The 3328 is a full 28.5 Volt unit that will give faster, cooler starts on all turbine engines. The 50 Amp power supply is large enough to power various systems such as inverters, avionics and GPS. Always recharge after use until the green charger light appears. Once charged, leave the unit plugged in. Avoid fully discharging the batteries as damage to the cells may result.
The Model 3328 GPU is a combination power supply and battery pack.

When operating the continuous power supply unplug the battery disconnect. Although this unit is equipped with 28.5 Volt batteries, it will actually read 30.5 Volts at rest. Leaving the disconnect connected will deplete the batteries nearly 50% before their voltage reaches 28.5 Volts. Thus, 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 50 continuous amps, using the battery disconnect will enable the batteries to make up for any amperage needed.
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
