P OWER TRANS FOR MER CHASSIS MOUNT : Isolation N-257MG Electrical Specifications (@25°C) 1. Maximum Power: 500 VA 2. Input Voltage: 230 V, 50 / 60 Hz 3. Output Voltage: 115V + 5% 4. Full Secondary Load: 4.35 Amps RMS 5. Voltage Regulation: 5 % TYP @ full load to no load Description: The N-257MG 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. 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.
