F28-085-C2 Datasheet, PDF (1/1 Pages) TRIAD MAGNETICS – CLASS 2/3 TRANSFORMER1

CLASS 2/3 TRANSFORMER
F28-085-C2
Description:
The F28-085-C2 is a single primary and dual secondary, split bobbin design which
operates with an input of 115V. The secondaries are 14V @ 0.085A 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: 2.5VA
2. Primary: 115V
3. Secondaries: 14.0V @ 0.085A 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. Inherently Limited. No fusing required.
Construction:
Three flange bobbin construction with primaries and secondaries wound side by
side for low capacitive coupling. UL Class F Insulation System (155°C).
