Features: Adopting LCD segment code screen with adjustable backlight. The operation process is simple and convenient, and with visual interface display system, it is easy to get started. Key lock function to prevent misoperation. It provides CC, CV, CR, CP basic measurement modes. It provides professional battery test. The Tran test mode can test the dynamic output performance of the power supply. The list test mode can simulate a variety of loading status changes. The short circuit test can be used to simulate load short circuit. Support external trigger input. Built-in buzzer alarm. Maintain data storage in case of power failure. Remote operation via USB, RS-232 (optional) or 485 (optional) interfaces. It provides overcurrent, overvoltage, overpower, over temperature protection. The overvoltage and overcurrent parameters can be set flexibly, so as to effectively protect the load. It has intelligent fan speed control function, which can effectively reduce the fan noise when it is working. With input polarity reverse prompt.
