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.
