Tutorial:

Input Method: Vin Input Positive Stage, GND Input Negative Pole

Output Mode: Vout Output Positive Stage, GND Output Negative Pole

Maximum Output Current: Maximum Output Current = 3/(Input Voltage-Output Voltage)

Input Voltage: 4. 5v-40v (the Maximum Measured Limit in Our Store Can Reach 40V),

Adjustment Method: First Correctly Connect the Input Power Supply (between 4.5 and V-40V), Then Use a Multimeter to Monitor the Output Voltage and Adjust the Potentiometer (Generally, Turn the Voltage to Boost, Turn the Voltage to Buck)

Tips: When Adjusting the Voltage, Please Adjust the Required Voltage When the Load Is Not Added.

Statement: the Output Power of This Module Is Affected by Various Factors Such as the Front-Level Power Supply and the Rear-Level Load in Addition to the Carrying Capacity of the Module Itself; the following Data Are Measured by Professional Equipment, other Factors Are Not Considered.

The Power Module Is a Kind of Electronic Components. Please Consider Buying It without the Information of Electronic Professionals.
