Product Description

The M1428-DV Mini-GPU is a specialized switching-mode power supply designed to provide pilots and aviation maintenance professionals with a portable, affordable source of stable, high-current, noise-free DC power that replicates the in-flight electrical environment. It contains discrete outputs for either 14 or 28-volts DC, selectable by a front panel switch. It only provides one output voltage at a time, switch-selected and indicated by the front panel voltmeter display. The GPU’s intended purpose is to energize an aircraft’s main electrical bus without using the ship’s battery or engine. It will safely provide continuous power for the most delicate electronics and airframe systems up to its full rated output.

The Model M1428-DV provides 14-volt DC power for:

Avionics demonstration and testing
Database and firmware updates
Flight planning and cockpit procedures training
Troubleshooting & maintenance
Powered pre-flight inspections and battery top-off

The Model M1428-DV comes with two 6-feet airframe output cables – one with a yellow SB50 for 14V output, and one with red for 28 volts – to protect from damage due to accidental voltage mismatch. Both output cables have AN2551 3-pin oval plug that connects to the aircraft. For E/A-B connections, the 802-864 yellow to yellow SB50 may be purchased separately.
