이 제품을 사용하려면 테스터기는 필수로 있어야 함

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.
