EI 28 Transformer

Super ei 28 transformer sold to all over the world

There are four main reasons for the noise of switching power transformer: process problem, loop problem, core problem and load problem.

Transformer process problem
Dip paint drying is not in place, leading to the magnetic core is not strong enough to cause mechanical vibration and sound;
The length of the air gap is not suitable, which leads to the instability of the transformer and the noise.
The wire bag is not tightly wound, which may also cause noise;

There is air gap in the magnetic core assembly, which will cause air vibration and sound at high frequency (if the transformer is fully immersed in vacuum, it will generally not make sound).
