Atnsinc 4pack Lm2596 DC-DC Buck Converter Adjustable Step Down Voltage Regulator 3-40v to 1.5-35v High Efficiency Power Supply Volt Reducer

The input voltage: DC 3 -40 V (Input voltage must be 1.5 V higher than the output voltage, no boost.) The output voltage: DC 1.5 – 35 V adjustable. The output current: It is recommended to use under 2A, maximum 3A(Additional heatsink is required). Steps: 1. Plugged into a power supply (3-40v), the power indicator light is lit, the module to work properly. 2. Adjust the blue potentiometer knob (generally booster clockwise, counterclockwise step-down) with a multimeter monitoring the output voltage to the voltage. Package includes:4XLM2596 DC-DC buck converter module(Note:The factory have tested these at max voltage so they are very high by default, takes about 15-20 turns CCW before the voltage starts ramping down)
