Examples
Here are some calculations what I made and from what I build transformers.
- Transformer: 220V - 2x27V 8A
Input voltage 220 Volts.
Output voltage two times by 27 Volts 8 Ampers, simetric for amplifire.
EI core intersection square is 50 by 48 milimeters.
Calculated values:
- Input 220 Volts 2.258 Ampers
- 443 coils of 1.05 milimeters wire thickness
Here I use wire of 1 milimeter, because core is big enough and warming at that
thickness is low. True reason is that I didn't have wire of 1.05 milimeters.
- Output 2 x 27 Volts 8 Ampers
- 2 x 54 coils of 1.98 milimeters round to 2 milimeters.
In assembling I use for output two wires of 2 milimeters at one quill.
Begining point of two wires are joined and this is output ground, end point is
two outputs of 27 Volts.
I build that transformer and it works perfect.
