CLASS 3 TRANSFORMER F56-350-C2 Description: The F56-350-C2 is a single primary and dual secondary, split bobbin design which operates with an input of 115V. The secondaries are 28V @ 0.35A 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: 20.0VA 2. Primary: 115V 3. Secondaries: 28.0V @ 0.35A 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 W Construction: Three flange bobbin construction with primaries and secondaries wound side by side for low capacitive coupling.
