ET5411A+ Programmable Single Channel DC Electronic Load 500V 15A 400W Single Channel DC Programmable Electronic Load Tester CC CV CR CP CC+CV CR+CV Mode 2.8inch TFT LCD Screen The DC programmable electronic load is equipped with a 2.8-inch LCD screen, which is convenient and simple to operate, stable in operation, and superior in performance. Equipped with 12 common modes and complete test functions, and the test resolution can reach 1mV/1mA. It can be widely used in the production test of chargers, switching power supplies, linear power supplies, batteries and other industries. Features: It provide CC, CV, CR, CP, and CC+CV, CR+CV several basic measurement modes. Adopt 2.8-inch TFT LCD screen, display rich content, support Chinese and English display. The operation process is simple and convenient, and with the intuitive interface display system, it is easy to get started. With key lock function to prevent misoperation. Provide battery internal resistance test; provide software remote compensation function. Provide professional battery testing and LED testing. Dynamic test mode can test the dynamic output performance of the power supply. Scanning test mode can test the power output continuity within a certain range. The list mode can simulate a variety of load status changes. Short circuit test can be used to simulate load short circuit. Support external trigger input (DB9 interface is required). Built-in buzzer alarm. Power-off data storage function. With overvoltage, overcurrent and overpower conservation functions, overvoltage and overcurrent parameters can be flexibly set to effectively protect the load. It has secondary over-temperature conservation function to realize double over-temperature conservation of software and hardware. With intelligent fan speed control function, it can effectively reduce fan noise during work. With output polarity reverse conservation.
