Downloads for PC Mount Split Pack™ Class 2/3 Power Transformers (F28-85-C2)

CLASS 2 TRANSFORMER
F28-85-C2
Description:
The F28-085-C2 is a single primary and dual secondary, split bobbin design which
operates with an input of 115V. The output voltage will be either 28.0V with a
center-tap under a 0.085A load with the secondaries wired in series, or 14.0V
under a 0.17A load with the secondaries wired in parallel. The split bobbin design
eliminates the need for costly electrostatic shielding.
