EI 57 Transformer

EI 57 Transformer

EI 57 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 57 transformer adopts high-quality silicon steel sheet that features low consumption, high output power, high efficiency, low temperature rise, low noise and stable performance. EI 57 laminated transformers are mostly applied in the switching power supply and main power transformer.

The size of our EI power transformers are from EI-28 to EI-114. We use good silicon sheet and good copper wire.

Description

EI 57 Transformer Specs

EI 57 Transformers are used to spread the signal voltage and signal power.  They can also achieve the impedance matching between circuit and has the isolation effect on DC.
