Product Introduction:

Dry-type isolation transformers are primarily intended to electrically insulate the primary and secondary windings, so the most basic requirement for them is to ensure insulation performance of the primary winding. Voltage transformation is not their primary task, and most isolation transformers do not perform voltage transformation, meaning that the number of turns in the primary and secondary windings are equal. Their safety lies in the fact that the secondary winding is not grounded, so that there is no electrical path between the output and ground. This means that a person touching the output with only one end will not be electrically shocked. Additionally, static electricity isolation prevents static interference and breakdown from occurring during secondary operation.

Product Features:

1.High isolation.

2.N-G performs well.

3.High common mode interference suppression.

4."△" to "Y"/" Y" to "△"conversion is convenient.

5.Customized for special applications.
