Important Notes
-
The input voltage must be higher than the required output voltage.
-
For continuous operation near 3A, additional cooling may be required.
-
The module reduces DC voltage; it cannot increase voltage.
-
Confirm the potentiometer functions and terminal markings on the actual module before connecting a battery.
