YEDYLY Electrical Step-down Module High-power Self-protection Adapter Adjustable

Features: Self-protection features include: Thermal shutdown and Current-Limit protection. The Voltmeter Resolution: ±0.1V 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.
