1KVA three phase autotransformer manufacturers sell online.
The 1KVA 3 phase autotransformer has a rated capacity of 1kVA and can reduce any voltage to the required range, such as reducing the input voltage 380V to 220V or 200V.
1KVA 3 phase autotransformer input current 8A, output voltage 220V or 200V, output current 2.6A or 2.8A, frequency 50/60Hz.
The function of the dry-type three-phase autotransformer is to step down, and the primary and secondary windings are insulated separately.

1KVA autotransformer advantages:
- 1KVA three-phase autotransformer power is sufficient. The coil is made of insulated H-grade enameled wire, with small no-load current and low loss.
- 1kVA dry-type autotransformer has built-in silicon steel sheet, which has good magnetic flux performance, high heat dissipation coefficient and low magnetic loss.
- The autotransformer adopts electrophoresis technology fixture, with no burr on the edge, rounded corners to prevent collision and not easy to corrode.
- Tin-plated copper tube terminals and rail-type wiring ports are convenient for wiring and ensure that the power-on overload capacity is improved to the extreme.
