    Enclosed Voltage-Stabilizing Transformers

    Protect sensitive equipment from electromagnetic interference and maintain power during three-millisecond power dips. These transformers also isolate output and input voltage (output regulation is ±3% with input voltage fluctuations from +10% to -20%). When wired for constant voltage, transformers filter out voltage spikes and electrical noise.

    Panel-Mount Variable-Voltage Transformers

    Permanently install these transformers in panels. Turn the dial to adjust the voltage you need within a given range. Also known as variacs, they are often used in laboratories to vary power, heat, speed, or force. When wired for constant voltage, transformers filter out voltage spikes and electrical noise.
