Flyback Transformer, Line Output Transformer (EER, ERL, ETD Core)

EER/ERL/ETD electric transformer adopts cylindrical central pole, which is very easy for wire winding. This design increases the cross section and output power of the winding resistor. Thus it is extremely suitable for making high power main transformer of multiple outputs.
