F48-125
Description:
The F48-125 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 0.125A load with the secondaries wired in series, or 24.0V
under a 0.25A load with the secondaries wired in parallel. The split bobbin
design eliminates the need for costly electrostatic shielding.
