      How much temperature is suitable for Shanterups power supply?

      Shante UPS power supply in the use of the environment temperature can not be too high, here small edition reminds you that low temperature UPS also have an impact.



      The ambient temperature should not be too low. If the temperature is too low, for example, below 5 C, the amount of electricity released by the battery will be greatly reduced. In addition, it is also important to keep the UPS working environment clean. When UPS works in turbid environment, once the harmful dust floating in the air enters UPS, it will cause corrosion or short circuit to its internal devices, which will affect the normal operation of UPS and even damage UPS.



      Shante UPS power supply is an important power protection equipment which can provide continuous, stable and uninterrupted power supply. Maintenance is an important work in the use process. It can make the uninterrupted power supply work steadily and reliably, and prevent the loss caused by machine failure. In UPS equipment, besides cooling fans and circuit breaker switching components, there are a large number of solid-state electronic devices. After a long period of use, these electronic devices will not be worn by machines, but they are vulnerable to the external environment. Therefore, it is necessary to do a good job of temperature control in daily maintenance work.



      1. Maintaining an Appropriate Environmental Temperature



      Environmental temperature is an important factor affecting the life of batteries. The optimum ambient temperature required by battery manufacturers is between 20 and 25 degrees Celsius. Although the discharge capacity of batteries is improved with the increase of temperature, the cost is that the life of batteries is greatly shortened. According to the test results, once the ambient temperature exceeds 25 C, the battery life will be reduced by half for every 10 C increase. At present, UPS generally uses maintenance-free sealed lead acid, and its design life is generally five years, which can be achieved only under the environment required by battery manufacturers. If it fails to meet the required environmental requirements, its life span will vary greatly. In addition, the increase of ambient temperature will lead to the increase of chemical activity inside the battery, which will generate a lot of heat energy, and in turn will promote the increase of ambient temperature. This vicious cycle will accelerate the shortening of battery life.



      II. Periodic Charging and Discharging



      The floating charge voltage and discharge voltage of Shanterups power supply in the United States have been adjusted to the rated value at the time of leaving the factory. The discharge current increases with the increase of the load. The load should be adjusted reasonably in use, such as controlling the number of electronic devices such as microcomputers. Normally, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the battery will not be excessive discharge.



      Because UPS is connected with municipal electricity for a long time, it will be in floating charging state for a long time in the environment of high quality power supply and few blackouts. Over time, it will lead to the decrease of the activity of the conversion between chemical energy and electric energy of batteries, accelerate aging and shorten the service life of batteries. Therefore, the discharge should be completed every 2-3 months, and the discharge time can be determined according to the capacity and load size. After discharge of a full load, recharge for more than 8 hours according to regulations.



      3. Utilizing Communication Functions



      At present, the vast majority of large and medium-sized UPS have the operability of communication with microcomputers and program control. The corresponding software is installed on the computer, and UPS is connected through serial/parallel ports. By running the program, the computer can communicate with UPS. Generally, it has the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Through information inquiry, information such as input voltage, UPS output voltage, load utilization ratio, battery capacity utilization ratio, in-machine temperature and power frequency can be obtained. Through parameter setting, basic characteristics of UPS, battery maintenance time and battery exhaustion alarm can be set. Through these intelligent operations, it greatly facilitates the usage and management of Shanterups power supply in the United States.



      IV. Replacing Waste/Battery in Time



      At present, the number of large and medium-sized American Shanterups power supply varies from 3 to 80, or even more. These individual batteries form battery packs through circuit connections to meet the needs of UPS DC power supply. In the continuous operation and use of UPS, due to the difference in performance and quality, the performance of individual batteries is degraded and the storage capacity is not up to the requirements and damage is inevitable. When one or more batteries in the battery pack are damaged, maintenance personnel should check and test each batteries to eliminate damaged batteries. When replacing new batteries, we should strive to purchase batteries of the same type as those of the same manufacturer. It is forbidden to mix acid-proof batteries with sealed batteries and batteries of different specifications.
