Product details

The SGB (DGB) series three-phase (single-phase) dry-type isolation transformer is a multi coil (double coil and above) structure transformer. The primary and secondary windings are insulated from each other, and its transformation ratio can be fixed or tapped. It can use the principle of electromagnetic induction to increase or decrease voltage. Isolation transformers can not only change the voltage, but also electrically isolate the input winding and output winding from each other to avoid the danger of simultaneously touching live objects (or metal parts that may be charged due to insulation damage) and ground; In addition, isolation transformers also have a certain function of suppressing various interferences and filtering out harmonics.

The main function of an isolation transformer is to:

Electrical safety isolation
Change voltage level
Overcoming center drift and improving power imbalance
Surge protection and filtering function
