Drive transformers

Use of variable frequency drives to optimize the electrical motor speed is an economical solution for saving energy. Often a transformer is needed to adjust the network voltage or motor voltage to the drive voltage. Also the use of 3 or 5 winding transformers is a good way to decrease the harmonic distortion to the network.

Trafotek can provide customers reliable solutions that ensure that our customers will have best possible electricity to all electrical components. Our long-term cooperation with major drive manufactures gives us the best possible technical vantage point.
