Radiotone Double Layer Variable Autotransformer

Radio Electric Pvt. Ltd. Is a pioneer in India in the field of Double Layer Variable Autotransformer with the brand Radiotone. The Radiotone Double Layer (DL) Variable Autotransformer (colloquially known as Variac) was specially designed in 1982, for the Servo Controlled Voltage Stabilizer Industry. Since then we have supplied thousands of Radiotone Double Layer Variable Autotransformer to the Industry.

Radiotone Double Layer (DL) Variable Autotransformer (colloquially known as Variac) combines the functions of Variable Autotransformer and Buck Boost Transformer for the required range of Voltage. It makes the whole unit very compact, thus reducing the size of Servo Stabilizer Cabinet. It increases the productivity on Shop floor as the assembly & wiring are considerably reduced. We can tailor make Radiotone Double Layer (DL) Variable Autotransformer to suit customer’s specific voltage range (i.e. 180V - 260V or 85 V - 135 V ) as required.

RADIOTONE DL Variable Autotransformer :

This Variable Autotransformer can substitute the combination of Variable Autotransformer & Buck-boost in Servo Controlled Voltage Stabilizer.

Standard Range :-

· 1 DL miniature size
· 2 ADL to 22 ADL at 230V.
· Range: 165V to 275V.
· It is advisable to use a MCB at I/P.

Radiotone DL (R) Variable Autotransformer

This is an electrically reverse type DL Variable Autotransformer as shown in the figure & is available in standard range of 2A DL(R) to 15A DL (R). This is a fail-safe design and does not need a MCB at I/P
