Description:
The F-91X is a chassis mount power transformer that was designed with multiple primaries and
secondaries to give the user maximum flexibility. The F-91X is intended for use with full wave center tap
or bridge rectifiers, but may be used with voltage doubler circuits at one half of the rated current.
Construction:
Wound on a single channel nylon bobbin. Materials are UL recognized, Class B (130º C) rated.
Safety:
These products are 100% hipot tested with an insulation of 1500V between primary and secondary
windings as well as between the primary / secondary windings and the core.
