A mini step-down converter that changes the voltage from 4V to 24V - into freely adjustable voltage from 0.85V to 22V with a potentiometer. The system works only as a step down voltage. Possibility to select the voltage by soldering a given jumper: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V. Technical data Maximum output current 3A, continuous: 2.1A Compact dimensions: 20 x 11 x 5mm (L x W x H) Input voltage for pins: GND, IN + Output voltage: GND, V0 + - regulated voltage Output voltage: GND, EN - 6.5V DC voltage. Usage Notes Incorrect connection of the power polarity will damage the inverter - the warranty will not be considered This device is intended for experienced DIY enthusiasts, a basic knowledge of electronics and soldering skills are required. Check the output voltage and adjust the correct potentiometer, and only then connect the receiving device https://elecena.pl/product/22624396/3a-step-down-dc-dc-voltage-buck-converter-module-jumpers-for-voltage-setting 2023-02-23 https://elecena.pl/product/22624396/3a-step-down-dc-dc-voltage-buck-converter-module-jumpers-for-voltage-setting 2025-10-28
