Section 2 – Product Overview
2.1 – Introduction
Thank you and congratulations on the purchase of your new TI1550 12-24-UAV GPU Ground Power Unit.
This manual contains the complete operating instructions and procedures for the TI2560-12-24 Ground
Power Unit. The TI1550 12-24-UAV GPU serves as a stand-alone source of dc electrical power for aircraft
systems and ground support maintenance operations. Using a single 120 Vac power source, the TI1550
12-24-UAV GPU provides regulated outputs of 14.25 Vdc at 20 amps continuous and 28.5 Vdc at 25 amps
continuous. For vehicle and aircraft starting, the 12 Vdc and 24 Vdc outputs can deliver up to 1500 peak
amps.
The unit’s high-capacity power cells and circuitry are encased in a rugged enclosure. This internal circuitry
incorporates an intelligent recharging system that allows the TI1550 12-24-UAV GPU to rapidly recharge
from any standard 110-130 Vac outlet receptacle. The unit also comes equipped with independent dual
outputs and built-in Charge Status Meters (via the “Push to Test” button) that also serve as recharge state
indicators for both dc outputs.
