## **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 ## **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)** 1. Maximum Power: 2.5VA 2. Primary: Series: 230V; Parallel: 115V 3. Secondary: Series: 20.0V CT@ 0.12A; Parallel: 10.0V @ 0.24A **==> picture [532 x 444] intentionally omitted <==** **----- Start of picture text -----**<br> W<br>4.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
