Description
This device is a dc buck converter that can step down 36v to 48v to 5v, 12v, and 24v. It also has an adjustable voltage transformer board that can regulate the voltage to within 0.8% of the set voltage. The current is adaptive to the load and is not adjustable. The dimensions are 62mm*44mm*18mm and the weight is 45g.
Output current: Maximum 7A, best to use within 5A. If the temperature is a little bit too high, please Use heat reduction measures. The current is adaptive to the load and is not adjustable.
Load regulation S (I) = 0.8%, voltage regulation S (u) = 0.8%
Dimension: 62mm*44mm*18mm
Weight:45g
If used for charging, when charging is completed, Please cut off the battery end first, then disconnect the input terminal to prevent the current flowing back to damage the module! Or add a backflow prevention diode at the outputCalibration instructions: This module has a calibration function. If the display is not accurate or the display value is stuck, or the left/right button malfunctions, you can use following method to calibrate.
Voltage calibration: Disconnect the load and input power, hold down the left button while connecting power ,then release the button. The display starts to flash with voltage value. Use a multimeter to measure the output voltage, Press left or right button to match the multimeter value,it'll auto save in three seconds. Reconnect the power and it's done. After calibration, the error should be within 0.05V, if for any reason, it doesn't meet your expectation, please do the calibration again.
Current calibration: After the voltage is calibrated, connect the load, first use the multimeter to measure the actual current value, then disconnect the power, hold down the right button while connecting the power supply, release the button, the display starts to flash with current value Press left or right button to match the measured current value, it'll auto save in three seconds, Reconnect the power and it's done.
