Encapsulated EI41 Silicon Steel Core Power Potting Low Frequency Transformer

Short Description:

SANHE-EI41-005

EI41 is a special reactor for washing machines. Washing machine is used in a relatively humid environment, so moisture-proof is necessary. SH41S-2-001 is installed in a customized shell and is insulated and moisture-proof by potting process. The iron core is fixed by welding process, which can effectively prevent noise and reduce energy loss.

Features

1. The magnetic core is welded to a whole by argon arc welding process
2. Ferrite core of silicon steel has its own air gap
3. Epoxy resin potting process
4. Laser coding

Advantages

1. The iron core welding process ensures good saturation characteristics and reduces noise caused by the iron core resonance
2. Potting with epoxy resin, iron core additionally wrapped with cured resin reduces noise generated by resonance.
3. Low no-load current, low loss
4. Good impedance
