6KVA isolation transformer 3 phase step down

6KVA isolation transformer 3 phase step down

Reasonably priced 6KVA 3-phase isolation transformer for sale.

This 3-phase isolation transformer with a total power of 6KVA is a dry-type air-cooled self-cooling transformer. It is suitable for AC 50Hz/60Hz circuits. It can convert a primary voltage of 480V to a secondary voltage of 380V for output. It has a long life and high efficiency.

High-quality 6KVA 3-phase isolation transformers are manufactured and supplied by Shuogong Power, a leading transformer company in China.

Isolation transformers have the advantages of good safety, low noise and good stability, and can meet various voltage requirements of your equipment.

This 6KVA isolation transformer is a dry-type transformer, and its main function is to step down to reduce the input voltage to the usable range output, for example, step down 380V to 200V/220V, step down 480V to 380V, etc.

We can also customize 3-phase isolation transformers to suit your voltage.

We provide a one-year free warranty service for all transformers.
