NR8805 Battery Charge & Discharge Comprehensive Tester

The instrument integrates the five functions of charging discharging monomer detection on-line monitoring and activation in one machine which greatly reduce the costs of enterprise reduce the labor intensity of maintenance personnel and provide comprehensive and scientific detection methods for battery and UPS power supply maintenance.
This machine adopts a new type of power consumption components manufactured by patented technology to achieve constant current discharge intelligent three-stage charging equalizing charge/ floating charge constant current/ constant voltage automatic conversion functions; real-time online displaying detecting recording the voltage of single or full set of batteries while storing or transmitting data to a PC; Large-screen LCD display full Chinese /English menu prompts easy to operate high degree of intelligence can set and control voltage current time capacity and other parameters automatically complete the test and monitoring of the various parameters of the battery group; Automatic discharging / charging can activate battery and extend battery life. After the charge/ discharge is completed the detected data can be directly uploaded to the PC via the RS232 interface or the data can be transferred to the USB flash driver at the scene. The supporting data processing software processes the data information of the put/charge collection analyzes the remaining capacity of the battery and generates various charts which provides a scientific basis for analyzing the battery performance.

Product characteristics
(1) It is a combination of charging discharging monomer detection on-line monitoring and activation. It is fully functional and can be used in one machine;
(2) Intelligent three-phase charging constant current discharge and real-time online detect the parameters of each cell;
(3) The power consumption element adopts alloy resistance which is safe no red-hot phenomenon and long life;
(4) The application of single-chip to USB flash driver data transfer technology solves the problem of large-capacity data storage.
(5) After charging / discharging data is transferred to USB flash driver or uploaded by RS232 interface the charts can be automatically generated after background processing and the battery performance is clear at a glance.
(6) Portable design convenient for high mobility users.
