DC‑DC 8‑60V To 3‑32V Max 7A Adjustable Buck Step Down Power

Features:
With
transparent
acrylic shell,
easy to read while protecting the module
Using LCD display screen, Voltage and Current can be displayed
simultaneously
Using button adjustable voltage, left button to reduce the voltage, the right button to increasing voltage. press button one time can adjust 0.04V voltage, press and hold more than 1 second to quickly adjust voltage.
Can withstand 100,000 presses; Compared with similar potentiometer voltage regulation more convenient and fast.
Only can be used as a step down converter, and input voltage should be >1V higher than output.

Specifications:
Input Voltage: DC 8V~60V (Recommended within 55V, Input voltage must be higher than the output voltage 1V above)
Output Voltage: DC 3V~32V Continuously adjustable
(It can save the last set voltage automatically)
Output Current: Max 7A (Recommended use within 5A, Please pay attention to heat dissipation.)
Accuracy: 1%, the voltage three bits display, the current two bits display, the unit is "A".
Input Anti-reverse Protection: Yes
Short Circuit Protection: Yes
Conversion Efficiency: Max up to 95%
Load Regulation S(I): ≤0.8%
Voltage Regulation S(U): ≤0.8%
Size: 62 x 44 x 18mm / 2.59 x 1.73 x 0.7in
Weight: 67g
Voltage Calibration Method:
Power-off no load status, press and hold the left button access the power supply, release the left button, the display voltage starts flashing, then using multimeter measured the output terminal voltage, press the left and right keys to adjust the module display voltage value is the same as the multimeter display voltage value, for example: multimeter measurement is 12.6V, then the module can be transferred to display 12.6V, three seconds automatically save, re-power that voltage calibration is complete. The error can be calibrated within 0.04V, if the error is greater, you can try to calibrate again.
Current Calibration Method:
After calibrated the voltage is completed, connect the load, with a multimeter to measure the actual current value, power off the power supply, then press and hold the right button access the power supply, release the right button, the display current value starts to flash, press the left and right keys to adjust the module display current value is the same as the multimeter display current value, such as: multimeter measurement is 1.8A, then the module can be transferred to display 1.8A, three seconds automatically save, re-power that current calibration is complete.

Package Includes:
1 x Step-Down Module Kit
1 x Acrylic shell
Note:
If it is used
for charging, after charging, please first disconnect the battery
end and then the input end to prevent the battery
from damaging the module by backflow. Or at the output
end add a diode preventing backflow
