Demand of telecom network for outdoor integrated power supply

In the increasingly fierce competition in the telecom industry nowadays, the telecom operators pay more attention to the rapid development of the business and the quality of the entire network. As the heart of the whole network, the network energy system is an important part. Operators need to have good cost performance, adapt to different situations, reliable and stable telecom power supply solution, so as to effectively solve the bottleneck of large-scale telecom construction and development, implement national energy conservation and emission reduction policies, and realize the high availability of the network. Under such circumstances, the establishment of a complete “network, energy integration” of the telecom power supply room, is the general trend.

Requirements of telecom network construction for power system
*The rapid construction, modular design;
*Stable and reliable;
*Green energy conservation, in line with the national energy saving policy;
*Coverage in all directions.

SOROTEC telecom power systems can meet the above 4 core requirements effectively. Compared with the traditional base station, the distributed base station has obvious changes in physical structure, power supply mode, engineering maintenance and protection, and the corresponding power support system should also adapt to this change.
*More power saving. The wireless side topology of the distributed base station becomes 1:N from the baseband and RF 1:1 relationship, accordingly, the power supply node is also changed from less to more, from a set of transmission base stations to multiple sets of power supply system.
*The physical structure of telecom base station has changed from traditional cabinet type equipment into modular, embedded, wall mounted and other forms, and the power supply scheme tends to be diversified.
*Centralized power supply becomes decentralized power supply. The wireless device connection changed from the plurality of antenna and antenna coupling of the BTS group into a simple transmission line and power line and antenna line, power supply scheme changed from the centralized power supply mode into the traditional distributed power supply.
*The change of engineering maintenance interface. The distributed power supply extends the power engineering maintenance interface to three segments, the BBU power supply section, the far distance power supply section between BBU and RRU, and the RRU power supply section.
*Lightning protection difficulty increases. The distributed base station has DC pull and DC RRU side power supply, which increases the pressure of DC lightning protection and remote AC lightning protection.
*Anti-theft difficulty increased. The increase of power line power supply and outdoor equipment will increase the difficulty of anti-theft.

SOROTEC HW9110E 1-10KVA High Frequency Outdoor Online Hanging UPS (outdoor ups systems,ups outdoor)

1.SOROTEC Outdoor Intelligent High Frequency Online UPS provide continuous pure sine wave AC power supply for
outside communications / network equipment.
2.Double-conversion online design, high temperature resistant, anti-cold, sealing level for IP55; With the wide range of input voltage and frequency of input window (- 45% +35% rated voltage and ± 10% rated frequency), in many remote areas of China after a severe test of the grid.
This outdoor UPS system is commonly used in the corner of the city, remote roads, mountains, bad environment, such as high temperature (+50 °C) / low temperature (-40 °C), severe dust, moisture, rain, mist erosion, very poor power quality (voltage longterm higher than 260V or less than 160V, frequency abnormal change) in the area.

Correct selection of backup time for UPS

图片
UPS backup time is generally a problem concerned by customer in the purchase process. Usually most people prefer to choose the  UPS  which power backup the longer the better, in fact, this is not correct. We must firstly clear that the seller will usually have standard type UPS and long-acting UPS. Standard type UPS with built-in battery, after a power interruption can supply power to the load equipment in general for a few minutes to tens of minutes, of course, the length of time depends on the load. Long acting UPS can not only meet the power requirement of load, but also meet the requirements of customers and work types and so on, so the long-term UPS is usually equipped with an external battery pack. If the client is not particularly strict to the work condition of the load, and the power of the load is not particularly large, usually with standard type UPS would be enough. Because the choice of long backup time UPS is bound to increase the number of battery groups an...

126th Canton Fair

图片
On Oct 15th 2019, as one of the most important trade promotion platforms for Chinese enterprises to expand the global market, Canton Fair in Guangzhou focused on highlighting innovation driven, and “independent brand” became a high-frequency word of Canton Fair. Xu Bing, a spokesman for the Canton Fair and deputy director of the China Foreign Trade Center, said that the domestic and foreign environment faced by China’s foreign trade development this year is more complex and uncertain. The majority of exhibitors accelerated quality improvement and innovation, and continued to make efforts in technology research and development, product innovation, brand cultivation, etc., with high technology, high quality, high added value and independent brand products emerging. Many independent innovative R & D products are welcomed by the market. At the same time, purchasers are less sensitive to price and pay more attention to the technology, brand, quality and service of products. In ...

How to maximize the efficiency of your UPS

图片
1.Use of AC voltage regulator After using  UPS power supply , there is no need to add AC voltage regulator. If it must be added, it should be added to the front level of UPS, that is, the mains power first passes through the AC voltage regulator, then through the ups, and then to the load. 2.Battery balanced charging skills At present, valve regulated lead-acid battery (VRLA) used in many ups power supply is called maintenance free battery from the beginning, which gives users a misunderstanding that it seems that this battery is durable and does not need maintenance at all. Under this kind of misleading, many users have not carried out maintenance and management since they installed the battery. When the battery in UPS power supply meets the following conditions, the battery shall be charged evenly: when the terminal voltage is lower than the specified calibration voltage due to excessive discharge. For 12 V small sealed lead-acid batteries, the discharge calibration voltage is...
