The RPS-100 can return various real-time information of itself, including load current, temperature, existence, malfunction etc. The information not only can be used to evaluate the health condition of the RPS-100 itself, but also can be record to estimate the power consumption of the whole system, and an instant warning can be sent when abnormal power consumption occurs. Through the information, user can easily implement predictive alarm and fault alarm function for the system. In addition, the RPS-100 can also record the using time of itself by the communication module, which can be used as a basis for maintenance and replacement and estimate MTBF (Mean Time Between Failures). When the RPS-100 has reached the recommended service life, user can replace it early to make the power system more reliable and stable. The RPS-100 has a built-in load balancing function, so there is no need to add extra load balancing modules. In addition, the RPS-100 adopts a slot-type design, and it supplies hot swapping function, so when user replaces the RPS-100, there is no need to turn off the power system. In comparison to the traditional power supply, the RPS-100 saves the trouble of wiring, and it is simpler and safer.
