Single Layer Variautos |
| |
 |
The Variautos offered by Radio Electric is a simple & rugged method to control power, voltage & current. They are designed for heavy duty continuous use. They can provide high current rating, & overload capacity. Radio Electric specilises in design tailor made variautos.They are commonly known as Variac Auto Transformer.
This is a motorized version of Single Layer Variauto. We manufacture it using top quality motors, Micro Switches and rugged construction. The side studs and center shaft are well insulated from each other to avoid completion of magnetic circuit. Models available are 2 Amp, 4 Amp, 6 Amp, ….upto 35 Amp. For Models above 40 Amp, we use side wiping contacts. The commutatorsurface on these coils are machine processed and hence are very even and smooth. This ensures very less torque for the motor enhancing its life.

We specialise in tailor made Variautos depending on the customers exact current requirements. This helps the customer select a proper rating suitable for his application (For eg. If the customer's actual upper limit of current is 20A on a continuous basis and in the Extended Voltage range, then we recommend a higher rating Variautos (say 23A) & then tailor make it for his applications. We also take care to cover up his entire Voltage range (either 0-230 V, 0-260V, 0-110V etc.) We can provide Roller Carbon Brushes fabricated from a Special Electrical grade.
Portable (Enclosed ) Models are available in the entire range.
