UNIT DESCRIPTION AND OPERATION
SECTION I. UNIT
2-1. GENERAL
The TI2000GPU-24 (Turbo Start 2000) (Figure 2-1 and 2-2) is a compact, portable
and highly versatile 24/28.5 VDC electrical ground power unit. The unit incor-
porates a 120-240 VAC to 28.5 VDC converter, a 24 volt unique (dry) power cell
and an internal intelligent 120 to 240 volt AC charger to recharge the power
cells. These built-in features give the Turbo Start 2000 self-sufficiency and
mobility for short-term operations without AC electrical power or long term
operations with AC electrical power. Short term operations rely solely on
power cell output and the fast recharge rates that the unit’s internal charger
provides from any standard 120 or 240 VAC electrical outlet. Longer term op-
erations incorporate the continuous 20 amp output of the 120-240 VAC to 28.5
VDC converter, or a combination of converter and power cell output to provide
24 VDC output. The following are the unit’s four (4) main operational support
capabilities:
a. 24 VDC 3000 amp peak power output for engine starting or constant (one
hour) rated power output (without a 120-240 VAC power source) for short term
trouble shooting and flexible flight line support ground power.
b. 24 VDC constant (one hour) rated power output or variable high load de-
mand output (less than one hour) with a 120-240 VAC power source for extended
maintenance (hangar) and routine flight line maintenance, ground support
power.
c. 28.5 VDC continuous rated (AC to DC converter) power output with a 120-
240 VAC power source for hangar and routine flight line maintenance support,
and avionics bench testing.
d. Rapid recharge of the unit’s power cells from any 120-240 VAC common
power source. This feature eliminates the need for special recharge equip-
ment and dedicated maintenance support man-hours.
WARNING
Check fuse holder window to ensure the fuse setting reads either 120 or
240 prior to connecting recharge cord to AC power source. Fuse setting (120/
240) must match AC power source (hangar wall, flight line AC power) prior to
connecting TURBO START for recharging.

SECTION II. OPERATIONAL RESTRICTIONS AND SAFETY LIMITS
3-3. POWER CELL RECHARGE LIMITS
Any time the unit’s power cells are fully discharged the unit shall
be recharged within 24 hours to prevent performance degradation and
ensure maximum life.
CAUTION
Unit’s power cells may be damaged if recharged by NiCad or Lead Acid-
type battery chargers. Power cells should only be charged by either
the TURBO START internal charger and the AC power cord furnished with
the equipment, or when connected aircraft external DC power recep-
tacle.

3-1
3-4. 120-240 VAC CHARGER AND AC TO DC CONVERTER LIMITS
The unit is designed with a single point AC receptacle for external
power to operate both the internal charger and converter. The units
AC voltage range can be factory set from 105 to 250 VAC at 50 to 60
Hz depending upon customer requirements. The AC power cord provided
with the unit is the mechanism that ensures the specified AC power
source is properly supplied to the unit (see paragraph 3-5).Use no
others
INTERNAL CHARGER: NO LIMIT AC power cord can remain connected
when power cells are fully charged. When the power cells are fully
charged the unit’s intelligent charger will go to a stand-by mode,
monitor the power cells state of charge, and only charge the power
cells to ensure they stay at maximum capacity.
INTERNAL AC TO DC CONVERTER: LIMITED (see paragraph 3-6, 3-8 and
3-10). AC power cord does not have to be disconnected when con-
verter power output is no longer required. Once DC power demand
is terminated the unit’s intelligent charger will remain on line to
ensure power cells are charged to maximum capacity.
CAUTION
Unit will be damaged if unapproved AC power is applied.
3-5 AC POWER CORD LIMITS
The AC power cord governs which AC power source the unit is set to
operate from. The Turbo Start 2000 is supplied with a single cus-
tomer specified AC power cord. Some customers may specify a univer-
sal AC option (for worldwide mobility), which comes with two (2)
power cords, one for 120 VAC 60 Hz and the other for 240 VAC 50 Hz
(SEE APPENDIX A). Each power cord is marked accordingly. Below are
the following three (3) types of AC power cords available and their
