FS48-125
Description:
The FS48-125 is a dual primary and dual secondary, split bobbin design which
operates with either a parallel input of 115V or a series input of 230V. 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.
