Dantrafo DT I8555-1 Power Transformer


Industrial power transformers are used across a wide range of industries to step-up or step-down the current and voltage levels in a circuit while maintaining the overall power.

Industrial equipment does not always run on the type of circuit that a building offers. That’s why industrial applications rely on transformers to get the right voltage to electrical equipment. Transformers are employed for widely varying purposes. E.g.: To reduce the voltage of conventional power circuits to operate low-voltage devices, such as doorbells and toy electric trains, and to raise the voltage from electric generators so that electric power can be transmitted over long distances.
