Manual — Zk5kx

(2s) the encoder again to exit setting mode and save settings. 3.2. Adjusting Protection Parameters (OVP/OCP/OPP)

The ZK-5KX is a highly capable and feature-rich power management solution. As a , it offers precision, flexibility, and robust protections typically found in much larger and more expensive laboratory units. Whether you are a professional or a hobbyist, understanding this manual will enable you to master the ZK-5KX and make it an indispensable tool in all your electronics projects.

the encoder for 3 seconds to enter the protection setting interface. Use the encoder to adjust the following: LVP (Low Voltage Protection): Set input cutoff voltage. OVP (Over Voltage Protection): Set maximum output voltage. OCP (Over Current Protection): Set maximum output current. OPP (Over Power Protection): Set maximum output power. OAP (Over Capacity Protection): Limits the Amp-hours. OHP (Over Time Protection): Limits runtime. Long Press for 3 seconds again to save and exit. 3.3. Battery Charging Application zk5kx manual

This section details how to perform the essential operations of the ZK-5KX.

Press the like a button to move the flashing cursor left or right across the digits. This lets you jump quickly between major values (1.0V steps) and minor values (0.01V steps). (2s) the encoder again to exit setting mode

The original details its 0.6–36V output capabilities, constant current/constant voltage (CC/CV) modes, and complex parameter menus. This comprehensive technical manual serves as a definitive guide to wiring, operating, programming, and calibrating your ZK-5KX module. Technical Specifications & Hardware Layout

| 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. | As a , it offers precision, flexibility, and

According to standard instructions, the initial boot sequence should follow this order:
