S9 L3+ power boost module 14v L3+ green DC to DC step-up module is used to repair and replace the faulty boost area of the L3+ s9 miner hash board. Input voltage 3.7V-12V, output voltage 14.2V max.

Precautions

1. The input voltage cannot exceed the maximum input voltage

2. Peak current output current does not exceed 2A

Tip: Reverse the potentiometer 15 times before testing! The potentiometer on the chest counterclockwise increases the facing voltage! Some customers report that the output voltage of the module cannot be adjusted and is always equal to the input voltage. In case of such problems, turn the potentiometer counterclockwise for more than 10 turns, and the module can be used to adjust the voltage normally.
