F48-250
Description:
The F48-250 is a single primary and dual secondary, split bobbin design which
operates with an input of 115V. The output voltage will be either 48.0V with a
center-tap under a 0.25A load with the secondaries wired in series, or 24.0V
under a 0.5A load with the secondaries wired in parallel. The split bobbin design
eliminates the need for costly electrostatic shielding.
Electrical Specifications (@25C)
1. Maximum Power: 12.0VA
2. Primary:
3. Secondary: Series: 48.0V CT@ 0.25A
