The renovation program in China Telecom communication telegraphy 北京动力源科技股份有限公司 Beijing Dynamic Power Co., Ltd. 入围 2010 中国交通创造力企业 TOP50 listed as top 50 creativity enterprises in China 2010 --- Solution of DC remote power supply indoor/outdoor distributed system The main application area: 3G indoor , external covering the RRU, ONU, WLAN, optical terminal, micro cell ,trunk Amplified etc. Features: Can operate for a whole day with high adaptability (such as shafts, elevators, power distribution room, the roof of the gin pole, tower, etc.) Easy to choose the site location, without affection by mains. Saving the extra cost of AC power and easy to be managed Excellent safety protection measures. Greatly improve the network quality, the network is still available even power off. Solution of DC remote power supply Convert the -48v power of macro base station to 215~410v via DC/DC boost and transfer the power to far end through cables. Then the voltage will be converted to -48v to load via DC/DC buck. The cables are not grounded. DC / DC buck to -48V DC / DC boost 215 ~ 410V DC (ungrounded) Distal module Local power OPGW / Cables -48v Macro station base RRU DC remote power supply solutions for signal cover of expressway and railway - Base station Remote power Eq Base station Remote power equipment room 215 ~ 410V DC ( ungrounded) Base station Loc Llocal power Base station Base station Remote power Remote power Remote power The cost of cables is effectively decreased by chain type power supply B Keep the power uninterrupted even one rout is faulted BBU local power The load is divided into two parts, which effectively reduce the load on unilateral wire and shorten the wire to reduce the coat.

The local end output is ungrounded, so no loop tank and electric shock if people touch the monopole. ②. With automatic detection functions for the status of open circuit, short-circuit, earth leakage, strong electric lap, the local end will cut off the high-voltage output in 30ms after detecting the signal to avoid personal injury. ③. Rated 20KA lightning is connected to the output of local end and the input of remote end to avoid the surge impact of the remote transmission line to the equipments. Product advantage ①. Wide output voltage range (215V-410V), the output voltage of local end can adapt automatically. The setting voltage of local end controller is the input voltage of remote power. The local end will adjust its input voltage automatically according to the cable loss. ②. The local end module is more environmental protection with sleep function. ③. The local end module adopts N+1 redundancy, which is also available for distal end, to ensure the safety power supply of system. ④. There are variety of ways for recovery the open circuit, short circuit, leakage and strong electric lap protection for the system, including automatically, manually, which are applicable to variety of sites and improve the maintenance efficiency. ⑤. The remote power can connect with 220VAC mains and high voltage 215V~ 410VDC and mains first. The working mode of local power supply and remote spare electric is available for system, this ensures power system usability and high efficiency of power supply. 中国移动通信 China mobile 中国电信 China Telecom 中国联通 China Unicom
