Step-Up/Step-Down Autotransformer -- F-302U
from Triad Magnetics

Description. Triad autotransformers are single winding single phase transformers in which the primary coil is a fraction of the entire winding for voltage step-up or the secondary coil is a fraction of the entire winding for voltage step-down. In ordinary double wound power transformers, the primary... [See More]
