The Model 3324 GPU is a combination power supply and battery pack.
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, itís 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
