Minimum Primary Inductance
Primary Winding Number of Turns
Primary Wire Gauge (Rounded to next smaller
standard AWG value)
Primary Winding Current Capacity (200 < CMA <
500). Warning! Primary circular mils per amp (CMA)
is too high. Decrease transformer size, decrease L,
increase NS, decrease VACmin, increase VOR,
increase KrpKdp.

Secondary Wire Gauge Range (CMA range 500 - 200).
Wire gauge (AWG) is less than 26 AWG. Consider
parallel winding (see AN-18, AN-22).
