In response to the requirements of lots of digital DC power supplies in the industry, ICP DAS has developed the RPS series of redundant power supply, which not only adopts the N+1 parallel-connection and load-sharing technology to implement power redundancy, but also adds communication functions to enable that information of power supply can be monitored in real time. Through the communication functions, user can monitor the working status of the power supply of the whole factory in the monitoring center. When the power module is abnormal, it can be found and dealt with in real time. There is no need to send people to inspect and ensure that the power supply is safe. In particular, the equipment in some important industries such as finance, medical treatment and power plants needs stable power supplies to ensure that the equipment keeps working.
The RPS-4M/W2 has built-in Ethernet and RS-485 communication interfaces, which can not only monitor the operation status of the power modules in real time, but also instantly return various real-time information of the power modules, including load current, temperature, existence of the power module in the slots, malfunction of the power module, etc. The information not only can be used to evaluate the health condition of the power module 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-4M/W2 can also record the using time of each power module, which can be used as a basis for maintenance and replacement and estimate MTBF (Mean Time Between Failures). When the power module has reached the recommended service life, user can replace it early to make the power system more reliable and stable. The RPS-4M/W2 has a built-in load balancing function, so there is no need to add extra load balancing modules. In addition, the RPS-4M/W2 adopts a slot-type design, and it supplies hot swapping function, so when user replaces the power module, there is no need to turn off the power system. In comparison to the traditional power supply, the RPS-4M/W2 saves the trouble of wiring, and it is simpler and safer.


The RPS-4M/W2 can be used for power supply of remote IO equipment and control system. User can implement power redundancy and communication function through RPS-4M/W2. The RPS-4M/W2 can return power module information which includes load current, temperature, existence of the power module in the slots, malfunction of the power module in real time. So user can monitor the current and temperature of power modules in the control room. According to the information, user can set upper and lower limit alarm. When the range is exceeded, the staff will be notified to check whether there is any abnormal state of the machine. If a fault signal is detected, the staff will be notified to replace the power module immediately. Through long-term measurement and recording of various historical data of power supply, user can obtain normal values and upper and lower warning values by using statistical analysis techniques. Not only the stability of the power supply and failure warning can be controlled, but also the energy consumption and health of the electrical equipment can be analyzed. Therefore, the overall monitoring system will be smarter, more reliable and stable.
