The Pulse Transformers IT series with double secondary winding provide galvanic separation between drive and power circuits. They offer voltage resistance up to 4 kV and ignition currents up to 1 A, with turns ratios up to 3:1:1. These transformers are designed for applications requiring high potential difference voltage scaling and feature very low partial discharge effects due to vacuum potting. They are suitable for PCB through-hole mounting and custom-specific versions are available on request.

Note: Lp primary inductance measured at 1 kHz (secondary coil open). Lstr stray inductance measured at the secondary side, short circuit at the primary side. If there are several secondary coils, only one at a time is connected (measuring frequency 10 kHz). The ignition current is a set peak value where the voltage drop over the coil resistance is still insignificant (mostly below 1 V).
