Valefod 10 Pack DC to DC High Efficiency Voltage Regulator 3.2-35V to 1.25-30V Buck Converter DIY Power Supply Step-Down Module

【High Precision】The buck converter consists of 36u thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects..
【Input Voltage】DC 3.2V to 35V (input voltage must be 1.5V higher than the output voltage, no boost)..
【Output Voltage】DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A..
【Mini Size】45 * 23 * 14 mm (with potentiometer). 10pcs included..
【Easy to DIY】Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step-down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V).

DROK DCDC converter input voltage range is DC 4.5-40v, output voltage range is DC 1.25-37v, the voltage is continuously adjustable. It is a non-isolated buck converter, can dial down voltage from 36v 30v 24v to 12v 5v 3.7v 3.5v 3.3v 2v..
Analog Control: Our DC buck converter is designed with a adjustable potentiometer, the output voltage can be easily and accurately adjusted with a mini screwdriver. Clockwise to step up voltage and counterclockwise to step down voltage..
Protection: This power supply supply step down regulator is with over-temperature and short-circuit protection, which protect your device from damaging and enhance its safety when using..
Low Power-consumption: Although the voltage range is wide, this buck voltage module has a low power consumption of only about 3A when in static state..
Note: Please make sure the input voltage is at least 1.5V greater than output voltage to ensure stable output.
please note that there is no reversed connection protection, so check the polarity of input voltage before power on to avoid burning due to reversed connection.
please add heatsink when the output power is larger than 15W..

...ntrol the temperature in a safe range. During the running power is high, the cooling fan will automatically activate with little noise..
【Easy Operation】 This supply is no need to install, after connecting wire, it can be used to adjust output, which is convenient. The potentiometer is inset into the supply. Only to rotate the potentiometer can adjust output parameter..
【Protection】 Over Load Protection, Over Voltage Protection, Short Circuit Protection, which can protect your device from damage. Note: the default input voltage is 220V, before using, please switching the input voltage to 110V/220V according to your city voltage..
【Wide Application】 This power supply has variable application. It can be used as a 5V 12V 24V 30V 36V 48V power supply for RV, Car, Labtop, Computer, Lab, CCTV, etc. All of our item has 1 year long time warranty guarantee..
