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.
