Load banks are used in generator load testing, verifying, and exercising a generator’s ability to handle an electrical load and are a key element in any backup power system. Load banks can also provide automatic load sensing, where the load bank automatically adjusts to fluctuating power loads and keeps the generator running optimally. Global Power Supply offers new and used load banks in sizes from 100 kW and larger. We are an authorized dealer for several of the top load bank manufacturers in the industry.
