2KVA 3 phase autotransformer

2KVA 3 phase autotransformer

The 2KVA 3-phase autotransformer is rated at 2KVA. What it does is step down any input voltage to a usable range output.

For example, 277V to 120V, 480V to 120V, 480V to 240V, 380V to 220V, etc.

Electromagnetic induction is used, the current input is 1.5A, the output is 2.6A/2.8A, and the frequency is 50/60Hz.

2KVA 3 phase autotransformer is available in two materials: copper wire and aluminum wire. And can choose with or without shell.

2KVA autotransformer advantages:

  • The 2KVA three-phase autotransformer has enough power, the wiring is tight and neat, and there is no jumping circle. The coil is made of insulated H-grade enameled wire, with small no-load current and low loss.
  • The 2kVA 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.
