Product parameters:

Module properties: Non-isolated buck voltage stabilization module (BUCK)

Input voltage: DC12-75V

Output voltage: DC2.5-50V adjustable (cannot boost when the input voltage is greater than the output voltage)

The maximum output voltage is approximately equal to the input voltage *0.8 times

Output current: 25AMax (if the module temperature exceeds 75 degrees after loading, please add heat dissipation or derating the rating)

Output constant current: 1-25A adjustable

Output power: 600WMax (with a long time of less than 500W, high voltage output measured, such as low voltage output peak current 25A)

Heat dissipation method: Fan heat dissipation

Input undervoltage protection: None

Input overvoltage protection: None (please leave the allowance when used)

Operating frequency: 80Khz

Conversion efficiency: Typical value 95% (efficiency is related to input and output voltage difference and current)

Short circuit protection: There is (currently set constant current value)

Input reverse connection protection: None (please make sure that the positive and negative electrodes are powered on again, or input positive electrodes and string 2 diodes to protect them)

Output anti-rejection: None (such as battery or inductive load that is charged on the load, the positive electrode of the module needs to be added with string 2-electrode protection)

Output indicator: Yes

Module size: 100*60*35mm

Voltage regulation: According to the voltage required by the load, after powering on, the voltmeter is turned on and the output voltage is turned on at the same time (voltage potentiometer) and increase clockwise and reduce it inversely.

Constant current regulation:

The universal meter is short-circuit current regulation method: the output voltage of the module is adjusted to 5V, and the current potentiometer is twisted in reverse clockwise for about 20 turns (at this time, the module output has no voltage and then the output is output after 2 to 3 turns). The universal meter is turned on the current gear, and the meter is connected to the output end of the module, and the current potentiometer is twisted clockwise until the universal meter displays the current value you need.

The series ammeter adjustment method: adjust the output voltage to the voltage value required by the load, screw the current potentiometer for about 20 turns in the reverse clock hand (preset to the minimum), and connect the series ammeter to the load (if the battery needs a low battery to use a battery, the fully charged battery will not pull the current). Switch the current potentiometer clockwise until the ammeter shows the current value required by the load.
