This XL4016E1 200W Step Down Power Supply Module with voltage rating 4-40VDC to 1.25-36VDC.This module is rated for a maximum power of 200W. The output current for the module can be increased to 8A with the addition of an external fan onto the heatsinks to cool the IC. Note: This Product is available in two different variants (XL4016E1 and HW-674) with the same working, we will ship it randomly. Features Adjustment method: first correct input power (between 4-40V) then multimeter to monitor the output voltage and adjust potentiometer (usually clockwise turn boost, buck turn counterclockwise), Input: IN input positive IN- input negative Output: OUT output positive OUT- output negative Static power consumption is only about 6mA. Connection: Welding, plus pin can be directly soldered after the PCB. Short circuit protection: current limiting, thermal protection, self-recovery. Non-isolated step-down (BUCK) switching regulator. Short circuit protection: Current limiting, self-recovery Potentiometer adjustment direction is as Clockwise (increase) and Anti-clockwise (decrease) Non-synchronous rectification
