ISOLATION TRANSFORMER

TEKSAI Isolation Transformer is Designed & Constructed with Primary and Secondary winding closely wrapped about the same ferrous core. A single faraday shield is used between the Primary and Secondary windings. Isolation Transformers block transmission of DC signals from one circuit to the other, but allow AC signals to pass. They also block interference caused by ground loops.
