1、[Accurate Encoder Control] The encoder knob of this DC power supply allows for accurate voltage or current settings. Simply press the knob and rotate to set your desired value within 0 to 9. It features storage memory with 3 sets of memory functions and multiple storage. 2、[Convenient Output Button] Press to easily turn on or off output. Check the working status through indicator lights on the display screen. Adjust voltage and current data anytime when the output is off, preventing damage to load devices due to forgetting to turn off the output. 3、[Multiple Preservation] The power supply automatically stops output and emits a warning beep in case of short circuits during operation, guarding both the power supply and load devices. Also includes safety features such as overvoltage, overcurrent, over temperature, and overload preservation. 4、[Automatic CC CV Switching] The adjustable power supply can automatically switch between constant voltage and constant current modes based on load changes. The CV indicator light is on for constant voltage, while the CC indicator light is on for constant current. 5、[Smart Temperature Controlled Fan] When the internal temperature of the power supply reaches a specified level, the fan automatically starts cooling. Widely applicable for laboratories, production lines, and appliance repairs, offering versatility for various settings.
