I. Product Overview 
 HDGC3960 DC power supply tester is based on the country on the power system with battery DC power plant operation and maintenance of technical regulations "relevant requirements can be realized on the inspection and testing of different capacity charger and battery capacity, and accurate and reliable test substation DC power system regulation accuracy, the accuracy of the steady flow, the ripple coefficient and other parameters. 


 Second, the function 
 ? Comprehensive test functions: test DC current measurement, the measurement of DC voltage, AC voltage measurement and the measurement of ripple voltage regulation accuracy and calculate the accuracy of the steady flow regulator ripple coefficient and the steady flow ripple factor. 
 ? Regulator precision measurement capabilities: AC input voltage ± 10% range of changes in the rated voltage, load current in the 0 to 100% of rating changes, the DC output voltage is within the adjustment range of any number of its regulator accuracy. 
 ? Steady flow accuracy measurement: ± 10% range of changes in the rated voltage, output current value of 20% to 100% rating, charging voltage of the AC input voltage changes within the adjustment range of the specified steady flow accuracy. 
 ? Ripple precision measurement functions: DC voltage charging device output, the fluctuating values ??of peaks and valleys of the poor half of the average DC output voltage, calculate the regulator ripple coefficient and the steady flow ripple coefficient. 
 ? Battery discharge function: digital control constant current discharge, automatic real-time monitoring of single cell and battery voltage, battery discharge measure DC current, and measuring DC voltage and discharge time, and calculate the discharge capacity. 
 ? To monitor the discharge of the functions: real-time through wireless communications, monitoring, recording a single section or the whole battery voltage, and real-time curve and histogram display on a PC. 
 ? Automatic protection function: by setting the minimum protection voltage of the battery pack and single cells, the discharge capacity, discharge time four door alarm and automatic protection. 
 ? Data analysis capabilities: via the PC software, the measurement data system analysis. 

 Third, the product features 
 ? Using large-screen LCD display, Chinese interface, touch-operated, easy to use. 
 ? Automatic test: only in accordance with the technical specifications of the charger to set test parameters, the device can be fully automated to complete the adjustment of the AC voltage, a load resistor, the parametric test, automatically record test values ??and to stop testing. 
 ? Automatic on-line real-time detection, record a single section or the whole battery voltage. 
 ? Automatic test protection function: When in the testing process, testing to the entire group or single cells are abnormal, the automatic termination of the test, to prevent excessive discharge the battery completely avoid the impact of the equipment; artificially terminate is required carry out the testing process. 
 ? Data into the computer can be a storage management, preservation and analysis of long-term historical data.
