Power Supply Module DC-DC 5V To 3.5V/9V/12V LCD USB Step UP/ Down Desktop Adjustable Boost Buck Converter Voltmeter Out 1.2V-24V

Power Supply Module DC-DC 5V  is a DC adjustable step-up/down power supply module with an LED digital tube display. Display output voltage and output current. Adjustable output voltage. Set output voltage to meet the requirements. Simple and efficient, practical.

Power Supply Module Specification:

• Input Voltage for Pads: DC 3.5V-12.0V
• Input Voltage for USB: DC 5.0V
• Output Voltage: DC 1.2V-24.0V
• Output Power: 3W(Max)
• Conversion efficiency: 95%
• Working Temperature Range: -20℃~85℃
• Working Humidity Range: 0%-95%RH

Power Supply Module Features:

• 3-Bit digital tube display
• Three input power modes
• High resolution
• Multiple parameters can be displayed in turn
• Low power supply
• Support power-saving mode
• Support enable output mode

Button/Potentiometer/LED Introduction:

• Long press means need to keep press for more than 3second.
• Button ON: Short press to turn ON or OFF output voltage. Long press is used to turn ON or OFF screen meanwhile voltage keep output.
• Button SW: Short press to switch display output voltage, output current or display these parameters in turn. Long press is used to enter or exit calibration mode.
• 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.
• V LED: Red indicator. It will turn ON when displaying output voltage.
• A LED: Blue indicator. It will turn ON when displaying output current.
• 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 3.5V-12.0V.
  • It can only choose one input method.
• Output terminal:KF-301-2P 5.08mm blue terminal. It can output DC 1.2V-24.0V.

Using Steps:

• Connect right input voltage at input terminal;
• Adjust CV constant voltage potentiometer to set output voltage according to require. Rotate CV potentiometer counterclockwise for more than 10 turns if the output voltage can not be adjusted.
• Remove the input power supply and then connect the load at the output.
• Re-connect input power supply to use the module.
• The output current can not keep a fixed value output. It changes with load. But output power can not exceed 3W.

Application:

• Ordinary power supply
• Instrument voltage display
• Test meter
• Circuit test
• Power conversion

Note:

• It is a DC power module, So it can not connect to AC power.
• Please don’t short output.
• ’IN-’ and ‘OUT-’ can not be connected together, otherwise the module can not support constant current output.
• Please make sure input power is more than load power.
• Please step down output power if the module is hot.
• Rotate CV potentiometer counterclockwise for more than 10 turns if the output voltage can not be adjusted.
• The output current can not keep a fixed value output. It changes with load. But output power can not exceed 3W.
• Please read the user manual and description before use.
