Radiotone High Current Air Cooled (Three Phase) Variable Autotransformer

Open Type Motorized :

This is a High Current Air Cooled Three Phase Variable Autotransformer (colloquially known as Variac) with open construction. The motorized assembly has common rail at the bottom and is geared on top. Connections are provided on tinned copper bus bar. Forced Air cooling is provided on each coil for long life.

We can supply 160A /200A /240A /300A /400A /600A /800A /1200A

Enclosed Type Motorized :

This is a 300A High Current Air Cooled Three Phase Variable Autotransformer (colloquially known as Variac) of enclosed type. It is suitable for testing application.

This model has a facility for individual phase voltage setting as well as common (for all three) phase voltage setting. This facility allows ON LINE correction / balancing of individual phase voltages by using Raise/Lower buttons provided for each phase.
