P OWE R T RAN S FO R M E R P C M O U N T : SPLIT PACK FS56-350 Description: The FS56-350 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 56.0V with a center-tap under a 0.35A load with the secondaries wired in series, or 28.0V under a 0.7A load with the secondaries wired in parallel. The split bobbin design eliminates the need for costly electrostatic shielding. Electrical Specifications (@25C) 1. Maximum Power: 20.0VA 2. Primary: Series: 230V; Parallel: 115V 3. Secondary: Series: 56.0V CT@ 0.35A; Parallel: 28.0V @ 0.7A 4. Voltage Regulation: 25% TYP @ full load to no load 5. Temperature Rise: 25C TYP 6. Hipot tested 100% at 2500 VRMS W Construction: Three flange bobbin construction with primaries and secondaries wound side by side for low capacitive coupling.
