12V/24V & 14v/28V  switchable start Units

     

These high powered dual 12v/24v and 14v/28v units are designed to offer maximum power to weight ratio. With the Red Box ‘switch cable system’ these switchable start units can outlive similar products on the market by up to 100%. Red Box dual voltage systems comprise of 2 batteries cleverly configured to ensure that an equal amount of current is drawn from both cells, regardless of whether you are using the unit in 12v/14v or 24v/28v mode. Many other systems on the market will use only one battery when in 12v or 14v mode. Built to Military and Aviation standards, you can be guaranteed of the quality of this product.

Units are available in both lead acid and lithium. The lithium units are more expensive but if weight is an issue then these units are the answer.

All our switchable start units come with a separate charger, assuring the life of your pack. It is the pack that will get the continual use, keeping the charger separate protects it. The inbuilt LED display will ensure you always know the status of the pack. When the batteries within the unit finally come to the end of their life, simply contact a Red Box distributor for a replacement set, all batteries are designed to be easily replaceable.

The Red Box range comprises of start units, combination of starting capability and continuous power at continuous power at 28 V or for more power demanding aircraft our transformer rectifier units or frequency converters are available.

For situations where units cannot be charged by a mains electric supply our Self powered GPUs called HybREDs are invaluable. They are an alternative to the start and continuous units powered by batteries as these units need to be charged before use. Contact our sales team who specialise in finding the right equipment to suit each requirement.
