500 VA
2. Input Voltage:
230 V, 50 / 60 Hz
3. Output Voltage:
115V + 5%
4. Full Secondary Load: 4.35 Amps RMS

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.
