P OWE R T RAN S FO R M E R CHASSIS MOUNT : Isolation N-66A Electrical Specifications (@25°C) 1. Maximum Power: 250 VA 2. Input Voltage: Parallel: 115V@50/60Hz Series:230V@50/60Hz 3. Output Voltage: 115V + 5% 4. Full Secondary Load: 2.17 Amps RMS 5. Voltage Regulation: 5 % TYP @ full load to no load Description: The N-66A is power transformer for isolating equipment from direct connection to the power line. It is constructed with nonconcentrically 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. A Safety: PRIMARY 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.
