N-73A

P OWE R T RAN S FO R M E R CHASSIS MOUNT : Isolation N-73A Electrical Specifications (@25°C) 1. Maximum Power: 2. Input Voltage: 3. Output Voltage: Series: 230V Parallel: 115V 4. Full Secondary Load: 5. Voltage Regulation: 150 VA 115V@50/60Hz 0.65 Amps RMS 5 % TYP @ full load to no load Description: The N-73A 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. B Safety: 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.
