EI 48 transformer is a low frequency transformer. There is no difference between high and low frequency transformers in principle except that different cores are used to achieve different frequency. Low frequency transformers generally use high permeability silicon steel sheet while high frequency transformers ferric core.
EI 48 transformers adopt high-quality silicon steel sheet that features low consumption, high output power, high efficiency, low temperature rise, low noise and stable performance. EI 48 power transformers are mostly applied in the switching power supply and main power transformer.
The sizes of our EI linear power transformers are from EI-28 to EI-114. We use good silicon sheet and good copper wire.
