With the continuous development of IT technology, higher requirements are faced by electrical reliability and delicacy management of data center, and large-scale & high-density electricity has become the development trend of data center. Therefore, it’s very important to carry out real-time monitoring on power incoming/outgoing lines of data center array cabinet. What’s more, electricity cost accounts for a large proportion in O&M cost of data center, and using energy in a more economical and effective way has become a responsibility of related enterprises.
A precision array cabinet provides safe and reliable power supply to server appliance of data center energy terminal, and precision power distribution units provide high-precision measurement data for data center energy monitoring system. As a result, power quality data are reflected in real-time through human-computer interface. Moreover, such data are uploaded to background dynamic environment monitoring system through digital communication, realizing real-time monitoring to the whole power distribution system. At the same time, precision power distribution units can provide energy metering function and realize refined energy efficiency analysis of power distribution and rack, to provide basis for the optimal regulation of power distribution network and server running energy efficiency, thus achieving the purpose of energy saving and consumption reduction.
