FS56-350

Description:

The FS56-350 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 56.0V with a center-tap under a 0.35A load with the

secondaries wired in series, or 28.0V under a 0.7A load with the secondaries

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

electrostatic shielding.
