Feature

●Input voltage: DC 3.2 V to 40 V, input voltage must be higher (1.5 V) than the output voltage.
●Output voltage: DC 1.25 V to 35 V, voltage is freely adjustable, with high efficiency (max. 92%) and max. output current is 3 A.
●Steps: Connect to the power source, adjust the rotator button on the blue potentiometer and monitor voltage with multimeter to get the necessary voltage, turn clockwise to step up voltage and counterclockwise to step down voltage (default voltage setting remains high; you need to contra-rotate about 7-8 circles before the voltage starts to fall, 1 circle means +/- 1 V).
●High precision: Consists of 36u thickened circuit boards, high-Q inductance with lamp indicator and superior solid-state capacitors that can effectively filter out high-frequency noise.
●Exterior dimensions (L x W x H): 5 pieces, 45 x 20 x 14 mm.

Description

Yizhet DC to DC Buck Converter


Voltage regulation Connect the power supply (3-40V), set the blue potentiometer knob (generally turn clockwise to increase the voltage, and counterclockwise to reduce voltage) and monitor the output voltage with a multimeter until it reaches the required voltage.	Wiring mode 1. Solder, solder the power cord directly to the input (output) port 2. Solder the pins that can be inserted through the wires into the pins or inserted into the perforated plate for use; or solder the board immediately after adding the pins.	Voltage regulation When the resistance value of the factory blue potentiometer is maximum, turn the knob counterclockwise after turning on the input, and the output voltage changes after about 78 turns. Connect the power supply (4-35V), set the blue potentiometer knob (usually turn clockwise to amplify it, counterclockwise to decrease it), and use a multimeter to monitor the output voltage until it reaches the required voltage.	Voltage range Input voltage range: DC 3.2-40V (the input voltage must be more than 1.5V higher than the output voltage. It cannot be reinforced) Output voltage range: DC 1.25-35V voltage is infinitely adjustable, high efficiency (maximum 92%) and the maximum output current is 3A.

Precautions:

It is recommended to use a current within 2.5 A for long-term work and add a heatsink (output above 10 W); Since this is a step-down module, please limit the voltage difference to 1.5 V to ensure stable output.

1. This module is an adjustable downward module, and the output voltage can be changed by adjusting the blue adjustable electrical anode on the module. The input and output voltage difference is 2V, and the limit can output a voltage of 1.25V.

2. IN- (input negative), IN+ (input positive), OUT indicated on the module. (Output negative), OUT+ (output positive) must be connected correctly, otherwise the module may be damaged.
