Product Description
Pulse Transformers IT Series with Double Secondary Winding
The Pulse Transformers IT series with double secondary winding provide galvanic separation between drive and power circuits, offering voltage resistance up to 4 kV and ignition currents up to 1 A. These transformers feature a turns ratio up to 3:1:1 and are designed for applications requiring high isolation and precise pulse shaping. Key advantages include excellent galvanic isolation, high voltage withstand capability, and very low partial discharge effects due to vacuum potting. They are suitable for PCB through-hole mounting and custom versions are available upon request.
