Instrument introduction: The DPS3806 DC-DC CNC buck-boost module is a digitally-displayed CNC buck-boost module with small size, high power, high efficiency and stable work. The characteristic of this module is that when the input voltage is lower than, higher than, and equal to the output voltage, the output voltage can remain stable and unchanged, and the precision measurement calculation of the high-speed microcontroller is added, which can accurately adjust the output voltage and current. 10 groups of storage locations, parameters can be stored and recalled at any time, which is convenient to use. Equipped with a four-digit eight-segment LED digital tube, which can display voltage, current, power, capacity and other parameters in real time. At the same time, the machine has functions such as automatic output after power-on, automatic wheel display of parameters, etc., which can be turned on or off according to the needs of use. Instrument characteristics: 1. The use of advanced microprocessors can accurately adjust the output voltage and current; 2. With memory saving function, 10 groups of parameters can be stored, and can be stored and recalled freely; 3. Full digital display, convenient and easy to use; 4. With constant voltage and constant current status; 5. Using 4-digit high-brightness digital tube, it can display output voltage, current, power, capacity and other parameters in real time; 6. Automatic/manual switching to display parameters such as voltage, current, power, capacity, etc.; 7. With output OUT, constant voltage CV, constant current CC indicator light, you can check the working status in real time; 8. It can be set whether to output automatically after power-on; 9. You can save the current set voltage and current value with one key. Material: PCB colour: green Package Contents: 1 x Constant Current Power Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
