    About Transformers
    industrial info icon

    Compare transformer features and learn about voltages. Then, choose the transformer that's right for your application.

    Enclosed Step-Up/Step-Down-Voltage Transformers

    Improve the efficiency of your equipment—wire these transformers to step your input voltage up or down by as much as 20%. Choose an input/output voltage combination that comes closest to matching your application, then choose the output power (in VA) of the equipment you want to operate. You probably won’t find the exact value you need; choose the next highest rating.
    Note: Transformers are labeled with a pre-wired output power and pre-wired primary and secondary voltages. Single-phase transformers are labeled as 120/240V AC primary voltage and 12/24V AC secondary voltage. Three-phase transformers are labeled as 120/240V AC primary voltage and 16/32V AC secondary voltage.
