Item Type: Converter Module_x000D_ Input Voltage: 5.0-30V_x000D_ Output Voltage: 0.5-30V_x000D_ Output Current: Work stably for a long time at 3A, up to 4A with enhanced heat dissipation_x000D_ Output Power: Natural heat dissipation 35W, enhanced heat dissipation 50W_x000D_ Voltage Display Resolution: 0.01V_x000D_ Current Display Resolution: 0.001A_x000D_ Conversion Efficiency: about 88%_x000D_ Soft Start: Yes (the module may fail when the high-power load is powered on)_x000D_ Working Frequency: 180KHZ_x000D_ Protection Mechanism: Reverse input, anti-backflow output_x000D_ Input Undervoltage Protection (4.8-30V adjustable, default 4.8V)_x000D_ Output Over-Voltage Protection (0.5-31V adjustable, default 31V)_x000D_ Output Overcurrent Protection (0-4.1A adjustable, default 4.1A)_x000D_ Over Power Protection (0-50W adjustable, default 50W)_x000D_ Over Temperature Protection (80-110-adjustable, default 110)_x000D_ Timeout Protection (0-100h adjustable,off by default)_x000D_ Over-Capacity protection (0-60Ah adjustable, off by default)_x000D_ _x000D_ How to Use:_x000D_ 1. Switch Display Parameters:_x000D_ 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 can change the height display content, switch between input voltage input and output voltage output._x000D_ 2. Set the Output Voltage Value:_x000D_ 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 and will not operate within 10s._x000D_ 3. Set the Constant Current Value (that is, the maximum output current allowed by the module):_x000D_ 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 value. It can be seen that the constant current value of a certain bit is flickering. Turn the encoder knob to increase or decrease the value. Short press the encoder to select the number of constant current value to be set. After the setting is completed, short press the U/I button to exit the setting interface and return to the normal interface. Otherwise, it will automatically return to the normal interface and will not operate within 10s._x000D_ 4. By Default, the module is Set to on/off:_x000D_ 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 that the output is shut down by default when the machine is turned on, and OPEN on means that the output is turned on by default when the machine is turned on. Press and hold the spin encoder to switch between these two states. After setting, press and hold the U/I button to return to the normal interface._x000D_ 5. Set the Protection Parameter on and Threshold:_x000D_ In the normal interface, press and hold the U/I button to enter the parameter setting interface. Short press the SW button until the protection parameter to be set appears._x000D_ OUP: Overvoltage protection threshold_x000D_ OCP: Overcurrent protection threshold_x000D_ OPP: Overpower protection threshold_x000D_ OAP: Over-capacity protection threshold_x000D_ OHP: Overtime protection threshold_x000D_ OTP: Over temperature protection threshold 1The structure of this product provides a variety of software protection mechanisms that are safer, more reliable and practical. 2This converter has a large heat dissipation area and can better maintain long‑term operation. 3The input terminal of this converter module has anti‑reverse protection, which will not bu
