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.

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 +10C
