HJDUM01 Series: Wall-Mounted Telecom Switch Power Supply System
Outdoor and indoor wall-mounted high-frequency switching power HJDUM01 series of wall-mounted communication switching power supply system, the independent research and development by Huijue network, for the communication equipment actual use and energy-saving requirements of emission reduction. This series power input voltage, operating temperature range can be wider, can adapt to diferent applications.
- 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 an advanced charging management mode to the battery, which is helpful to prolong the battery life.
- The system has an effciency management function that can better improve the working effciency of the system to promote the purpose of energy saving and emission reduction.
- The system RS-485 or TCP/IP network card interface to realize a local or remote centralized monitoring function.
- Able to measure DC total power.
- System rectifier module hot plug, all adjustment, operation are positive.
- High system reliability with over-current, over-voltage, and over-temperature protection among others. Also, alarm functions.
- With multistage surge protector, can bear 8/20 μs waveform 20 kA (up to 40 kA) current shock.
- Much wider adaptation to temperature: working temperature ranges from -40 ℃ ~ 75 ℃.
The differentiated power backup equipment is such a power distribution device that possesses functions like controlling the on-off and power metering of each household/branch. This will be able to achieve differential management over the communication base station load according to such factors as backup power time, battery voltage, and battery power in response to differentiated backup power requirements of different customers and different equipment in the base station.
The differentiated product lines, on the other hand, call base station backup equipment subuser control equipment, branch control equipment, smart power distribution unit, or smart switch.
- Intelligent distribution unit: It can control the on and off of each household as a whole and can meter the electricity of each household accurately, thus realizing intelligent, standardized, and differentiated control equipment for the communication load of each household. It can be installed and fixed in the following two forms: Embedded and Wall mounted.
- Smart switch: It can independently control each branch of DC output and perform some functions, such as precise electric energy measurement for every DC output branch, so as to realize the intelligence, standardization, and differentiation power backup control for every communication load equipment. It can be installed and fixed in the form of guide rail.
Suitable for indoor and outdoor base stations of all mobile communication, integrated access network, and distributed base station.
