P OWE R T RAN S FO R M E R Chassis Mount: Universal F-91X Electrical Specifications (@25C) 1. Primary: 115V1, 60 Hz 2. Secondary: 0-10V, 20VCT, 40VCT @ 0.3ADC2 3. Temperature Rise: 35C TYP (45C MAX allowed) 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.
