A load bank is a device which develops an electrical load, applies the load to an electrical power source and converts or dissipates the resultant power output of the source.
The purpose of a load bank is to accurately mimic the operational or “real” load that a power source will see in actual application. However, unlike the “real” load, which is likely to be dispersed, unpredictable and random in value, a load bank provides a contained, organized and fully controllable load.
Consequently, a load bank can be further defined as a self-contained, unitized, systematic device that includes load elements with control and accessory devices required for operation.
Whereas the “real” load is served by the power source and uses the energy output of the source for some productive purpose, the load bank serves the power source, using its energy output to test, support or protect the power source.

Famous quotes containing the words load and/or bank:
“Rich are the sea-gods:Mwho gives gifts but they?
They grope the sea for pearls, but more than pearls:
They pluck Force thence, and give it to the wise.
Every wave is wealth to Daedalus,
Wealth to the cunning artist who can work
This matchless strength. Where shall he find, O waves!
A load your Atlas shoulders cannot lift?”
—Ralph Waldo Emerson (1803–1882)
