P-TN-68X Transformer - Line Isolation, 50 VA, 115V, 435 mA, 2 x 115V
An Isolation Power Transformer for isolating equipment from direct connection to the power line. The transformer is constructed with non-concentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection, under normal or overload conditions, between the primary and secondary windings.
