The outdoor cabinet is a closed iron box. When the cabinet is exposed to the summer sunshine, the solar radiation heat will be transmitted into the cabinet through the sun drying surface. The temperature inside the cabinet will rise, which will cause the rectifier module or inverter module of the product and UPS will be shutdown due to over temperature protection. At the same time, the temperature inside the cabinet is too high, which is very unfavorable to the battery. No matter the adsorption type or the colloid sealed lead acid battery will cause the loss of water in the battery medium due to the high temperature. When the battery medium is lack of water, the conversion efficiency of the battery will decrease, and the failure of the battery is not output.

First, the demand for UPS energy saving and environmental protection is increasing. In the situation of international oil price volatility and global energy shortage, material recycling and no pollution to the environment, will become the future development direction of power supply products, with the continuous improvement of the level of information, and in the construction of the data center more emphasis on “green” concept. Especially in the UPS innovation technology and the application of air conditioning in the machine room, more and more modular design is adopted. The modular design of UPS and refrigeration system can avoid energy consumption. By modularized flexible expansion, we can reduce user’s investment in equipment and save energy.
Secondly, the UPS distribution market still occupies the main position. The main body of the distribution market consists mainly of UPS dealers and industry agents, and the UPS dealers here include professional power suppliers and IT channel dealers. According to the distribution of UPS market in China, the share of the distribution market is still more than 50%, which is the main channel for UPS sales. With the rapid development of domestic economy, the serious shortage of electric energy, the further popularization of IT applications, and the rapid rise of public consumer electronics, the demand of customers in the middle and low end market is very large. Although the middle and low end market needs to face relatively dispersed customer groups, the demand for intermediate and low-end industries is not seasonally fluctuated, but relatively stable.
Finally, UPS is becoming more and more domestically made. In the future, the competition environment of domestic UPS market will become more and more standardized and benign. Many manufacturers that fail to guarantee quality and service and will not be guaranteed will be phased out by the market. China UPS brands not only complete the import substitution, but also gradually realize the internationalization.

It is mainly used in the place where the load equipment requires high quality of the power supply. Such as electric power telecontrol, RTU, power carrier, monitoring, program control switch, computer room, network, billing, server and accident light place and so on. If the AC input is cut off, the power supply will be provided by the power system, post office system’s DC screen or external battery cabinet through the inverter, will provide a long and continuous power supply for the load equipment. If the DC screen is broken down, the inverter is overloaded of failed, the system automatically switches to the bypass power supply, which ensures the continuity. In a place with DC power, the inverter power supply is used to supply the important load equipment with the following advantages:
1.Avoid the repeated investment of the battery group, reduce the maintenance of the system, and reduce the operating cost of the system 2.The DC screen of power system usually adopts VRLA battery. Because DC screen has high reliability and long life (10~15 years), the reliability and life of DC screen can be greatly improved. The battery in the conventional UPS often has no maintenance and no monitoring, it is easy to appear in the case that the battery has long been damaged but can not be found in time. 3.Because of the large capacity of the DC screen, it can provide a long enough AC power supply time after the power grid is cut off.
Lightning protection system: the damage caused by lightning strikes is common, and there are numerous losses to the production. In order to reduce the losses caused by lightning, the power supply system should be equipped with an advanced lightning protection unit, which effectively prevents lightning from damaging the equipment. The input circuit can effectively, reliably and quickly absorb the pulse voltage of the input terminal, so as to ensure that the output power equipment is not affected.
AC and DC isolation inverter technology: DC system uses high frequency and high efficiency DC isolation converter, so that the input and output electrical is isolated, effectively prevent electric shock accidents, make the DC system grounding problem very simple, and the second grounding is more convenient. The active filter technology used in DC greatly reduces the noise of the system and improves the input voltage of the DC system. The DC/DC high frequency isolation converter is connected to the inverter with high voltage and APFC high voltage in parallel. So when the power supply is normal, the inverter is supplied by AC rectifier and the DC is in the state of hot backup. When the power interruption or abnormal AC input, protect the normal startup, DC isolated by the DC/DC transform to the inverter power supply, inverter into 220V sine wave output voltage, so whether it is normal or not, the power supply system is through the inverter power supply to the load, so it is always the output AC voltage and frequency stabilization the voltage of 220V, realize the uninterrupted work.
Sinusoidal pulse width modulation technology: the whole machine adopts the full high-frequency design, which has the advantages of strong anti-interference ability, high precision, high frequency stability, small distortion, high efficiency, small volume and light weight. The inverter main circuit uses advanced PWM and three way overcurrent detection technology, which greatly improves the reliability of inverter and makes the instantaneous load controllable due to nonlinear load, and has good output protection characteristics.
Remote monitoring: with remote monitoring signal output, the real-time operation state of the inverter (DC input, AC input, inverter operation and fault signal) can be sent to the control center through the switch input port of the data acquisition system.
Hot standby system: any 2 /3 stations can be barred into 2+1 or 3+1 hot backup system, the built-in automatic connection program, any one barge connection output, it is more convenient to press according to the installation, and the system is more reliable.

The equipment in IDC is very important. Servers, computers, monitoring and so on, all above need to be ensured normal power supply, especially the transmission and reception of data on the network. These are all used for servers, so the reliability of servers is guaranteed. Sudden power failure, instant voltage and current at incoming calls will be very high. Some precision equipment can be burnout through this instant impact. UPS has voltage stabilizing function and its existence protects the safety of these devices under such circumstances.The process of some work can not be blackout, such as operation, test, scientific research, charge and so on. These places must be protected by UPS power supply. The role of UPS power is to enable us to have enough time to store data in the case of some urgent outages, and also that is UPS. It is also the UPS’s voltage stabilizing function that can effectively protect the electrical safety of the equipment.
