Yizhet 5 Pack Buck Converter, DC to DC, High Efficiency Voltage Regulator, 3.0 40V 1.5 35V, Adjustable Power Supply Module

Input Voltage range: The Input voltage range is DC 3 V to 40 V. Note: Input voltage must be 1.5 V higher than output voltage, no boost. Output Voltage range: The output voltage range is DC 1.5 V to 35 V and is continuously adjustable, with a maximum output current of 3A. Easy to DIY Manually: Connect the power supply, monitor the voltage with a multimeter, adjust the swirl button on the blue potentiometer to obtain the required voltage, boost clockwise and boost counterclockwise. Note: The factory default setting is 18V. Before the voltage starts to drop, you need to rotate in the reverse direction for about 7-8 revolutions, 1 revolution means +/- 1V High Precision and Quality: The buck converter consists of a 36u thick circuit board with high Q inductors with high power output LED indicators, suitable for various electronic projects. Quantity: 5 piecess; Size: 43 * 21 * 14 mm (with potentiometer).Hurry up to add a shopping cart and click to buy!
