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. Can be set to Z high current, which is convenient for charging the battery and other applications. Using iron-silicon-aluminum core inductor, high efficiency and low heat generation, boosting efficiency reaches 90%, step-down efficiency is 88%, Z large input and output current is 5A, large heat sink, with shell and cover.
Characteristic parameters:
1. Input voltage: DC 6 - 35V
2. Output voltage: DC 1.0 - 33V (Note: This board is an automatic step up and step down board, the output voltage can be greater than the input voltage or 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)
6. Z large input current: 7A (please leave a certain margin for continuous operation for a long time)
7. Z large output current: 5A (please leave a certain margin for continuous operation for a long time)
8. Module size: 70x39x32 mm (length x width x height)
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 Z large output current value, the current value displayed on the multimeter is the constant current value. After the completion, connect the load is working normally.
Package includes:
1 x Constant Current Automatic Voltage Regulator
