Operating Procedures
Figure 3.10.1 Connecting TI1000 GPU-24 UAV to
ac power supply
Figure 3.10.2 AC North American Line Cord
3.10 – Regulated AC Power
Plugging in with AC Power
When the TI1000 GPU-24 UAV is plugged into ac power, the output is 28.5 volts. This voltage allows the
system to recondition and recharge the vehicle’s battery(s). It is also an optimum voltage for powering
avionics and lighting on most aircraft. The GPU’s ac to dc converter produces continuous amps of dc power
depending on the size of the system.
Connect AC Power Cord To Unit
Ensure 120 or 240 Vac power cord is properly connected to an approved ac power supply. After approximately
5-8 seconds, unit’s LED status indicator will illuminate indicating power cell state of charge. Cooling fan will
operate. Ensure LED status indicator and cooling fan is operational prior to continuing.
3.11 – Charging Unit
Once you have the voltage selector switch set to match the power characteristics of your line cord, you can
plug the unit into a wall socket to charge the batteries. Until the unit is fully charged, the LED status will read
half or no charge. Plug the TI1000 GPU-24 UAV into ac power to keep the cells charged whenever it is not in
use, even if it is at Full Charge. The unit will not overcharge or overheat.
If you received this manual with a new GPU.
When the Unit is fully charged the LED indicator should show a single steady green bar. The fan will also
come on at reduced speed. This is normal operation indicating the unit is in standby mode and is ready for
use.
If you own an older GPU and this is a replacement manual.
Under a full charge the LED indicator should show a single steady green bar or the entire LED will be blinking.
The fan will also exhibit ratcheting but will not come on. This is normal operation indicating the unit is in
standby mode and is ready for use.
If the GPU’s cells need to be replaced.
After 60 minutes of ac power input, the unit should be fully charged. If the “Push to Test” button is pressed
and the unit still indicates it is not fully charged then the cells should be replaced.
NOTE
!
Check Input Voltage Selector Switch for proper setting.
