It adopts LCD 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;
- High-performance load:
It provides CC, CV, CR, CP as basic measurement mode
It provides professional battery test;
The Tran test mode can test the dynamic output performance of the power supply;
The scan test mode can test the continuity of power output within a certain range
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;
- Multiple safety protection:
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.
