## **FS20-120** 

## **Description:** 

The FS20-120 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 20.0V with a center-tap under a 0.12A load with the secondaries wired in series, or 10.0V under a 0.24A load with the secondaries wired in parallel. The split bobbin design eliminates the need for costly electrostatic shielding. 

## **Electrical Specifications (@25C)**
