LM2596HVS/LM2596/LM2596S Power Module + LED Voltmeter DC-DC Adjustable Step-down Power Supply Module with Digital Display 3A

LM2596 DC-DC Buck 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 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.
