The Voltmeter Digital Display Range: 0v- 45v
Input Voltage Range: Dc 4v-40v (Do not exceed input voltage, this will damage the converter.)
Output Voltage: Continuous Adjustable (1.3v-35 V)
Output Current Max: 2A
Size :56*35*15 mm
Press the key "S1" switch on/off the display
Press the key "S2" to let the display show the input or output voltage. when the first led light, it shows input , the second led shows output .
You can regulate the output voltage with the regulator (see the picture) witch is a adjustable resistor. You need small flat screwdriver.
Note:
To guarantee the accuracy of the voltmeter , make sure the input voltage above 4V.
The input voltage must be 1.5v higher than the output voltage or 1.5v above.
The step down converter we'll be put in regulation mode, so before turning the regulator check what is the output voltage
