HJDUM01 series of wall-mounted communication switching power supply system is the indoor and outdoor wall-mount- ed high-frequency switching power supply system developed by Huijue network for the actual use of communication equipment and the requirements of energy saving and emission reduction. This series of power supply can withstand wider AC input voltage range and wider operating temperature range, and can adapt to diferent applications.
This series of products is mainly composed of HJDMA10-48/50 series rectiﬁer module and HJDKD03 monitoring unit; AC-DC distribution integrated design, AC-DC separate design and walk monitoring module conﬁguration RS485 or Ether- net monitoring interface, with total load measurement function (no shunt measurement); rectiﬁer module air duct inde- pendent design, hot air directly discharged box body, do not afect the distribution part; with IP31 shell protection grade; reserved battery installation space, can be customized according to customer requirements lithium iron battery or lead-acid battery.
Product Features
• Modules allow wide range of input voltage variations (90 Vac~300 Vac)
• Adopt advanced topology circuit, realize so什 switch technology in wide load range, conversion effciency ≥96%
• The intelligent monitoring unit adopts advanced charging management mode to the battery, which is helpful to prolong the battery life
• The system has the function of effciency management, which can efectively improve the working effciency of the system and achieve the purpose of energy saving and emission reduction
• System RS-485 or TCP/IP network card interface to achieve local or remote centralized monitoring
• It has the function of measuring DC total power
• Rectiﬁer module in the system hot plug, all adjustment, operation are positive
• With over-current, over-voltage, over-temperature and other protection and alarm functions, the system has high reliability
• With multistage surge protector, can withstand 8/20 μs waveform 20 kA (maximum 40 kA) current shock
• Wider temperature range for adaptation, working temperature range -40 ℃~75 ℃
Application Scenarios
Suitable for all mobile communication base stations, integrated access network, distributed base stations and other indoor and outdoor occasions.
