1.1 LCD can display input/output voltage, output current/output power/output capacity/output time; 1.2. CNC adjustment, accurate and fast, can boost and lower voltage, output voltage can be adjusted at will from 0.5-30v, limit current 0-4a can be adjusted at will; 1.3. Anti-reverse connection protection of input end, which will not burn out; 1.4. Anti-reverse irrigation at the output end, no additional anti-reverse irrigation diode is needed to charge the battery; 1.5. The module can be set to open/close by default; 1.6. Multiple software protection mechanisms are available, and the protection threshold is adjustable.When the working parameters of the module exceed the protection threshold, the output will be automatically closed. 1.6. Output ripple is small and PI filter is available; 1.8. Thicken radiator fins. Soft start: yes (with high power and load module may fail when starting) Protection mechanism: Input anti-reverse connection; Output anti-reverse irrigation; Input undervoltage protection (4.8-30v adjustable, default 4.8v) Output overvoltage protection (0.5-31v adjustable, default 31V) Output overcurrent protection 0-4.1a (adjustable, default 4.1a) Overpower protection (0-50w adjustable, default 50W) Overtemperature protection (80-110 adjustable, default 110℃) Timeout protection (0-100h adjustable, off by default) Super capacity protection (0-60ah adjustable, off by default) Operating frequency: 180KHZ Dimensions: length * width * height 79mm*43mm*26mm Weight: 92g (including package) 2. Product parameters Input voltage: 5.0-30v Output voltage: 0.5-30v Output current: can work stably at 3A for a long time, and can reach 4A under enhanced heat dissipation Output power: natural heat dissipation 35W, strengthen heat dissipation 50W Voltage display resolution: 0.01V Current display resolution: 0.001A Conversion efficiency: about 88% ℃ Method of use 5.1. Switch display parameters -- in the normal interface, press SW to switch the display below the display screen, and switch the display content between current A power W capacity Ah time h.Long press SW button to switch the uplink display on the display screen and switch the display content between input voltage IN output voltage OUT. 5.2. Set output voltage -- press U/I button in the normal interface to enter the interface of setting voltage constant current.It can be seen that a certain digit of the output voltage value is flashing. Rotate the encoder left and right to adjust the major and minor.Short press the rotary encoder to choose which bit of output voltage to set.After setting, press U/I button 2 times to return to the normal interface.Or automatically return to the normal interface after stopping operation for 10s. 5.3. Set constant current value (that is, the maximum current value allowed to output by the module) -- press U/I button in the normal interface to enter the setting voltage constant current interface.Then press U/I button and switch to setting
