3324-1/175

These GPUS are designed for ground use to perform starting and maintenance functions. This unit can be used in remote ramp locations using battery power alone and give extended time for maintenance checkout. When connected to AC power, the depleted batteries can be charged in less than two hours with the built in power supply/battery charger.START PAC MODEL 3324-1, 24 VDC
INSTRUCTIONS AND INFORMATION
The Model 3324-1 GPU is a combination power supply and battery pack.
Batteries: 52 Amp Hours at 10 hour rate
24 Volt DC- 25.5 Volts at rest
Sealed cells non-hazardous
Valve regulated high amperage output lead acid
2800 Peak Amps
Power 105 or 175 amps DC continuous output at
supply/ 28.5 Volts. Battery recharge time from fully
charger: discharged 1 hour AC Input 220 Volts only
Limitations: 250 amps maximum DC load. NOTE- When using
more than 105 or 175 continuous amps, the batteries will make up the difference until they become depleted. On most aircraft, a low voltage relay will drop below a preset level. Once the GPU is dropped off, its voltage will rise and will be accepted again by the aircraft, then will immediately drop off again. This oscillation can cause damage to aircraft components.
The following dimensions apply to each of the 3300s:
Length 36 Width 22 Height 20 Handle Height 48.
Features- The GPU is rated at 2800 peak starting amps and a continuous 105 or 175 amps DC output when connected to a 220 Volt AC source. Units can be serviced in the field if
necessary. This unit has a large battery capacity (52Ah) that will allow extended usage time when no AC power source is available.
The 3324-1 weighs 200 Lbs. and is pulled by hand or tug. Locking the handle in an upright position sets the GPU brake.
Always recharge the GPU until charger green light appears. Once charged, it is not necessary to leave the unit turned on. If a heater is installed, leave unit plugged in.
NOTE-PLEASE USE #12 or LARGER AC EXTENSION CABLE
