CLASS 3 TRANSFORMER
W
F48-400-C2
Description:
The F48-400-C2 is a single primary and dual secondary, split bobbin design which
operates with an input of 115V. The secondaries are 24V @ 0.4A 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.
