The Pulse Transformers IT series with double secondary winding offers galvanic separation between drive and power circuits, providing voltage resistance up to 4 kV and ignition currents up to 1 A. These transformers are designed for various switching applications, power supplies, and data transmission, featuring vacuum potting for very low partial discharge effects and PCB through-hole mounting. Custom-specific versions are available upon request.
