Item Type: Converter Module Input Voltage: 5.0-30V Output Voltage: 0.5-30V Output Current: Works stably for a long time at 3A, up to 4A with enhanced heat dissipation Output Power: Natural heat dissipation 35W, enhanced heat dissipation 50W Voltage Display Resolution: 0.01V Current Display Resolution: 0.001A Conversion Efficiency: about 88% Soft Start: Yes (the module may fail when the high-power load is powered on) Working Frequency: 180KHZ Protection Mechanism: Reverse input, anti-backflow output Input Undervoltage Protection (4.8-30V adjustable, default 4.8V) Output Over-Voltage Protection (0.5-31V adjustable, default 31V) Output Overcurrent Protection (0-4.1A adjustable, default 4.1A) Over Power Protection (0-50W adjustable, default 50W) Over Temperature Protection (80-110 adjustable, default 110) Timeout Protection (0-100h adjustable, off by default) Over-Capacity protection (0-60Ah adjustable, off by default) How to Use: 1. Switch Display Parameters: In the normal interface, short press the SW key to switch the offline display content. Current A, power W, capacity Ah, and time h can be switched. Long press to change the height display content, switch between input voltage input and output voltage output. 2. Set the Output Voltage Value: In the normal interface, short press the U/I button to enter the voltage CC setting interface. A number of the set output voltage is flashing. Rotate the encoder knob to increase or decrease the output voltage. Short press the knob to select the output voltage number to be set. After setting, short press the U/I button twice to return to the normal interface. Otherwise, it will automatically return to the normal interface if no operation within 10 seconds. 3. Set the Constant Current Value (maximum output current allowed by the module): In the normal interface, short press the U/I button to enter the voltage constant current setting interface. Short press the U/I button again to switch to the constant current value. The constant current value of a certain digit is flickering. Turn the encoder knob to adjust the value. Short press the encoder to select the digit to be set. After setting, short press the U/I button to exit and return to the normal interface. Otherwise, it will automatically return if no operation within 10 seconds. 4. Default Output On/Off Setting: In the normal interface, press and hold the U/I button to enter the parameter setting interface. It displays OPEN OFF or OPEN ON. OPEN OFF means output is off by default when powered on. OPEN ON means output is on by default when powered on. Press and hold the encoder knob to switch between states. After setting, press and hold the U/I button to return to the normal interface. 5. Set Protection Parameters and Thresholds: In the normal interface, press and hold the U/I button to enter the parameter setting interface. Short press the SW button until the desired protection parameter appears. OUP: Overvoltage protection threshold OCP: Overcurrent protection threshold OPP: Overpower protection threshold OAP: Over-capacity protection threshold OHP: Overtime protection threshold OTP: Over temperature protection threshold
