Uninterrupted power supply is the basic protection for running all the equipment and network systems of constantly improved informationization and automation. Whether it is an AC or DC uninterrupted power supply system, a battery as a backup power supply in the system plays an extremely important role. At ordinary times, the battery is in the floating charge standby state, but once the AC power blacks out or other accidents occur, the battery will become the only power supply of the load.
It is known that the battery has a normal service life cycle, but it often has premature function failure due to such quality problems as material defects, structure defects or process defects, improper use, etc. To test the standby duration and actual capacity of the battery group and to ensure normal system operation, the checking discharge test is conducted on the battery group regularly or as needed according to the maintenance procedures of the power supply system, so that individual cell that has or is close to function failure can be detected in an early stage for replacement, thus guaranteeing the effectiveness of the whole battery group, or the expected life of the battery group is evaluated.
After years of R&D, the company has developed a series of highly intelligent battery charge and discharge testers with proprietary technology. This tester can be used as the discharge load in the battery off-line state, and realize the constant discharge of the set value by continuously regulating the discharge current. When discharging, the tester will automatically stop discharging when the voltage on the battery group terminal or the cell falls to the set lower limit value, or when the set discharging time is out, or when it reaches the set discharging capacity. In the meantime, the tester records all valuable and continuous real-time data during the process.
This tester system uses wireless relay access to the voltage monitoring information of cells, which is simple, safe, and accurate.
The tester has a very friendly man-machine interface, which not only enables a variety of settings and data checks under the menu prompt but also stores the discharge process data in the memory that can be archived to the USB flash drive through the data interface. Such data can be analyzed through special software in the upper computer to generate the curves and reports needed.
This instrument has a perfect protection function, with sound and light alarms and clear interface prompts.
