LM2596 3A Buck Step Down Power Converter LED Digital Voltmeter Display Adjustable Board 3A Short Circuit Protection

LM2596 LM2596S power module + LED Voltmeter DC-DC adjustable step-down power supply module with digital display

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 boost,counter-clockwise rotationTurn down) and reach with a multimeter to monitor the output voltage required voltage.Note:Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat 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.
