FS10-250

Description:

The FS10-250 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 10.0V with a center-tap under a 0.25A load with the

secondaries wired in series, or 5.0V under a 0.5A load with the secondaries wired

in parallel. The split bobbin design eliminates the need for costly electrostatic

shielding.
