Load Banks


What is a Load Bank?

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. A Load Bank is intended to accurately mimic the operational or "real" load which 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 which includes both load elements with control and accessory devices required for operation.

Where 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.

Load Bank Types


These Load Banks are used with Engine Generators, Battery Systems, UPS Systems, Inverters, Ground Power Units, Auxiliary Power Units, Aircraft Power Generators, Wind Generators, and Hydro Generators.


A "reactive" load includes inductive (lagging power factor) and/or capacitive (leading power factor) loads.


Inductive loads, the more common type, consist of iron-core reactive elements which, when used in conjunction with a resistive load bank, create a lagging power factor load. Typically, the inductive load will be rated at a numeric value 75% that of the corresponding resistive load such the when applied together, a resultant 0.8 power factor load is provided. That is to say, for each 100KW of resistive load, 75KVAR of inductive load is provided.


A capacitive load bank is similar to a reactive load bank in rating and purpose, except that leading power factor loads are created. These loads simulate certain electronic or non-linear loads typical of telecommunications, computer or UPS industries.

Water Cooled

For environments that require 'pin drop' quiet operation, the Simplex LBW Load Bank offers a highly attractive alternative to traditional air-cooled units.
