DROK DC Buck Converter Adjustable, DC Voltage Regulator Adjustable 4.5-40V to 1.25-37V (36V 24V 12V 9V 5V 3V) Variable Voltage Stabilizer Power Supply Volt Reducer Step Down Transformer
Non-isolated LM2596 Buck Converter, Dial Down Volt 36V 30V 24V to 12V 5V 3.7V 3.5V 3.3V 2V.
Analog Control: using a mini screwdriver to increase or decrease output voltage by adjusting the potentiometer, clockwise to step up voltage and counterclockwise to step down voltage.
With over-temperature and short-circuit protection, hence it is safe to use.
Wide Voltage input of 4.5-40V and output of 1.25-37V but has low power-consumption.
Easy to make it work and convenient to accurately adjust the output voltage with a mini screwdriver.
