In order to better meet the development needs of charger testing, our company has developed a new generation of CH8716F (voltage 120V/current 30A power 3000W)/CH9716F (voltage 150V/current 30A/power 300W) charger tester after integrating the research and development experience of charger testing instruments for many years and comprehensive feedback from users. The series of instruments adopt high-performance ARM processor and have a Chinese-language interface. It provides user with humanized operation environment. Now it has been widely used in many large charger manufacturers.
The advantages over the previous generation are:
1.Full Chinese operation interface, make the operation more handy, simple and easy to use. 2. Higher measurement accuracy with high resolution of 0.1mV and 0.1mA
2.Flexible judgment conditions can be set to deal with various types of chargers (three-stage, constant power universal)
3.Data saving and calling functions (8716F 30 groups, 9716F 200 groups), each time the product under test is replaced, it is only convenient to call the internal stored data.
4.Standardized pedal switch start test to improve test efficiency. Normal testing of a product takes only 3-4 seconds
5.Excellent appearance design fresh and beautiful highlight grade
The following parameters of the charger can be obtained by one measurement sequence and can be distinguished according to the upper and lower limits.
1)Floating Charging Voltage 2) Turn-lamp Current
2)Maximum Protective Current 4) Maximum Charging Voltage
The instrument is tested by fully real simulation of the actual charging situation. When testing the switching lamp current, the current will automatically descend to find the switching lamp current point according to the set starting point and end point of the current. When testing the maximum current, the switching lamp current point can be automatically ascended by setting the starting point and end point of the current or the highest point of the current can be obtained by constant voltage mode. It only takes 3-4 seconds to complete the whole sequence test.
In the1, 2, 3, 4 steps of measurement, the discriminant results show that when one step is qualified, the buzzer whistles; when all four steps are qualified, the overall discriminant result "PASS" is given; as long as one step of measurement is not qualified, the overall discriminant result is "FAIL", and the buzzer whistles long.
Other test functions:
1. Constant Voltage CV, Constant Current CC, Constant Resistance CR, Constant Power CP, Short Circuit (SHORT), Basic Test Functions 2. Battery discharge function, which can test battery discharge time and total battery capacity 3. Mixed List Test Function, which can combine several basic test modes and judge the test results. 4. Dynamic test mode can switch current or voltage rapidly at least 1ms conversion time. Test the instantaneous output response ability of power supply
