FEATURES

DESCRIPTION

The 772 series of pulse transformers are intended

for medium power applications in switch mode

power supplies and thyristor/triac ﬁring (e.g.

motor control applications). The standard turns

ratios may be modiﬁed on any transformer with

three windings by connecting any two windings

in series.
