3KVA isolation transformer 3 phase step down

3KVA isolation transformer is a 3-phase step-down transformer whose main function is to step down the input voltage to the usable range output.

3KVA 3 phase isolation transformer is a dry-type transformer, which has the characteristics of strong anti-interference, stable performance and good safety, and can effectively protect the voltage of your equipment.

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

This 3KVA isolation transformer is suitable for any voltage. The main function is to step down the input voltage to the usable range for output, such as step down the input voltage 480V to 120V, step down 277V to 120V, step down 380V to 220V, etc.

3KVA three-phase isolation transformer is a three-phase dry-type transformer with economical price, the primary and secondary windings are insulated separately.
