1.4.2 Main Transformer Specification
Windings All copper.
Magnetics Grain orientated, M6 grade, stress relieved transformer steel is utilized for
minimum losses and maximum efficiency.
Insulation Class (N) 200 all sizes.
Shielding Multiple triple copper shield to minimize interwinding capacitance, transient,
and noise coupling between primary and secondary windings.
Cooling Convection, operating temp is 130 degrees Celsius maximum rise
above ambient.
