Product Description
Pulse Transformers IT series with single secondary winding
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, featuring negligible delays and voltage scaling capabilities. Available with single or double secondary windings, these transformers ensure rapid availability of standard gate drive solutions with a wide selection of turns ratios, ignition currents, and voltages.
