AC, DC , ACDC High Current Sources

We bring forth our vast industrial experience and expertise in this business, involved in manufacturing and exporting of AC, DC, ACDC High Current Sources. Testing current instrument transformers requires a high current power supply ready to regulate currents in a wide from A to kA. The high current source is specially designed to meet the stringent requirement. Based on the state-of-the-art frequency converter technology it offers flexibility and ease of use. It is specially designed for current instrument transformer (CT) testing. A current source is the dual of a voltage source.
