I recently ordered the DKP6012 CC buck converter module from Amazon:

https://www.amazon.com/gp/product/B071LGTTRN

The buck converter will not output the selected voltage. Here are the settings and measurements I tried:

Input Voltage: 15 Volts (verified)

Output Voltages:

Select 5.00V/1A – Select output mode – Display changes to 3.5V – Measured 3.75V

Select 9.00V/1A – Select output mode – Display changes to 7.19V – Measured 7.74V

Select 12.00V/1A – Select output mode – Display changes to 9.95V – Measured 10.73V

I tried different input voltages, but observed the same results. No load, just multimeter measuring DC volts.

The setting for output volts is different than the displayed output volts, which is also different from the measured volts.

This seems like a defective unit. Is there anything else I can try? I am still within my return window with Amazon.

Thanks,

John
