Load banks are an important asset in any industry, as they ensure the operation of equipment in the event of a power outage. Specifically, load library renting allows you to create a load similar to daily use and test the operating efficiency of the power supply. By simulating the raw load, there are no random or unpredictable currents. A load group is an contained system unit that integrates controls and accessories into an installation location. The power supply will provide power, but the load group uses this energy to protect and support the power supply as well as test it.
