Benches Hardware Reference 1 General Presentation Different types of load banks and benches Load banks are constructed of switched loads, used for electrically loading electric equipments for testing. When the loads are fixed loads, they are considered simple resistor assemblies, in open frame constructions or in resistor enclosures; examples of these assemblies are provided in the documentation on the different types of resistors (wirewound resistors, edgewound resistors and woven resistors). Depending on their use, benches are split into 4 categories : • battery discharge testers are used to...
