Introduction
The high-power automatic step-up and step-down module with constant current function can boost or step down, the input voltage can be higher or lower than the output voltage, and the output voltage remains unchanged. The automatic voltage regulation function has a constant current function. The maximum current can be set to facilitate the application of charging the battery. Using iron-silicon-aluminum core inductor, high efficiency and low heat generation, boosting efficiency reaches 90%, step-down efficiency is 88%, maximum input and output current is 5A, large heat sink, with shell and cover.
Characteristic parameters
1. Input voltage:DC 6 ~ 35V Do not reverse the positive and negative poles, or directly damage
2. Output voltage:DC 1.0 ~ 35V (Note:This board is an automatic lifting plate, the output voltage can be greater than the input voltage can also be less than the input voltage)
3. Constant current adjustment range:0.05A ~ 5A
4. Conversion efficiency:90% (measured when inputting 12V output 19V/2.5A, efficiency is related to input voltage and output voltage and current)
5. Maximum input current:7A (please leave a certain margin for continuous operation for a long time)
6. Maximum output current:5A (please leave a certain margin for continuous operation for a long time)
7. Module size:70x39x32 mm (length x width x height)
8. When the input voltage is lower than 6V, the input needs to be disconnected, and the output will be reconnected.
Note:The power module works definitely will generate heat. The natural heat dissipation power of this module is about 60W. If the heat dissipation conditions such as adding a fan are good, it can work more than 100W. In the case of a constant current and a large current, there is a sound from the inductor, which is a normal phenomenon.
Module instructions
Connect the power supply, the module works normally and outputs the voltage. Connect the output terminal with the multimeter voltage. Turn the voltage adjustment potentiometer to adjust the output voltage to the desired value. Then adjust the multimeter to 10A current file, the positive pen is connected to the positive output, and the negative pen is connected to the negative output. And adjust the constant current set potentiometer to your desired maximum output current value, the current value displayed on the multimeter is the constant current value. After the completion, the load is working normally.
Package includes
