Adjust and maintain stable output voltage over a range of input voltages using digital controls. Useful for a wide range of applications, such as powering 5V USB devices and low voltage electronics from a 12V battery, and many other electronic projects. Constant voltage regulation, suitable for LED strips and modules, but not for raw LEDs. Use buttons to adjust the output voltage with 0.1V precision. Input Voltage: 5-36V DC, Output Voltage: 1.25-32V DC, Max Load: 75W/5A Peak, 50W/3.5A Sustained (whichever is lower, amps or watts) Conversion Efficiency: Up to 96%, Dimensions: 66x39x18mm, XL4015 IC, 180KHz Switching Frequency Input must be at least 1.5V more than the output voltage. Applying reverse polarity voltage to the input or output may damage the module. This module does not come with a heatsink for the IC. Moderate to high sustatined loads may require additional cooling.
