: While the integrated heatsink supports high loads, running continuous configurations above 35W or 4A requires external active cooling (such as an added fan) to prevent heat fatigue.
| Problem | Potential Cause(s) | Solution | | :--- | :--- | :--- | | | Input voltage is too low, or connection is reversed. | Check input voltage polarity and level (must be ≥6.0V). Use the input reverse protection feature to your advantage, but correct the connection first. | | Output current display is inaccurate | The module needs calibration or is measuring in a constant voltage mode. | Perform a proper two-point current calibration as described above. | | Module overheats or fan runs constantly | Output load is near the maximum 80W limit, or ambient temperature is high. | Reduce the load or improve airflow around the module. The fan activating above 50°C is normal behavior. | | Output shuts down unexpectedly | One of the protection thresholds (OVP, OCP, OPP, UVP, OTP) was triggered. | Check the LCD for a protection code (e.g., OVP , OCP ). Identify which threshold was exceeded and adjust your settings or load accordingly. Press any key to exit the protection interface. | | Soft start fails with heavy loads | The inrush current of a large capacitive load is too high. | The soft-start function may not work with very large loads. Consider using a separate pre-charge circuit or reducing the initial load. | | Module won't calibrate | Calibration steps were not followed correctly, or the output was not properly loaded during current calibration. | Carefully repeat the calibration steps, ensuring you are using a reliable multimeter and, for current calibration, a proper load in series with the meter | | Output voltage is unstable | Input power supply is insufficient or unstable; or the load is highly inductive or capacitive. | Ensure your power supply can deliver enough current. Try adding a filter capacitor to the input or output of the module. | Hardware Architecture and Safety Features The ZK5KX is
