Part# 11-15563
MFR Model# TC3000/50-4


The TC3000A range is simply a combination between the battery powered start units and the mains powered continuous power supply units. When plugged into the mains these units will supply up to 600 amps continuously (dependent on the model). When unplugged they will give up to 7000 peak amps (dependent on the model).

The Red Box hand portable packs are some of the most powerful Hand Portable Packs available worldwide. Red Box uses the latest in military aerospace technology to achieve a very high power to weight ratio. These power packs are designed for starting of piston, turboprop or turbine aircraft and helicopters in the field or in remote locations and Red Box units may be carried safely on board all aircraft. The power packs are “all weather” units and being modular, can be used in single or dual format. They can be used or stored in any orientation, even inverted. Cells used are cleared as non-hazardous cargo for carriage in the aircraft. They are able to operate in extremes of temperature and have excellent standby characteristics. They are maintenance free and do not require cycling. They can be re-celled “on condition” at any Red Box service center in the world and are designed to give years of repeated service. In addition to aviation, these highly portable units can be used with Armored Fighting vehicles and Military equipment. They can be recharged from the automatic charging system, which is supplied in the package, or from any vehicle using a suitable interface.
