CH6321X series program-controlled DC electronic load host adopts high-performance ARM processor with high-performance high-speed sampling AD; 4.3-inch TFT color screen supports Chinese and English interfaces, and it is easy to operate with well-designed guided menus. The display information is rich and comprehensive, and the load operation and fast charging voltage selection are displayed simultaneously; With a higher display resolution of 0.0001, it can more accurately monitor the voltage and current details of the tested product; USB HOST can conveniently use U disk to save data and upgrade firmware; Comprehensive comparator function with HANDLER interface makes batch test and systematic test of production line more secure; It has rich and comprehensive load functions: constant current CC, constant voltage CV, constant power CP, constant resistance CR, battery discharge test (real-time discharge curve can be displayed on the screen), dynamic test (dynamic output performance test of power supply), list test (performance test of power supply under various load conditions); The flexible software and hardware framework can meet the requirements of users' customized combined test functions, thus improving the test efficiency of production line; Intelligent fan control and excellent heat dissipation performance, combined with over-voltage, over-current, over-power, over-heat and reverse connection of voltage polarity and other perfect protection and alarm measures, make the instrument more reliable and safe; The whole instrument is equipped with RS232 interface as standard. With abundant SCPI instruction set, it can be easily connected to a computer for real-time data acquisition and instrument control. The electronic load with excellent performance can be widely used in the fields of production line test, product sophistication, laboratory test and research and development in power transformers, chargers, switching power supplies, various batteries and other industries.main feature4.3-inch TFT high-definition color screen display with optional Chinese and English operation interfaces.Add 900W power models, 600W/900W/1200W power options.The display resolution of current up to 0.0001 should be used for more testing occasions.500kHz high-speed sampling AD, real-time peak-to-peak measurement of voltage and current (Vpp/Vp+/Vp-/Ipp/Ip+/Ip-)CR-LED test mode and convenient parameter setting mode are more convenient to use.OCP test function, automatically obtain OCP protection point, peak power point (Pmax) and current voltage and current parameters.Up to 50kHz dynamic load frequency, settable current slope, voltage peak Vp+/Vp- real-time measurementTime measurement function, supporting OVP protection point and protection time test and power start-up time/hold time test.Battery test mode, which can test battery endurance and capacity, and has functions of internal resistance test and curve drawing.List test mode, which can test comprehensive parameters of power supply under various load conditions, including comparator function.U disk software upgrade function, always keep the latest operating version.One-click copying function makes it easy to save or transfer the screen display content, and USB HOST is standard for convenient data storage.One hundred sets of setting files inside the instrument and five hundred sets of setting files outside (U disk) can save and call setting parameters.Handler and RS232C interfaces as standard are convenient for online operation and signal output.Compatible with serial communication instructions from other mainstream manufacturers, and can be directly replaced.
