A powerful non-isolated step-up converter allows increasing voltage from 6 to 35V to an adjustable 31.8–66V (output voltage will be the same or higher compared to the input voltage). It provides a continuous output current of up to 7A. With an efficiency of up to 97.6%, it minimizes energy loss and ensures efficient operation. The compact dimensions of 70 × 39 × 31 mm, including passive cooling, allow easy integration into various DIY applications. Professional installation is required. Before connecting, turn the trimmer to the maximum; do not decrease it to the minimum, as it may damage the converter.
