Distributed Power System Introduction Distributed Power System DPS

Distributed Power System Introduction Distributed Power System (DPS) is a new generation power solution that specialized for compact site. It consists of DC module, AC module & battery module. It supports pole-mounted and wallmounted. DPS can be widely used for macro site, small cell and remote RRU. DPU 40 D: DC module, converts AC/HVDC to -48 V DC, supplies 3 branches of DC output and 1 branch for battery DBU 20 B & DBU 50 B: battery module, provides reliable backup energy Features l Simple Deployment • Fast installation, 1 hour by 1 person • Multiple input modes: AC/HVDC (DPU 30 D & DPU 40 D) l Easy O&M • Mobile APP (based on Bluetooth), Net. Eco • Fan-free design, 4 -6 years routine maintenance-free l Reliable Power Supply • Lithium iron battery, IP 65, working temperature -40ºC to +55ºC Scenarios l RRU/AAU remote site l Easy Macro Site l Lamp. Site l Atom. Cell (hot-spot / blind-spot coverage) l Enterprise telecom scenario DC Load Scenario

Remark: 1. Affected by the external environment factors, such as temperature and duration of transportation and storage, the rated capacity may fluctuate by ± 5% 2. Operating environment definitions: Class C-Sea environments or outdoor land environments (with simple shielding measures) near pollution sources. If a site is near a pollution source, it is at most 3. 7 km away from salt water such as the sea and salt lakes, 3 km away from heavy pollution sources. such as smelteries, coal mines, and thermal power plants, 2 km away from medium pollution sources such as chemical, rubber, and galvanization industries, or 1 km away from light pollution sources such as packing houses, tanneries, and boiler rooms. Class D-Environments within 500 m away from the seashore. Class D environments are special Class C environments 3. Grid classification standard: 1 st rate grid: power outage < 10 hrs per month; 2 nd rate grid: power outage < 10 hrs per week; 3 rd rate grid: power outage 2 -8 hrs per day 4. The recommended storage temperature is 20ºC to 30ºC, battery life would be reduced if stored in high temperature (The recharging interval should be 12 months under the condition of storage temperature < 30ºC, and 8 months under the condition of 30ºC < storage temperature < 40ºC). 5. RS 485 interface supports telecom protocol/Mod. Bus, surpport Net. Eco / U 2000 Internal Communication: DPS supports in-band communication with 5 th generation Huawei RRU.
