be made of reliable enameled copper or aluminum for options.

Our three-phase autotransformers can save your physical space, manage voltage with high efficiency, reduce your costs and make you have satisfying custom service. A 3 phase autotransformer from peacosupport.com may be a practical, reliable and cost-effective option for you to consider.
