Communication Equipment Power Wall System – HJDUM01 Series
The series of HJDUM01 wall-mounted communication switching power supply system is an indoor and outdoor wall-mounted high-frequency switching power supply system independently developed by Huijue network for practical application of communication equipment and demand of energy conservation and emission reduction. A wider range of AC input voltage can be borne by this kind of power supply and a wider operating temperature range, adapting to different applications.
HJDUM01 wall-mounted communication switching power supply system is a series product of indoor and outdoor wall mounting high-frequency switching power supply system developed by Huijue Network according to the actual use of communication equipment and the requirement of energy saving and emission reduction. The series of power supply can withstand wider AC input voltage range and wider operating temperature range, and adapt to diferent applications.
This series of products is mainly made up 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. The air duct of the rectifier module is designed independently, directly discharging the hot air from the box body without affecting the distribution part. With IP31 shell protection grade, there is reserved space for installing a battery, which can be made according to customer requirements into lithium iron or lead-acid batteries.
- 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 the advanced charging management mode to the battery, which is helpful to prolong the battery life.
- The system has the function of efficiency management and effectively improves working efficiency of the system to achieve energy saving and emission reduction.
- RS-485 or TCP/IP network card interface is provided for the system for local or remote centralized monitoring.
- It has DC total power measuring function.
- The rectifier module of the system is hot plugged; all the adjustment and 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 ℃.
Suitable for all mobile communication base stations, integrated access network, distributed base stations and other indoor and outdoor occasions.
