Variable Power Supply Board-1.2V to 37V – 1.5A
A Variable Power Supply Board-1.2V to 37V – 1.5A is one that includes some means for the user to easily adjust the output voltage and sometimes the current. Adjustment is most often accomplished with a potentiometer, but may also be done with an analog control voltage, a digital input, an autotransformer, etc.
This is a variable power supply DC-DC buck converter step-down power module with the high-precision potentiometer, capable of driving a load up to 1.5A with high efficiency, which can work with Freeduino UNO, other mainboards, and basic modules. When the output current keeps greater than 1.2A, It has a heat sink to control the heat. This device is internally compensated to minimize the number of external components to simplify the power supply design. Since the LM317 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages.
