F56-350-C2 Triad

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 W 4.
