Description:
Industrial T51U Variable Transformer is an Adjust-A-Volt model T51U variable autotransformer designed to vary AC voltage for electrical testing and development. The unit is documented as a 7.5‑amp variable autotransformer and is listed among other 7.5‑amp models in the Adjust-A-Volt family, alongside Superior Electric 116U and Ohmite VT‑8. With knob‑driven adjustment, it provides a continuously variable output to power or simulate different supply levels for test benches, power supplies, amplifiers, and other equipment under test. Historically, variac-style transformers like the T51U have been used in industrial control and laboratory testing to regulate voltage and facilitate safe ramping of voltages during setup.
