The ZK-5KX is a fully programmable, digitally controlled buck-boost converter module, often branded under the WUZHI label and available through major retailers like AliExpress, Amazon, and Newegg. Its primary function is to take a DC input voltage and provide a regulated output voltage that can be either lower (buck) or higher (boost) than the input, within its specified limits. This "laboratory power supply" is a powerful and compact tool for the workbench.

Up to 80W (natural convection), higher with active cooling. Voltage Resolution: 0.01V Current Resolution: 0.001A Efficiency: ~88%

The ZK-5KX is robustly protected, but understanding these features helps in troubleshooting:

Press the to jump the cursor left or right to target the specific digit slot (hundreds, tens, units, or decimals).

Operating the device is straightforward once you understand the controls:

Output voltage calibration corrects the module across its entire range. Perform this calibration in two steps, ideally with a load or by following the prompts.
