N-77U

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 a power transformer for isolating equipment from direct connection to the powerline. The primary and secondary coils are concentrically wound providing excellent magnetic coupling. Having good magnetic coupling between windings helps reduce leakage flux and phase shift. BLK N-77U Safety: BLK/YEL BLK/GRN 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.
