1KVA isolation transformer 3 phase

1KVA isolation transformer 3 phase

Reasonable price 1KVA isolation transformer for sale to step down any voltage to a usable range output such as 277V to 120V.

This dry-type 3-phase 1KVA isolation transformer provides higher reliability and higher efficiency, making this step-up/step-down transformer ideal for a wide range of applications.

1KVA isolation transformers are manufactured and supplied by Shuogong Power, a leading transformer company in China, and can be customized for various voltages according to your needs.

A 3 phase isolation transformer with a total power of 1KVA can meet the voltage requirements of your equipment.

A 3 phase isolation transformer can step down your input voltage to a usable range output, such as 380V to 200V or 220V output, 270V to 120V output.

We can also customize a 1KVA transformer suitable for your voltage to ensure that your equipment can operate stably and normally.

The role of the three-phase dry type transformer is to step down, and the primary and secondary windings are insulated separately.

1 kVA Isolation Transformer Features:

  • To step down/up the 3 phase voltage 380V to 200V/220V.
  • Primary and secondary windings are separated by aluminium/copper shield.
  • Available in the circuit of AC 50Hz/60Hz.
  • Better protection, high quality workmanship.
  • better security.


Isolation transformers are currently mostly used for purification and maintenance of precision instruments, machine tools, and medical systems, preventing lightning strikes, anti-interference, and stably converting electrical energy.

In medical systems, especially those places where life is critical, such as surgical operating rooms, intensive care units, cardiac operating rooms, etc., the isolation transformer is like a door, connecting the unprotected area of the medical area and the electrical circuit of the protected area. separated.
