Universal DC-DC converter 3A 35W

The step up/step down converter system is a universal power supply device. The input voltage from the converter's operating range is converted into the set output voltage. The biggest advantage of such a system is that it can both lower and increase the supply voltage.

We can therefore use it in many applications where we need a constant voltage, regardless of changes in the supply voltage.

An example would be the application of a battery with a nominal voltage of 14.8V (4s liIon pack), when charged it reaches 16.8V, and when discharged it reaches 12V. In the application we need a voltage of 15V, so from the range of 16.8 to 15V the converter lowers the voltage, and in the range from 15V to 12V it increases the voltage. Thanks to this, regardless of the battery charge state, the voltage in the system is constant and amounts to 15V.

The converter is a CC/CV module, which means that we can adjust the current and voltage at the converter output. This functionality allows this module to be used as a battery charger. To properly configure the converter, set the output voltage using a potentiometer. Then load the converter output with a current meter and set the desired maximum output current value. ATTENTION - prolonged loading of the meter may damage it.

The converter module can also be used as a high-power LED driver.
