Downloads for PC Mount Split Pack™ Class 2/3 Power Transformers (FS48-250-C2)

CLASS 3 TRANSFORMER
FS48-250-C2
Description:
The FS48-250-C2 is a series/parallel primary and dual secondary, split bobbin
design which operates with either a parallel input of 115V or a series input of 230V.
The secondaries are 24V @ 0.25A each. They can be used independently (up to
300V difference between them) or in series for double the voltage or in parallel for
double the current. The split bobbin design eliminates the need for costly
electrostatic shielding.
