DollaTek Small DC Buck Voltage Converter Step Down Voltage Regulator Module Board 4-38V to 1.25-36V 5V/12V Adjustable Output Voltage Stabilizer Transformer

• With power supply green LED indicator and the mini voltmeter which can be calibrated by adjusting potentiometer
• High power of 5A and low ripple; has heatsink and copper pillar; Over-heating/short-circuit protection allows safe usage
• Press the switch button to choose testing input/output voltage; "IN"LED light when testing input voltage; "OUT" LED light when testing output voltage
• Press the left-side button to turn ON/OFF voltmeter; Wiring terminals makes convenient usage even without soldering iron
• Adjust the potentiometer in clockwise direction for output voltage increase and decreasing output voltage in counter-clockwise direction
