FS24-500-C2

Description:

The FS24-500-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.

secondaries are 12V @ 0.5A 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)

2. Primary: Series: 230V; Parallel: 115V

3. Secondaries: 12.0V @ 0.5A each

4. Voltage Regulation: 25% TYP @ full load to no load

5. Operating Temperature: -40C to 80C

6. Storage Temperature: -55C to 150C

7. Hipot tested 100% at 4200 VRMS pri to sec

8. Hipot tested 100% at 2160 VRMS sec to sec

Construction:

Three flange bobbin construction with primaries and secondaries wound side by

side for low capacitive coupling.

UL Class F Insulation System (155°C).
