Notes : 1) Overvoltage Category III, Pollution Degree 2
2) Primary 1 is between A and B, primary 2 is between C and D
3) Excludes the electrical offset
4) Refer to derating curves in the technical file to avoid excessive core
heating at high frequency
5) Please consult characterisation report for more technical details and
application advice.
