· Input voltage range : 3-35V DC 

· Output voltage range : 3.5-35v DC

· Efficiency : 96.7%(max) 

· Output current : 6A(max)

· Voltmeter range:4 to 40V,error +-0.1v

· L * W * H = 6.7 x 4.3 x1.2 cm(approx.) 

· When adjust the blue potentiometer ,please use a multimeter to monitor the voltage 

· Rotating Clockwise can rise the voltage while rotating  counterclockwise could lower the voltage 

· When the module output voltage can not be adjusted ( the output voltage is always equal to the input voltage ) Please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.
