Single phase Isolation Transformer SC3H-K has primary and secondary windings that are physically separated from each other. It allows AC power to be taken from one device and fed into another without electrically connecting the two circuits. The transformer blocks transmission of DC currents from one circuit to the other, but allow AC signals to pass, and also blocks interference caused by ground loops.
