The environmentally responsible, low VOC powder coating protects the case from wear, tear and poor weather conditions. Additionally, an all-weather cover accessory is also available as an option for this unit in order to protect it further from inclement weather to gain the maximum performance and product life.

Additionally, START PAC® custom manufacture units in various combinations of batteries and power supplies to meet our customer’s exact requirements.

Features:

• This mobile 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 (84 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.

Designed for Engine Starting and Maintenance Power

The Model 3324™ / 58 AMP is a dual-purpose aircraft ground power unit built to handle both engine starting and continuous maintenance power applications. This gives operators a practical way to support aircraft before, during, and after service work using one mobile system.

It can be used to help power aircraft systems during maintenance, training, and operational checks while also delivering strong starting support for turbine and piston aircraft applications.

Key Benefits of the Model 3324™ / 58 AMP

The START PAC® Model 3324™ / 58 AMP is designed to provide clean, mobile aircraft power in a format suited for aviation ground support environments.

Benefits include:

• Mobile 24V aircraft power supply capability
• Designed for both starting and maintenance functions
• Continuous DC output when connected to AC power
• Portable design for ramp and hangar flexibility
• Extended use even when AC power is not available
• Suitable for cockpit power-up during service procedures
• Practical support for aircraft maintenance workflows

This combination makes the unit especially useful for operators who need both starting performance and aircraft system power in one piece of equipment.

FAQ

What aircraft is the Model 3324™ compatible with?

The START PAC® Model 3324™ is compatible with electrically started turbine and piston aircraft operating on a 24V system. This includes many turboprops, light jets, helicopters, and twin-engine piston aircraft. The unit outputs 28.5V DC, which helps simulate normal aircraft-running voltage.

Can the Model 3324™ be used without AC power?

Yes. The Model 3324™ includes an 84Ah battery pack, allowing it to operate independently in remote ramp or field environments where AC power is not available. When AC power is available, the unit can be recharged while also supplying maintenance power through its built-in power supply.

Will the Model 3324™ charge my aircraft’s onboard batteries?

No. The Model 3324™ is not designed as an aircraft battery charger. It is intended to provide external starting power and maintenance power only.

How many engine starts can I get per charge?

The 84Ah battery capacity is designed to support multiple turbine or piston engine starts per charge. The exact number of starts will vary depending on factors such as engine type, temperature, aircraft condition, and operating environment.

What AC input does the unit require?

The Model 3324™ accepts either 110VAC or 220VAC single-phase input. START PAC® recommends using a #12 gauge or larger extension cord. AC input cords are not included as standard, but START PAC® can build a cord to your required NEMA plug type and length for an additional fee.

How does the Model 3324™ help support turbine engine starting?

The Model 3324™ helps spool the turbine to a higher RPM before fuel introduction compared to a weak or partially discharged onboard battery. This can support faster and more efficient starts, helping reduce unnecessary stress on the starter and related engine components.
