Product spotlight – Red Box Load Banks

If you’re after a portable load bank, Red Box have been supplying for civil and military aviation for over twenty years in 28V DC, 270V DC and 400hz options. But what are they and what are they used for?

A load bank in its simplest form ensures that any equipment being used is able to run efficiently in the event of power outages, making them a hugely vital asset for companies across a wide range of industries. These devices generate a prescribed amount of electricity draw to test the reliability of electrical switching, generator output, cooling in a data centre etc. by imitating the equipment’s original load, making it impossible for a random current to occur, preventing potential power outages.

Although they don’t provide the power itself, load banks use the energy from the original supplier to protect, support and test the power source. Load banks are hugely important due to the fact that they replicate, prove and verify the real-life demands on critical power systems. There are a number of applications that require load banks, like our ground power units for example.

We have a wide range of analogue, digital and resistive load banks available, you can take a look here. However, if you have any further questions or if you’re still unsure on what you need, contact Red Box Aviation today on +44 (0)1799 512800 or via email at, where our Sales Team can discuss your individual requirements with you further.
