Product Profile of Variable Auto Transformer

Purevolt Products [P] Limited manufactures Variable Auto Transformer. Purevolt Products [P] Limited is an ISO 9001: 2000 certified company. Variable Auto Transformer is highly useful and effective device for step less, break less and have continuous control of A.C voltage.

Variable Auto Transformer has the following features:

• Simple & rugged in construction

• Good Regulation- Voltage drop on load is low

• Output voltage variation on no-load and even on load is effortless, smooth, continuous, break less and linearly proportional to angular rotation

• High Efficiency- No load losses and load losses are low

• Negligible waveform and power factor distortion due to simple transformer action

• Excellent short time overload capacity

• Easy for remote operation with the help of motor drive

• Wide range of models
Technical Specifications of Variable Auto Transformer are:
