In = 7V-35V / Out = 1.25V-30V(Adjustable) @ 3A - Switching Regulator
This is an LM2596 DC-DC buck converter step-down power module with high-precision potentiometer for adjusting output voltage, capable of driving a load up to 3A with high efficiency. When the output current required is greater than 2.5A(10W) an external heatsink is suggested.
