CH9720 Programmable DC Electronic Load Instructions Chapter II Overview
Chapter II Overview
The main contents of this chapter: basic product parameters and function introduction,
front and rear panel introduction and LCD display summary, and basic operation methods.
2.1 Product Introduction
CH9720X series electronic load is the new generation high performance
multi-function DC electronic load based on the professional accumulation in the field of
electronic load and wide users. The high performance ARM processor with high speed
sampling AD is adopted, so it can simulate the load feature of different power supply.
4.3 inch TFT display supports Chinese&English operation, matched with guided menu,
make the operation easier. The displayed information is rich and direct. With the
resolution of 0.0001, the voltage and current details can be monitored more
accurate.USBHOST(available for 9720BU/9720CU) can be used to save data,also for
firmware update. The comparator function with HANDLER interface can ensure the
batch test and systemization test. The load function is rich: CC, CV, CP, CR,
CR-LED(Simulate the characteristic of driver),battery discharge function(Display the
real-time discharge curve), transient test(Test the dynamic output performance of power
supply) , list test(Test the performance of the power supply under different condition).
The flexible soft and hard frame can meet the demand of group test so that to improve
the test efficiency. The smart fan control and excellent dispersion performance with the
protection alarm steps like over voltage, over current, over power, over heat and reverse
voltage polarity can make the instrument more reliable and safer. It is easier to connect
with computer for real time sampling collection and control with SCPI.
The electronic load can be widely applied for the production line of power transformer,
charger, switch power and battery, and the research field like lab.
