Laptop Power Supply Module (AP9125)

Product Overview

The AP9125 Laptop Power Supply Module is a 28VDC powered voltage
converter unit developed to provide a low voltage high power regulated power supply for ruggedised laptop PC's in an airborne environment.

Typical applications include moving map, search and rescue the Metropolitan Police (ANPR) system.

The AP9125 is available in a number of configuraitons including 12V, 15V, 19V and 24V output with the option of 50W or 100W power rating.

The AP9125 can also accomodate custom output voltages in the range 12V to 24V in 0.1V increments,
this must however be specified at the time of order placement and is not field programmable.
