Product Description
Pulse Transformers IT series with double secondary winding
The Pulse Transformers IT series with double secondary winding offer galvanic separation between drive and power circuits, providing voltage resistance up to 4 kV and ignition currents up to 1 A. They are suitable for applications requiring high potential difference voltage scaling due to their vacuum potting and very low partial discharge effects. These transformers are designed for PCB through-hole mounting and custom-specific versions are available upon request.
