FS28-200
Description:
The FS28-200 is a dual primary and dual secondary, split bobbin design which
operates with either a parallel input of 115V or a series input of 230V. The output
voltage will be either 28.0V with a center-tap under a 0.2A load with the
secondaries wired in series, or 14.0V under a 0.4A load with the secondaries
wired in parallel. The split bobbin design eliminates the need for costly
electrostatic shielding.
Electrical Specifications (@25C)
1. Maximum Power: 6.0VA
2. Primary:
Series: 230V; Parallel: 115V
3. Secondary: Series: 28.0V CT@ 0.2A; Parallel: 14.0V @ 0.4A
4. Voltage Regulation: 25% TYP @ full load to no load
5. Temperature Rise: 25C TYP
6. Hipot tested 100% at 2500 VRMS
Construction:
Three flange bobbin construction with primaries and secondaries wound side by
side for low capacitive coupling.
