◆ During the test process, the test data is displayed in real time, and all the charts are clear and beautiful, intuitive and convenient.
◆ Can save, echo testing data or upload it to PC, dedicated DC power supply integrated tester data analysis software for detailed data chart analysis. Test at any time, save, edit, print at any time.
◆ Data is transferred to the computer for warehousing management, which can be saved and analyzed for long-term historical data.
◆ Reasonable design with Modular structure of small size & light weight. For reliable operation,
◆ Mass memory: store 300 Strings of data for voltage regulation accuracy test, ripple coefficient test, steady current accuracy test, efficiency test, and current limit characteristic test.
◆ Complete communication function, with RS485 communication interface and USB interface, the use of U disk to transmit data, you can update the tester software on the U disk.
◆ With automatic test protection function: When in the test process, the whole String or single battery abnormality is detected, the test is automatically terminated.
◆ Prevent over-discharge on the battery, completely avoid impact on the equipment, and can also artificially terminate the ongoing test process as needed.
DFT-8801 Features:
◆ Comprehensive test: The comprehensive test shows the testing of DC current, the testing of DC voltage, the testing of AC voltage and the testing of ripple voltage, and calculates the voltage regulation accuracy, current stability accuracy, voltage regulation ripple coefficient and steady flow ripple coefficient.
◆ Voltage regulation accuracy testing: the AC input voltage changes within 10% of the rated voltage ±, the load current changes from 0 to 100% of the rated value, and the DC output voltage is regulated at any value within the adjustment range.
◆ Steady current accuracy testing: any value of the AC input voltage changes within the rated voltage ±10%; the output current is 20% to 100% of the rated value, and the charging voltage changes within the specified adjustment range.
◆ Ripple accuracy testing: In the DC voltage output of the charging device, half of the difference between the peak of the pulsation amount and the valley value, and the ratio of the average value of the DC output voltage, the stable voltage ripple coefficient and the steady flow ripple coefficient are calculated.
◆ Efficiency testing: the ratio of the AC rated input power of the charging device to the DC output power, the efficiency testing shows the testing of AC voltage, testing of AC current, testing of DC voltage, testing of DC current, and calculation of input power, output power and efficiency.
◆ Harmonic testing: Current harmonic testing, mainly showing the condition of 1 to 25th harmonics, including the number of harmonics (or fundamentals), the true RMS value of harmonics, the harmonic containment rate (HR), the total harmonic distortion rate (THD) and other parameters.
◆ Powerful data processing function: It can curve display a number of testing results of the battery, generate reports, and perform comprehensive calculation and analysis to accurately identify.
◆ Data analysis: Including comprehensive analysis, voltage regulation accuracy analysis, steady current accuracy analysis, ripple coefficient analysis, efficiency analysis, grid harmonic analysis and battery discharge analysis, the content of the original testing interface can be redisplayed.
◆ Data Upload: This feature allows users to upload saved testing data to a computer for various analyses.
◆ System Upgrade: This feature allows users to update the meter software using a U-disk.
