DC 5V to 15W 1V~24V 12V USB Adjustable Step Up Down Voltage Power Supply Module

Description: It is a DC adjustable constant voltage constant current step up/down power supply module with LED digital tube display.Display output voltage, output current and output power.Adjustable output voltage and current.Set output current to meet the require.It can be used as ordinary buck power supply module, charger and LED constant current driver.Simple and efficient, practical. Features: Support short circuit protection/anti-backflow protection/constant voltage constant current adjust;4-Bit digital tube display;4-Bit digital tube display;Three input power modes;Support over-current protection/over-current protection/over-voltage protection/over power protection/over temperature protection/charging mode;High resolution;Multiple parameters can be displayed in turn Parameters: Product Name:USB 2A Step Up/Down Power Supply Module Input Voltage for Pads:DC 4.0V-13.0V Input Voltage for USB:DC 5.0V Output Voltage:DC 0.5V-30.0V Output Current:2A Output Power:15W(Max) Voltage Display Precision:+/-0.1V Voltage Display Resolution:0.1V Current Display Range:0~2.2A Current Display Precision:+/-0.05A Voltage Display Resolution:0.001A Power Display Range:0~99.99Ah Capacity Precision:0.00W~15.0W Protection Temperature Threshold:100℃ Conversion efficiency:95% Working current:30mA Working Temperature range:-20℃~85℃ Working Humidity Range:0%-95%RH Button/Potentiometer/LED introduction: 1.Long press means need keep press for more than 3second. 2.Left Button:Long press is used to set default ON or OFF for next re-power at display mode or as ‘Minus -’ in calibration mode.Short press to select whether output voltage at display mode. 3.Right Button:Long press is used to enter or exit calibration setup mode at display mode or as ‘Plus +’ in calibration mode.Short press to switch display output voltage,output current, output power or display these parameters in turn. 4.CV Potentiometer:Adjust output voltage.Increase the output voltage when rotating clockwise.Please rotate the CV potentiometer 10 turns in counterclockwise if the output voltage cannot be adjusted. 5.CC Potentiometer:Adjust output current.Increase the output current when rotating clockwise.Note:It is not keeping a fixed output current.When the load current reaches the set current value, the module starts to fix output this current value. 6.ON LED:Green Output indicator.It will turn ON when there is a output at output terminal.Otherwise it is OFF. 7.CC LED:Red Constant current output indicator.It enters the constant current state when the load current reaches the set current and CC constant current indicator turns ON. Input terminal:There are three input methods: Method 1:Standard Type A USB Male .It just can input DC 5V. .Method 2:Micro USB Female.It just can input DC 5V. Method 3:IN+ and IN- pads.It can input DC 4.0V-13.0V. It can only choose one input method. Output terminal: KF-301-2P 5.08mm blue terminal. It can output DC 0.5V-30.0V. Protective function: Over-Voltage Protection:Module will turn OFF output voltage automatically if output voltage is more then 30.5V. Over-Current Protection:Module will turn OFF output automatically if output current is more then 2A. Over-Power Protection:Module will turn OFF output automatically if output power is more then 15W.It will display ‘-OP-’.User need reduce load power and then press ‘ON/OFF’ button. Current error:Large display error when output current is less than 0.05A.It can not display output current if current is 10~40mA. Over Temperature Protection:Module will turn OFF output automatically if termperature is more then 100℃.It will display ‘-OT-’.User need reduce load power and then press ‘ON/OFF’ button. Note: 1.It is a DC power module,So it can not connect to AC power. 2.Please don’t short output. 3.’IN-’ and ‘OUT-’ Package Included: 1PCS*DC 5V to 1V 12V 24V 15W USB Adjustable Step Up Down Voltage Power Supply Module
