We also offer different makes and models of load banks for any applications. Load Bank, a device which develops an electrical load applying the load to an electrical power source and converting or dissipating the resultant power output of the source, mimics the operational or “real” load that a power source will see in the actual application. As opposed to the “real” load which is served by the power source and uses the energy output of the source for productive purpose, the load bank serves the power source using its energy output to test, support or protect the power source.
