High Voltage Transformer (EFD Core)

Southern Group produced EFD transformer adopts flat type ferrite core. It has features of low magnetic leakage, low loss, wide working frequency, strong anti-interference ability, etc. So it is widely used in switching power supply, LED power supply, adapter, charger and so on.
