CLASS 2/3 TRANSFORMER

FS28-420-C2

Description:

The FS28-420-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 14V @ 0.42A 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: Series: 230V; Parallel: 115V

3. Secondaries: 14.0V @ 0.42A 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): For 115V - Cooper/Bussman, Type MDL,

rated 500mA, 250V. For 230V – Littlefuse, Type 313, rated 250mA, 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).
