Start Power Units

12v / 24v / 26v / 28v DC Aircraft Start Power Units

The Red Box offer a comprehensive range of battery-powered aircraft start GPU’s are the best option for almost any DC aircraft. These are designed to start aircraft from the very smallest up to the largest business jets. We supply a full range of voltages (12V, 24V and 28V) with a multitude of power capacities available.

Here is a brief outline of what you should be considering:

It is important to choose not only the right start power unit for your aircraft, but also the right unit for your operation. Some customers only want a unit to start in emergencies and some will be using it multiple times a day. Although Red Box units are designed to initially power aircraft, some customers require a small amount of continuous power as well. Please discuss your requirements with our sales team; they have the experience to recommend the correct unit for your needs.

For some small aircraft the start power unit requirement is for a 12V unit. We manufacture 12V units in 3 sizes, although any aircraft that needs 12V only needs to use our smallest RB25A 12V unit, the larger units are only really for multiple starts.

As standard, most DC powered aircraft only need 24V DC to start. The ground power port normally indicates 28V DC, but this is for the continuous power requirements. The onboard battery is 24V therefore you only need 24V. We have a large number of 24V aircraft units available ranging from small hand portable units to large trolley cart units. If weight is an issue we produce the same range utilising lithium battery technology. If you are unsure which start power units are required please contact one of our sales team and they will be more than happy to help you.

We also manufacture a number of 28V DC aircraft power units too. In most cases this is only to provide customers with peace of mind as most aircraft will start from 24V DC. Although there are a few aircraft that are volt sensitive and need a 28V DC start system. Our sales team will help you choose the right unit.

If you are looking to be able to continuously power your aircraft to practice using the avionics or to perform updates to the system then our RBSC and RBPS range provide this facility for you. A dual voltage power unit can be used to power either a 14 volt or 28 volt aircraft. Sometimes a combination of start and continuous power in one unit is required. In remote locations where mains power is not available the Self powered GPU will allow both of these forms of power.
