These GPU’S are designed for ground use to perform mainly starting functions. When connected to AC power, the depleted batteries can be charged in four hours with the built in power supply/battery charger.

This unit is designed to provide superior starting for large turbine engines including the TPE 331.

The Model 3328 GPU is a combination power supply and battery pack.

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.

*** There are approximately 30 110 volt and 30 220 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 CABLE
