P OWE R T RAN S FO R M E R CHASSIS MOUNT : Isolation N-77U Electrical Specifications (@25°C) 1. Maximum Power: 2. Input Voltage: 3. Output Voltage: 5. Voltage Regulation: 100 VA Series: 230VAC, 50/60Hz; Parallel: 115V, 50/60Hz 115V @ Full Secondary Load: 0.86Amps RMS 9% TYP @ full load to no load Description: The N-77U is power transformer for isolating equipment from direct connection to the power line. This prevents electrical connection under normal or overload conditions between the primary and secondary windings. Safety: BLK These units are designed with 1500V isolation between winding to winding and between winding and core. Materials and construction are rated for Class B (130°C) insulation system.
