Limitations : 200 amps maximum DC load
NOTE- When using more than 58 continuous amps, the batteries will make up the difference until they become depleted. On most aircraft, a low voltage relay will drop the GPU offline when the voltage drops below a preset level. Once the GPU is dropped off, it’s 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:
38"x21"x20" Handle Height 48".

Features- The GPU is rated at 3200 peak starting amps and a continuous 58 Amp DC output when connected to a 110 Volt or 220 Volt AC source. This airplane starting unit has a large battery capacity (78 Ah) that will allow extended usage time when no AC power source is available.

The 3324 weighs 215 lbs. and is pulled by hand or tug. Locking the handle in an upright position sets the GPU brake. Always recharge the GPU until green charger light appears. Once charged, it is not necessary to leave the unit turned on. If a heater is installed, leave unit plugged in.
Avoid discharging the batteries completely as damage can result.

NOTE-- PLEASE USE #12 or Larger AC EXTENSION CORD

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, it’s 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:
38"x21"x20" 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. 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

These ground power units are designed to perform starting, powering up aircraft systems and maintenance functions. When connected to AC power, the depleted batteries can be charged in a matter of hours with the built in power supply/battery charger.

The 3328 contains a full 28 volt battery pack for starting and a large power supply to provide a continuous current at 28.5 Volts DC for maintenance . This mobile GPU with 175 amp power supply will satisfy the ground power requirements of most business jets including on board air conditioning.

We also custom manufacture Start Pac® units in various combinations of batteries and power supplies to meet the customers' exact requirements.

BATTERY DISCONNECT: When operating the continuous power supply at 105 or 175 amps and below, activate the battery disconnect. Since the 28.5 batteries actually read 30.5 Volts at rest, leaving the battery disconnect connected will deplete the batteries nearly 50% before their voltage reaches 28.5 Volts. Thus in this situation only one half of the battery capacity will be available for engine starting. By keeping the batteries separated from the continuous power supply, you will have full battery capacity for engine starts. If you need more than 105 or 175 continuous amps, then use the battery disconnect and the batteries will make up any amperage needed.

Features:

• This GPU is rated at 2800 peak starting amps and is a full 28.5 Volt unit. Due to the extra starting power provided by the 28.5 Volt batteries, turbine engines will experience faster, cooler starts and extended turbine life. This model is primarily designed for superior starts on large turbine engines and the Garrett TPE 331.
  
  
• This unit is more economical than the 3328 as it does not incorporate the high output DC power supply. Also this unit can be configured 110 Volt or 220 Volt AC input. This unit weighs 185 lbs/83.92 kilos.

Always recharge the GPU until the green light appears. Once charged, it is not necessary to leave unit plugged in. If heater is installed, turn unit off but leave plugged in.

Avoid discharging the batteries completely as damage to the cells can result.
Always recharge batteries soon after use.
