Tesla TI4676 - Manual (Page 14)

3-8. CONTINUOUS OUTPUT RATE, 28.5 VDC CONSTANT OUTPUT
35 Amps at 1 hour (with AC power connected)
NOTE
If current demand exceeds 12 amps, converter output voltage will drop
below 28.5 VDC and two or more LED status indicator bars will illumi-
nate. 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)
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 dur-
ing use where unit recharge is not readily available and immediate ex-
ternal engine starting power is required. The following provides mini-
mum states of charge necessary to provide ample power for an efficient
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. The
ambient temperature that a unit is exposed to for one (1) hour or more
shall establish a unit’s cold/heat soaked temperature. 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 +10C
o
(+41
o
F) or 2 hours above +20C
o
(+68
o
F);
WARMED SOAKED, cooled for 1 hour below +38C
o
(+100
o
F).
Operating range:
without AC power -40C
o
(-40
o
F) TO +60C
o
(+140
o
F)
with AC Power -30C
o
(-22
o
F) TO +50C
o
(+124
o
F)
Storage range:
60C
o
(-76
o
F) TO +60C
