**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 

## **F28-200** 

## **Description:** 

The F28-200 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 0.2A load with the secondaries wired in series, or 14.0V under a 0.4A load with the secondaries wired in parallel. The split bobbin design eliminates the need for costly electrostatic shielding. 

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

1. Maximum Power: 6.0VA 

2. Primary: 115V 

3. Secondary: Series: 28.0V CT@ 0.2A Parallel: 14.0V @ 0.4A
