Description:
This DC-DC Buck ConverterPower Supply Module Current Voltage Meter LCD Display With Case digitally displays output voltage and current draw. DC-DC Buck Converter enables you to monitor how much current your device is drawing while it’s working with the correct voltage. DC-DC Buck Converter helps you determine what AC adapter will work with your project without overheating it. The DC-DC Buck Converter accepts a 60V AC/DC adapter, but we recommend a 36 VDC 5A 120-063 adapter since the output is up to 32 VDC. DC-DC Buck Converter has built-in short circuit protection for safe voltage down conversion.
Specifications:
- Output Voltage: 3~32V adjustable (It can save the last set voltage automatically)
- Input Voltage: 8~60V
- Conversion Efficiency: 95%
- Load Regulation S(I): 0.8%
- Voltage Regulation S(U): 0.8%
- Anti-anti-input: Yes
- Short circuit protection: Yes
How to Use:
The DC-DC Buck Converter with a calibration function, do not worry about the problem of measurement shows inaccurate, if you find that the display is inaccurate or the value of stuck, or left and right buttons can not be mobilized voltage, you can use the following method of calibration.
Voltage calibration method:
Under the no-load conditions, press and hold the left button to connect to the power supply, release the left button, the voltage value of the display begins to flash, measure the output voltage with a multimeter, and press the left and right keys to set the same value with the meter, Such as: multimeter measurement is 12.6V, the module set to 12.6V, it can be automatically saved three seconds, re-power voltage calibration is completed. The error can be calibrated within 0.05V, if the error is bigger, you can try again.
Current calibration method:
After calibrating the voltage, load, first use a multimeter to measure the actual current value, then power off the board, press and hold the right button to connect to the power, release the right button, the screen current value starts flashing, press the left and right button to adjust value the same with the multimeter, for example the multimeter measurement value is 1.8A, the DC-DC Buck Converter Module can be adjusted to display 1.8A, three seconds automatically saved, re-power on the current calibration is completed.
Package Included:
1 x DC-DC Buck Converter 7A DC 60V Adjustable Step-Down Regulator NC Power Supply Module Current Voltage Meter LCD Display - With Case
