7hills Variac

Our noteworthy entity is engaged in manufacturing and supplying a premium quality range of Variable Voltage Auto Transformers. We prepare a wide range of Variable Voltage Auto Transformer, which is suitable for both indoor & outdoor applications. It has a wide current which ranges from 2 A to 500 A both in air & oil cooled. We have supplied thousands of these variable voltage auto transformers to various industries. The quality of our Variable Voltage Auto Transformer is well patronized with repeat orders from our customers. The plant is well equipped with the modern machinery & test equipment to conduct tests as per IS: 5142. Our professionals have incorporated in them various features for providing a long lasting and reliable product, to withstand the high temperatures and faster dissipation of heat generated.

Design :  Pion research has developed design features and proprietary process providing long lasting, more reliable products. Particularly to withstand high temperatures and faster dissipation of heat generated.

Voltage Ratings : Basic single scroll variable voltage auto transformer (variac) are rated either at 240v ac or 120v ac, for 1 ph application one coil is used, for 2ph applications two coils are used and for 3 ph application three coils are used. For some applications connected in series to withstand high voltages.

Current Ratings :  Air cooled from 2 amps to 100 amps in 1 ph, 2 ph, 3 ph oil cooled from 2 Amps to 500 Amps in 1 ph, 2 ph, 3 ph no. of coils are paralleled to increase current carrying capacity.
