Multifunctional, constant voltage, voltage stabilization, voltage rise and fall DC-DC voltage regulator power module, with a large input voltage range supporting 5.5V-35V Good material, high stability, and high cost-effectiveness Easy to use and operate Application scenarios can be applied to smart home, industrial internet of things, vehicle power and other scenarios Module name: Output positive and negative pole voltage rise and fall power module Power supply range: DC5.5V-DC35V (step-down module, input needs to be about 2V higher than output) Output range: DC1.22-16V adjustable, increasing clockwise and decreasing counterclockwise. Output current: positive terminal 3A (Max) and negative terminal 2A (Max). As the output voltage increases, the output current decrease. When outputting 16, the positive terminal is about 1A and the negative terminal is about 0.7A. Product size: approximately 57mm x 42mm x 16mm Note:due to different production batches, the printed characters are different, which does not affect the use.
