Description Description&Previewshipping&policyDescription: DC-DC step-down boost converter CC CV output 0.5-30V adjustable power module feature: -LCD display input/output voltage, output current/output power/output capacity/output time. -CNC adjustment can realize accurate and fast adjustment. It can step up and step down, the output voltage can be adjusted to 0.5-30V, and the current limit can be adjusted to 0-4A. -The reverse connection protection of the input terminal will not burn out when the connection is reversed. -Anti-backflow protection at the output. There is no need to add a backflow prevention diode when charging. -By default, the module can be set to ON/OFF. -Provide a variety of software protection mechanisms, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output will be automatically turned off. -The output ripple is very small, and the filter can be used. -Thick radiator. specification: Input voltage: 5.0-30V Output voltage: 0.5-30V -Output current: can work stably for a long time under 3A, and can reach 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 (it may fail when the module power is turned on under high power load) -Working frequency: 180KHZ -Hole distance for embedded installation: 78 x 39mm protection mechanism: -Input reverse connection -Prevent countercurrent output -Input undervoltage protection (4.8-30V adjustable, default 4.8V) -Output overvoltage protection (0.5-31V adjustable, default 31V) -Output over current protection (0-4.1A adjustable, default 4.1A) -Over power protection (0-50W adjustable, default 50W) -Overheating protection (80-110 adjustable, default 110) -Timeout protection (0-100h adjustable, default is off) -Overcapacity protection (0-60Ah adjustable, closed by default) How to use it? 1. Switch display parametes: In the normal interface, short press SW to switch the displayed content on the next line. Can switch current A, power W, capacity Ah and time h. Long press to change the content displayed at the top, switch between input voltage IN and output voltage OUT. 2. Set the output voltage value: In the normal interface, short press the U / I button to enter the voltage CC setting interface. A certain number of the set output voltage flashes. Rotate the encoder knob to increase or decrease the output voltage. Short press the knob to select the number to set the output voltage. After the setting is completed, short press the U / I button twice to return to the normal interface. Otherwise, it will automatically return to the normal interface without operating within 10s. 3. Set the constant current value (that is, the 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. It can be seen that a certain bit of the constant current value is blinking. Rotate the encoder knob to increase or decrease the value. Short press the encoder to select which bit of the 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 without operating within 10s. 4. By default, the module is set to on/off: 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 turned off by default when the power is turned on, and OPEN ON means that the output is turned on by default when the power is turned on. Press and hold the rotary encoder to switch between these two states. After setting, press and hold the U/I button to return to the normal interface. 5. Set the protection parameters to open and threshold: 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. LUP: Undervoltage protection threshold OUP: Overvoltage protection threshold OCP: Overcurrent protection threshold OPP: over power protection threshold OAP: Overcapacity protection threshold OHP: Overtime protection threshold OTP: Overheating protection threshold Short press the rotary encoder to select the number to set the protection parameter. Long press the encoder to set the protection parameters to "on" or "off" (Note: Only timeout protection and overcapacity protection can be set, and other protection parameters are on by default.). Rotate the encoder to change the parameter. After setting, press and hold the U/I button to return to the normal interface. 6. Voltage and current calibration: In the normal interface, press and hold the U / I button to enter the parameter setting interface. Short press the SW button until you enter Preview: Thank you for your purchase Problems? You can follow below process to chontact us.
