Start Pac 53105M Portable Aircraft Power Supply

Start Pac 53105M is a portable 28.5 V DC power supply for maintenance work on 24/28 V aircraft. It delivers up to 105 A continuously from 180–240 V AC single-phase mains and powers inverters, avionics and GPS programming without drawing on the aircraft battery. The unit weighs 5.4 kg and has an attached 2.4 m aircraft cable.

Delivers up to 105 A continuously at 28.5 V DC, with no duty cycle.
Runs on 180–240 V AC single-phase mains and draws 14 A at 220 V AC at full output.
Weighs 5.4 kg including the aircraft cables and measures 400 × 115 × 133 mm.
Forced-air cooling plus over-current, over-voltage and over-temperature protection.
Powers inverters, avionics and GPS programming while bypassing the aircraft battery.
Not designed for engine starting or for battery charging.

Attached cable and connector

The 53105M has an 8 ft (2.4 m) aircraft cable permanently attached. Start Pac lists a red 3-pin aircraft connector as a spare part for this model.

Output and mains supply

The output is set to 28.5 V DC, the voltage of an aircraft running under power, and is rated for up to 105 A continuous current with no duty cycle.

The input is 180–240 V AC, single phase. At full DC output the unit draws 14 A at 220 V AC.

Use in maintenance

Start Pac designed the unit to power inverters, avionics, GPS programming and similar functions during maintenance. The aircraft battery is bypassed and spared unnecessary wear, so it stays available for engine starting.

Cabin air conditioning systems are high-draw loads and usually need at least 175 A.

Case and portability

The case is aluminium with a low-VOC powder coat. Start Pac describes the unit as small and light: it weighs 5.4 kg including the aircraft cables and measures 400 × 115 × 133 mm.

Manufacturer documents, provided for reference. Before installation or operation, make sure you have the current revision.

Can the 53105M start an engine or charge the aircraft battery?

No. Start Pac states that the unit is not for engine starting and not for battery charging. It is a continuous power supply for maintenance work, and Start Pac offers separate starting units and ground power units for other jobs.

Can it power an aircraft air conditioning system?

Start Pac notes that on-board air conditioning systems are high-draw loads that usually need at least 175 A. The 53105M supplies up to 105 A continuously, so it suits avionics, inverters and GPS programming rather than air conditioning.

What happens if the unit is overloaded?

It trips off and resets itself after a short period. Over-current, over-voltage and over-temperature protection are built in.

Which extension cords and spare parts does Start Pac list?

Aircraft-grade extension cords of 50 ft (15 m) and 100 ft (30 m), a custom cord length on request, a red 3-pin aircraft connector, a 50 A / 24 V power supply module and a 30 A circuit breaker switch. Custom colours are available on request.

Is the 53105M for 24 V or 28 V aircraft?

Start Pac names the model 53105-24/28V. The output is fixed at 28.5 V DC to match an aircraft running under power, and the data sheet describes it for powering 24 V aircraft systems. Fit depends on the aircraft voltage system and the mains supply at the site.
