CLASS 2/3 TRANSFORMER FS28-420-C2 Description: The FS28-420-C2 is a series/parallel primary and dual secondary, split bobbin design which operates with either a parallel input of 115V or a series input of 230V. The secondaries are 14V 0.42A 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: 12.0VA 2. Primary: Series: 230V Parallel: 115V 3.
