Auto Transformer

Beta power has been manufacturing & Supplying Variacs for the past ten years and has a strong support for OE buyers. Many valued customers have considered it fit to clarify our products as "top of the line". It has full technical competency in handling all the technical requirements of clients.

It is well supported by the state of the art winding machinery to give a consistent & accurate job. Needless to mention, a strong backup team with years of experience has put-high reliability in the product. Our Motto is "Customers Satisfaction leads to Good Quality" and our learning curve never ends. We are presently exporting our products to UAE, Tanzania.


We are equipped wi th allTesting Equipmentsto ensure the quality ofVariac Electricals.The company testing section has Testing Panel Board, HV Kit, Megere Test, Oscilloscope, Power Meter, Watts meter etc., which all are calibrated every year as perISOnorms.

FOr Servo controlled Voltage Stabilizers double layer dimmers can be used without separate Buck-Boost Transformers so as to achive cost efficiency and compactness. These are standardised viz. 1kva, 2kva, 3kva & 5kva suitable for input range : 170 to 270v and output : 230v

We are looking for queries for Beta power Equipment from Tamil Nadu, Kerala, Karnataka & Andhra Pradesh,allover india and exports.

Beta power has been highly engaged in manufacturing and Supplying Auto Transformer, which scans at one stroke, all the windings of a transformer and tests as per definition of test procedure. The test procedure can be pre-programmed and stored under user friendly menu driven software . It uses an advanced digital sampling technique and high-speed scanning test fixture that make the transformer testing. Our products are easily available in the market, according to the demand of the customer. We can design Auto Transformers to meet our clients exact requirements. We are continuously working as an economical alternative to three phase regular function distribution transformers to regulate the supply voltage and match up with specific load requirements, load isolation from the supply line is not required .
