Federal Pacific dive isolation transformers are designed to meet the requirements of SCR controlled variable speed motor drives. They are specifically constructed to withstand the mechanical forces associated with SCR drive duty cycles and to isolate the line from most SCR generated voltage spikes and transient feedback. Similarly, the two-winding construction also aids in reducing some types of line transients that can cause misfiring of the SCR's.
The units are UL Listed and incorporate all the features of the FH transformer line. The transformers can also be supplied as core and coil units with UL component recognition.
Delta-wye designs are available for commonly used primary and secondary voltages. All units include primary taps consisting of one 5% FCAN and one 5% FCBN.
