Electrical Specifications (@25°C)

1. Maximum Power:

150 VA

2. Input Voltage:

115V@50/60Hz

3. Output Voltage:

Series: 230V

Parallel: 115V

4. Full Secondary Load:

0.65 Amps RMS

Description:

The N-73A 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.

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.
