As to the loading board part, many design methods are introduced, such as master-slave communication, input signal detection, status displaying, manual action, power supply and so on.

Data acquisition and monitoring system of loading test of high power UPS modules are investigated and designed. The principle of the system, hardware structure and software design are given.

In order to solve the above problems, a study on the DC-DC power modular of the loading terminal was conducted and a new design plan of the intrinsic safe DC-DC isolated power modular was provided.
