Вопросы:
What is the maximum output current of this buck converter module?
The maximum output current is 8A, but it is recommended to use a cooling fan if the power tube's temperature exceeds 65°C.
Does this module have input reverse polarity protection?
No, this module does not have input reverse polarity protection, so ensure correct polarity when connecting.
What are the typical applications for this DC DC step-down converter?
This module is ideal for high-power LED drivers, lithium battery charging, vehicle-mounted power supplies, and low-voltage system power supplies.
How do I adjust the output voltage and current?
Use the 3296 multiturn potentiometers; the one near the input adjusts voltage (CV), and the one near the output adjusts current (CC).
