Battery charge and discharge tester intelligent charging and discharging the battery tester tester I. Product Overview RTKR-990 intelligent charge-discharge tester set charge, discharge, single detection, online monitoring and activation Observing the body of a machine. Reduce business costs, reduce labor intensity maintenance personnel for maintenance of batteries and UPS power supply provides a comprehensive scientific testing methods. The machine uses the new power devices, patented technology to achieve constant current discharge, intelligent three-stage charging, Equalize / Float, constant current / constant voltage automatic conversion; live online polling of each battery cell or a whole group voltage, real-time online display, testing, recording a single section or the entire group of the battery voltage, while the data is stored or transmitted to a PC; large-screen LCD display, full Chinese menu prompt, simple operation, high degree of intelligence, can be set set and control the voltage, current, time, capacity and other parameters, auto-complete battery of various test parameters, monitoring; automatic discharge / charge, the battery can be activated to extend battery life. Charge / discharge is completed, test data can be uploaded directly via RS232 interface to a PC or a data dump site to the U disk; supporting data processing software for the discharge / charge data collected for processing, analysis, remaining battery capacity to generate each kinds of charts, for the analysis of battery performance to provide a scientific basis. Second, product technical requirements), the product features: (1) LCD screen display, full Chinese menu prompt, simple operation, high degree of intelligence, you can set the voltage, current, time, capacity and other parameters, auto-complete set of batteries of various parameters testing and monitoring. 2 real-time online monitoring: real-time online monitoring, display all the test data: current, battery voltage, single cell voltage, time, capacity, etc., while the data is stored and transmitted to the PC, display and print various charts. 3 automatic discharge Charge: Set the discharge / charge current to limit the length of high capacity and voltage, the lower limit may be a discharge cycle, the charging process. 4 Battery activation function: Set discharge charge cycles, the battery pack can be activated. 5 automatic shutdown feature: any one of the following conditions are met automatically stop the discharge / charge: time, the capacity to, as well as single battery protection voltage to the battery voltage protection to the entire group. 6 protection: if abnormal voltage occurs, automatically stop charging or discharging. 7 voltage, current display calibration correction values: total principal calibrate the battery voltage, current and single cell voltage. 8 U disk data transfer storage functions: charging, discharging, after the activation of the automatic discharge rechargeable battery or can dump the collected data U disk, U disk and then from the discharge / charge collected data dump the PC , after the supporting data processing software, display, print charts. To determine the entire group or the merits of single cells provide a scientific basis. . 9 RS232 interface communication: real-time monitoring by computer or charging, discharging, or automatically after a battery charge and discharge activation data dump. Two), Product Features:?? Set charge, discharge, single detection, online monitoring and activation Observing the body, fully functional, a multi-purpose machine. ?? Smart three-stage charging, constant current discharge, real-time online polling each cell parameters. ?? Power devices using the new PTC ceramic resistor, safe, no red-hot phenomenon, long life. ?? Microcontroller U disk data dump to the application of technology to solve the problem of large-capacity data storage. ?? Charge / discharge end, U disk dump data via RS232 interface or by uploading a computer background can be automatically generated after processing a variety of charts, battery performance at a glance. ??
