5KVA 3 phase autotransformer

5KVA 3 phase autotransformer

5KVA 3 phase step-down autotransformer with affordable price. Rated capacity 5kVA, input voltage 380V , output voltage 220V/200V , frequency 50/60Hz, copper/aluminum wire optional.

Dry-type autotransformer, electromagnetic induction, primary and secondary windings are insulated separately. Can be OEM, can customize any voltage you need, such as 480V to 240V.

The 5kVA 3 phase autotransformer is a dry-type autotransformer. It mainly steps down the three-phase 380V input to 220V/200V output. The applicable frequency is 50Hz/60Hz. It can be self-cooled or air-cooled, and copper wire or aluminum wire can be selected.

Shuogong Power is a leading transformer manufacturer in China, we can also customize three-phase transformers to meet your voltage needs. Here you can get great prices from transformer manufacturers.

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

You can also choose with or without case, we also support OEM customization, let us be your transformer factory.

5KVA 3 phase autotransformer can be used in CNC production equipment, SMT, printing machine, EDM machine, automatic plug-in machine, precision measuring equipment, laser cutting machine, plastic molding machine, medical monitoring system, PCB drilling machine, laboratory equipment, Military Instrumentation Control Center, etc.


The autotransformer is a transformer with only one winding, which is used as a lifting voltage. Compared with the ordinary transformer, the autotransformer of the same capacity is not only smaller in size but also more efficient, especially when the ratio of variation is close to 1, it is especially economical.

Therefore, this advantage is more and more prominent in high-power transmission transformers with similar voltage. Therefore, autotransformer is widely used in many fields, such as large volume, low loss, and low cost, especially in the fields of import and export equipment power supply, high power motor startup, and so on.
