The 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. They are designed for transformer-coupled gate drives, ensuring negligible delays and the possibility of voltage scaling. Available with single or double secondary windings, these transformers offer rapid availability as standard gate drive transformers with a wide selection of turns ratios, ignition currents, and voltages.
