Boost Step Up module has the function of delivering a constant output voltage higher than the input voltage against variations in input or load voltage. 
It supports output currents up to 6A, input voltage between 10V to 32V and output voltage between 12V to 35V. The output voltage is selected by a multi-turn potentiometer.
The Boost Step Up 6A 150W voltage lift makes it possible to obtain a regulated voltage from a source with a lower voltage, for example: to obtain 24V from a 12V battery. 
It is capable of handling a load of up to 6A or 150W max.
