This is the Constant Voltage and Current Output module. Use this module to step down an input voltage between 7-30V to an output voltage of 5-30V. Two onboard potentiometers can be used to set the desired output voltage and current by the user. The module can also regulate the maximum output current to be supplied between 0.2A to 5A. This power regulator comes with a nice big LED Display on top which displays the output voltage and current. Great for monitoring the current and voltage being drawn by your load - project, motor, robot, etc. The display also lets you adjust the required output current and voltage easily. These features make this module a great power supply for electronic projects, battery chargers, and led drivers. Please use an external heatsink and fan if you are drawing high power and temperature for the module increases beyond 65 degrees Celsius.
