## **CLASS 2 TRANSFORMER** 

## **F28-85-C2** 

## **Description:** 

The F28-085-C2 is a single primary and dual secondary, split bobbin design which operates with an input of 115V. The output voltage will be either 28.0V with a center-tap under a 0.085A load with the secondaries wired in series, or 14.0V under a 0.17A 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: 115V 

3. Secondary: Series: 28.0V CT@ 0.085A Parallel: 14.0V @ 0.17A 

4. Voltage Regulation: 25% TYP @ full load to no load 

5. Temperature Rise: 25C TYP 

6. Hipot tested 100% at 2500 VRMS 

7. Inherently Limited. No fusing required. 

## **Construction:** 

Three flange bobbin construction with primaries and secondaries wound side by side for low capacitive coupling. UL Class F Insulation System (155°C).
