DC-DC Convertor Precision Adjustable Voltage Regulator Power Module Buck Board DC7-50V to DC3-45V Step-down Power Supply Board
Using the TL431 precision regulator as the core, the multi-turn adjustable precision resistance sampling output voltage is adjustable between 3V-40V. The voltage fluctuates within 0.2V. Use high voltage and high power output tube, wide input voltage range, large output current.
Heat sinks need to be added to the power tube under high current conditions
When the module voltage is adjusted to 5V, the buyer can adjust the voltage they need according to their own, adjust the voltage method: connect the input, the output is not connected, adjust the adjustable resistance on the board while measuring the output voltage until it is adjusted to the voltage they need, connect the load. Measure the output voltage again, make a second adjustment if there is an error, and do not remove the load during the second adjustment.
