Start Pac 53300 28V DC Portable Aircraft Ground Power Unit for Rent

The Start Pac 53300 28V DC aircraft ground power unit is designed to power 24-volt aircraft systems and deliver up to 300 amps continuous at 28V DC. It is ideal for avionics testing, GPS programming, inverter operation, and onboard air conditioning during maintenance. Because it simulates aircraft operating voltage, it provides stable, clean, continuous power. This makes it well-suited for ground servicing of turbine aircraft.

No, the Start Pac 53300 is specifically designed for maintenance power, not for engine starting or battery charging. Its primary function is to supply continuous 28V DC power during ground operations. Using it as intended protects both the aircraft systems and the power supply unit. For engine-starting needs, a dedicated starting GPU is recommended.

Renting a GPU like the Start Pac 53300 provides flexibility for short-term maintenance events, AOG support, or temporary facility needs. It allows operators to access high-capacity 300-amp continuous power without the upfront capital investment required to purchase. Rental is especially beneficial for seasonal demand or one-time projects. For long-term, high-utilization operations, purchasing may still be the more cost-effective option.

By supplying 28V DC ground power directly to the aircraft, the 53300 allows operators to bypass the ship’s battery during maintenance. This helps preserve the onboard battery for engine starting only. Reducing unnecessary discharge cycles can extend battery life and lower replacement costs. It also minimizes electrical stress on critical components.

The Start Pac 53300 requires a 180V to 240V AC single-phase input. At maximum DC output, it draws approximately 40 amps at 220V AC. Confirming facility electrical capacity before delivery helps ensure a smooth setup. Our team can assist in verifying compatibility prior to your rental start date.

The unit includes overcurrent, overvoltage, and overtemperature protection to safeguard both the GPU and connected aircraft systems. If overloaded, the unit will trip off and automatically reset after a short period. These protective features enhance operational safety on the ramp or in the hangar. Built-in forced air cooling further supports stable performance.

Weighing approximately 42 lbs (19 kg) and measuring 20” x 8” x 13”, the 53300 is compact and easy to transport. Its lightweight design makes it practical for mobile maintenance operations. A removable 10-ft aircraft cable is included. Optional trolleys and wheel configurations are available for added mobility.

The Start Pac 53300 supports heavy-duty rubberized 3-pin aircraft connectors and CMC connector options. Heavy-duty aircraft cables and extension cords in multiple lengths are also available. Customized cable configurations can be provided for specific aircraft applications. Confirming connector compatibility before shipment ensures seamless integration.

The aluminum case features an environmentally responsible, low-VOC powder-coat finish that resists wear and harsh weather conditions. An optional all-weather cover is available for additional protection during outdoor use. These features make the 28V portable aircraft ground power unit suitable for demanding aviation environments. Durability is especially important for rental equipment used across multiple locations.

Renting the Start Pac 53300 is ideal for scheduled heavy maintenance, avionics upgrades, software installations, temporary hangar operations, or AOG support. Its 300-amp continuous 28V DC output provides dependable maintenance power without engine runtime. Rental allows operators to scale equipment needs without long-term storage or maintenance responsibility. It’s a flexible solution for evolving operational demands.
