Transformer IE core square dimension
Clik on region from which you want help or see below.
Power of transformer is calculating from square of it's EI core.
Dimensions for height and width are taken from core intersection,
on left image is with white square marked section which is used for
measurement.
There is shown only "W" and "U" profile of EI core.
Height and Width of core intersection
Use middle for "W" profiled or one of side in "U" profiled intersection
to measurement height and width.
Write measured data in milimeters and try to be precise in measurement,
it is big difference in one milimeter.
Maximum power of core
While you change size of intersection, maximum power of core which it can
provide is displayed.
If your request for output power is bigger than here displayed, background
color will change from green to red.
You can change size of intersection and when size provide bigger power of
requested it become green again.
Green background color indicates that you can with current calculations build
transformer.
Oposite of that, red color indicates that you can't use this size of
intersection for building transformer.
