This GPU is rated at 2800 peak starting amps and is a full 28 volt battery pack (28.5 volt, to be exact). 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 airplane starting unit is more economical than the 3328 as it does not incorporate the high output DC power supply. Also, this unit can be configured for 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.
There are approximately thirty 110 volt and thirty 220 volt NEMA plugs in use. Also, customers have various receptacle at their hangars and MRO facilities and may require specific AC cord length to meet their requirements. Due to these facts, we do not automatically provide AC power cords. 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 for a small fee.
NOTE- PLEASE USE #12 or Larger AC EXTENSION CORD
