P-TN-51XTransformer - Isolation, 35 VA, 115V, 300 mA, 1 x 115V

35VA chassis mount Power Transformer for isolating equipment from direct connection to the power line. It 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. These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B insulation system.
