**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 

## **F20-055** 

## **Description:** 

The F20-055 is a single primary and dual secondary, split bobbin design which operates with an input of 115V. The output voltage will be either 20.0V with a center-tap under a 0.055A load with the secondaries wired in series, or 10.0V under a 0.11A load with the secondaries wired in parallel. The split bobbin design eliminates the need for costly electrostatic shielding. 

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

1. Maximum Power: 1.1VA 

2. Primary: 115V 

3. Secondary: Series: 20.0V CT@ 0.055A Parallel: 10.0V @ 0.11A 

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

5. Temperature Rise: 25C TYP 

6. Hipot tested 100% at 2500 VRMS 

## **Construction:** 

Three flange bobbin construction with primaries and secondaries wound side by side for low capacitive coupling.
