Product Introduction

SG series dry type transformer is designed to step up/down the voltage as per requirements and widely used in various power supply sites with frequency 50Hz/60Hz and voltage less than 1000VAC.

We have 2 types dry type transformer, one is Auto Transformer, the other one is Isolation Transformer.

NOTE:

Transformer can only convert voltage and CANNOT convert frequency.

Transformer CANNOT convert single phase voltage to 3 phase voltage.

If you want to achieve any of above purposes, please choose our variable voltage and frequency converters.
