P O W E R T R A N S F O R M E R P C M O U N T : SPLIT PACK F56-350 Description: The F56-350 is a single primary and dual secondary, split bobbin design which operates with an input of 115V. 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: 115V 3. Secondary: Series: 56.0V CT 0.35A Parallel: 28.0V 0.7A W 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.
