20A 1200W Step-Up DC-DC 8-60V / 12-80V Voltage Buck Converter
High voltage DC - DC converter with high current, adjustable output voltage and high efficiency (> 95%). The DC converter works with the input voltage from 8V to 60V DC and has the ability to adjust the output voltage by the built-in potentiometer in the range from 12V to 80V.
This allows you to power any system with a higher voltage than you have. The system is great for powering all kinds of DIY circuits, electric bikes, power LEDs, devices with micro-controllers, Arduino modules, etc.
The converter has a large heat sink, but if the currents exceed 10A, active cooling should be used, so a fan that can be connected to a dedicated input on the "12VFAN" board. This output will provide with 12V for the fan automatically when the temperature or current increases.
The product has a STEP-UP characteristic, so with a lower input voltage it is possible to obtain a higher output voltage thanks to the "CV V-ADJ" potentiometer adjustment.
An additional advantage of the converter is the possibility of setting the maximum current in the entire operating range through another built-in "CC A-ADJ" potentiometer. Thanks to that the system will disconnect when the current value exceeds the set threshold.
Another built-in feature is the ability to set the minimum input voltage below which the inverter will disconnect. This protection is extremely useful while the system is powered by e.g. lithium batteries (Li-Ion / Li-Pol), accumulators or other cells - which cannot be discharged below a certain level.
