The Schaffner IT series pulse transformers provide galvanic isolation between drive and power circuits, offering voltage resistance up to 8 kV and ignition currents up to 3 A. Designed for transformer-coupled gate drives, they ensure negligible delays and allow for voltage scaling. Available with single or double secondary windings, these transformers offer rapid availability and a wide selection of turns ratios, ignition currents, and voltages to meet various application needs.
