Often used in step-up or step-down applications, SNC Autotransformers contain only one winding with a portion of the coil serving as both the primary and secondary winding. Different voltages may be obtained by connecting at different points along the winding. Available in Three-Phase and Single-Phase models, SNC Autotransformers are typically used in low voltage situations (600 volts or less) and provide a relatively smaller, lightweight size due to the sharing of the single coil; better voltage stability and greater overload tolerance.
At SNC Manufacturing, we can custom design Autotransformers to meet your exact requirements regarding primary and secondary voltages, power ratings, line frequency, agency approvals, etc. To learn more about how our custom designed Autotransformers can benefit your company’s production process, contact SNC.
