Model 3324

PATENTED

Clean, dependable and long lasting, START PAC’s Model 3324 is an advanced ground power unit (GPU); it’s designed for use in performing starting and maintenance functions on the ground, not only at home, but also in more remote ramp locations when you might need an extended time period for maintenance checks.  With its large battery capacity (78AH), it has a 58-amp power supply when connected to 110 Volt or 220 Volt AC.

The Model 3324 GPU is a combination power supply and battery pack.  With its built-in, portable power supply/battery charger, it is capable of recharging its depleted batteries in a matter of hours when connected to an AC supply.

Batteries

  • Sealed cells, non- hazardous
  • Valve regulated, high amperage output lead acid

The following dimensions apply to each of the 3300s:
L 38″ x W 21″ x H 20″/L 96.52cm x W 53.34cm x H 50.8cm; Handle Height 48″/121.92cm

We also custom manufacture units in various combinations of batteries and power supplies in order to meet our customers’ exact requirements, (e.g. a 24 volt power supply).

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.  Unfortunately, the GPU’s voltage will then rise back up, causing the aircraft to make use of it once more.  This, in turn, will cause it to re-drop below its preset level again, creating a vicious circle.  It is this oscillation that can cause damage to aircraft components.

Features:

This portable 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.

The unit has a large battery capacity (78 Ah) that will allow extended usage time, even when no AC power source is available.

The 3324 weighs 215 lbs. and can be pulled by hand or tug; locking the handle in an upright position sets the GPU brake.

Always recharge the GPU until the green charger light appears.  Once charged, it is not necessary to leave the unit turned on.  If a heater is installed, leave the unit plugged in.

Avoid discharging the batteries completely as damage could result.

We also carry portable starting units powered by lithium batteries, other GPUs and power supplies.  If you would like more information about the products featured on this page, please submit a brochure request and we will be happy to mail you a hard copy.

NOTE  PLEASE USE #12 or Larger AC EXTENSION CORD

There are approximately thirty 110 volt and thirty 220 volt NEMA plugs in use with this unit.  Additionally, customers will have differing receptacles at their hangars and MRO facilities and may require specific AC cord lengths in order to meet their requirements.  Consequently, we do not automatically provide AC power cords.  However, for a small fee, if you provide the NEMA plug number and specify the AC power cord length you require, we will build a cord to be shipped with your unit.

All START PAC™ products come with a 1-year warranty on workmanship and materials.*

Please handle this unit in a responsible manner.  START PAC™ is not responsible for damages caused by misuse or neglect.
