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 power transformer for isolating equipment from direct connection to the
power line. This prevents electrical connection under normal or overload conditions
between the primary and secondary windings.
Safety:
BLK
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.
