IT pulse transformers are designed to offer
you galvanic isolation for transformer coupled
gate drives. The IT series provides negligible
delays and the possibility of voltage scaling.
They are available with single or double
secondary winding for multiple gate drives.
Choosing the IT product line brings you the
rapid availability of a standard gate drive
transformer. A wide selection on turns ratio,
ignition current and voltages are designed to
offer you the desired standard product.
