The Rack Mounted Load Bank adopts a standardized cabinet integrated design, which strictly complies with the installation size standards of industrial cabinets and can be directly adapted to the integrated installation of standard server cabinets and electrical control cabinets. The equipment has the advantages of small size, high integration and regular wiring, and supports cascading combination of multiple equipment to realize modular load expansion. It does not require independent space occupation and adapts to the intensive and standardized operation and maintenance mode of computer rooms. It is mainly used for batch aging testing and daily operation and maintenance detection of built-in power supplies, small UPS and modular power supplies in communication computer rooms, data centers and industrial control cabinets, and is a core supporting equipment for intelligent and intensive power testing.
