NOTES FROM TABLES

A. OCL (primary inductance) and LL (leakage inductance) are measured at the primary

winding. Turns ratio is specified primary: secondary. (CT = Center Tap).

B. To make a 1:1 ratio from a 1:2CT ratio, use one-half of the secondary (2CT) winding.

C. Dual Ratio Transformers — These transformers have tapped secondary windings to

provide two turns ratios (T/R). Use entire primary winding and connect secondary

pins listed below to obtain desired turns ratio:
