Intelligent Monitoring Solution for High-Voltage DC Precise Distribution in IDC Machine Room


With the acceleration of 5G large-scale commercial and fixed-line users, the corresponding landing of 5G various application scenarios will lead to an exponential increase in the type and quantity of data, and the demand for data centers will reach an unprecedented level. The construction of IDC (Internet Data Center) computer room supporting power supply plays a key role in the development of the data center. At present, the uninterruptible AC power supply system (UPS) is widely used in IDC machine room, but at the same time, more and more projects adopt the 240 V high-voltage DC power supply scheme. The 240 V high-voltage DC power supply system is mainly composed of rectifier cabinet, DC cabinet, battery, DC distribution cabinet and column head cabinet. Compared with UPS power supply system, high-voltage DC power supply system has the advantages of less conversion links, high efficiency, high reliability, convenient maintenance and long service life.

The Elecnova BCM201 high-voltage DC precise power distribution monitoring unit can achieve high-precision power monitoring for each circuit in the DC array cabinet, and achieve refined energy consumption management. At the same time, the insulation monitoring module can monitor the insulation performance of the entire DC system to the ground. The DC precise power distribution single metadata can be uploaded to the dynamic monitoring system through digital communication, providing reliable guarantee for operation management.
