3A Adjustable LM2596S dc step-down Buck Voltage Converter Regulator module

Features:
1. The range of input voltage: 3.2 V to 40 V dc (input voltage must be higher than to the output voltage of 1.5 V above. Can’t booster)
2. The range of output voltage: 1.25 V dc to 35 V voltage adjustable, high efficiency (92%) largest maximum output current is 3A.

Instructions:
1. Power (3-40V), power indicator light, the module is working properly.
2. Adjust the blue potentiometer knob (clockwise rotation generally boosts, counter-clockwise rotation Turn down) and reach with a millimeter to monitor the output voltage required voltage.
Note:
Current work long hours is recommended for use in less than 2.5A, while adding bulk Heat sink (10W output above),because it is the step-down module, in order to ensure stable output Set, please keep the minimum 1.5V differential.
