Red Box Aviation is pleased to offer a number of 28V DC power supplies, which are perfect for aircraft that are volt sensitive and needs a 28V DC start system.

In most cases the 28V option is only to provide customers with peace of mind as most aircraft will start from 24V DC. However, you can be safe in the knowledge that choosing a higher voltage power supply will be more than enough for your aircraft’s requirements.

It is important to choose not only the right start power unit for your aircraft, but also the right unit for your operation. So, if you are unsure which is the right unit for your needs simply contact our team today on +44 (0)2380 254285, or via email at sales@redboxint.com and we will be happy to help.
