3-8. CONTINUOUS OUTPUT RATE, 28.5 VDC CONSTANT OUTPUT
100 amp hours (with AC power connected)
NOTE
If current demand exceeds 100 amps, converter output voltage will
drop below 28.5 VDC and two or more LED status indicator bars will
illuminate. If all LED status indicator bars illuminate, both the
converter and power cells are supplying 24 VDC power output (see
paragraph 3-4 and 4-7.4.).
3-9. ENGINE STARTING POWER
Operators should always ensure the unit is charged above 80% prior to
ground support engine starting. However, circumstances may exist
during use where unit recharge is not readily available and immediate
external engine starting power is required. The following provides
minimum states of charge necessary to provide ample power for an ef-
ficient engine start under specific current load demands.
ENGINE START CURRENT LOAD DEMAND MINIMUM CHARGE
Under 650 peak starting amps 40% charged
650-850 peak starting amps 50% charged
850-1000 peak starting amps 60% charged
1000-1200 peak starting amps 70% charged
1200-1500 peak starting amps 80% charged
3-10. TEMPERATURE
Temperatures refer to the unit’s cold/heat soaked temperature. A
unit’s cold/heat soaked temperature shall be established by the ambi-
ent temperature that a unit is exposed to for one (1) hour or more.
If unit’s cold/heat soaked temperature exceeds operating temperature
range, unit shall be stabilized prior to operation as follows: COLD
SOAKED, warmed for a minimum of 3 hours above +10Co (+41oF) or 2
hours above +20Co (+68oF); WARMED SOAKED, cooled for 1 hour below
+38Co (+100oF).
Operating range:
without AC power -40Co (-40oF) TO +60Co (+140oF)
with AC Power -30Co (-22oF) TO +50Co (+124oF)
Storage range:
-60Co (-76oF) TO +60Co (+140oF)
