## **CLASS 3 TRANSFORMER** ## **FS48-125-C2** ## **Description:** The FS48-125-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 24V @ 0.125A 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: 6.0VA 2. Primary: Series: 230V; Parallel: 115V 3. Secondaries: 24.0V @ 0.125A each **==> picture [537 x 443] intentionally omitted <==** **----- Start of picture text -----**<br> W<br>4. Voltage Regulation: 25% TYP @ full load to no load<br>5.

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.
