F56-220-C2-B Datasheet, PDF (1/1 Pages) TRIAD MAGNETICS – CLASS 3 TRANSFORMER

CLASS 3 TRANSFORMER
F56-220-C2
Description:
The F56-220-C2 is a single primary and dual secondary, split bobbin design which
operates with an input of 115V. The secondaries 28V @ 0.22A 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.
Electrical Specifications (@25C)
1. Maximum Power: 12.0VA
2. Primary: 115V
3. Secondaries: 28.0V @ 0.22A each
4. Voltage Regulation: 25% TYP @ full load to no load
5. Temperature Rise: 25C TYP
6. Hipot tested 100% at 4200 VRMS pri to sec
7. Hipot tested 100% at 2160 VRMS sec to sec
8. Recommended fuse (fuse on primary): Cooper/Bussman, Type MDL, rated
500mA, 250V
Construction:
Three flange bobbin construction with primaries and secondaries wound side by side
for low capacitive coupling. UL Class F Insulation System (155°C).
