6. Operating Instructions

This section details how to operate the ZK-5KX converter, including setting voltage and current limits.

Figure 6.1: Normal operating interface and setting interface.

6.1. Power On/Off

• After connecting the input power, the LCD will display information.
• Short press the Rotary Encoder to toggle the output ON or OFF. The 'ON' indicator light will show the output status.

6.2. Display Modes

• Short press the SW Key to cycle through different display parameters on the main interface (e.g., Input Voltage, Output Voltage, Output Current, Output Power, Output Capacity, Output Time, Temperature).
• Short press the U/I Key to switch between displaying input voltage/current and output voltage/current.

6.3. Setting Output Voltage and Current

1. From the main interface, long press the U/I Key to enter the setting mode. The 'SET' indicator will appear, and the output voltage value will blink.
2. Rotate the Rotary Encoder to adjust the desired output voltage.
3. Short press the Rotary Encoder to move the cursor to the next digit for fine adjustment, or to switch between setting voltage and current.
4. Once the voltage is set, rotate the Rotary Encoder to adjust the desired output current limit.
5. Long press the U/I Key again to save the settings and exit the setting mode. The module will resume normal operation with the new parameters.

6.4. Calibration

The module supports calibration for voltage and current. For precise calibration, a trusted multimeter is recommended. Refer to advanced user guides or contact support for detailed calibration procedures.

7. Protection Mechanisms

The ZK-5KX converter includes comprehensive protection features to safeguard the module and connected devices:

• Input Anti-Reverse Connection: Protects against damage from incorrect input polarity.
• Output Anti-Backflow: Prevents current from flowing back into the module from the output.
• Input Undervoltage Protection: Adjustable from 5.8-36V (default 5.8V). Shuts off output if input voltage drops below the set threshold.
• Output Overvoltage Protection: Adjustable from 0.6-36V (default 36V). Shuts off output if output voltage exceeds the set threshold.
• Output Overcurrent Protection: Adjustable from 0-5A (default 5A). Shuts off output if output current exceeds the set threshold.
• Output Overpower Protection: Adjustable from 0-80W (default 80W). Shuts off output if output power exceeds the set threshold.
• Overtemperature Protection: Adjustable from 80-110°C (default 110°C). Shuts off output if internal temperature exceeds the set threshold.
• Timeout Protection: Adjustable from 0 to 100h (disabled by default). Shuts off output after a set operating time.
• Overcapacity Protection: Adjustable from 0 to 60Ah (disabled by default). Shuts off output after a set accumulated output capacity.

8. Maintenance

The Hosyond ZK-5KX is designed for reliable operation with minimal maintenance.

• Cooling Fan: The intelligent temperature-controlled fan automatically activates when the module temperature exceeds 50°C or the current exceeds 1A. Ensure the fan's air intake and exhaust are not obstructed to allow for proper heat dissipation.
• Cleaning: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquids or abrasive cleaners.
• Storage: Store the module in a dry, cool environment when not in use.

9. Troubleshooting

If you encounter issues with your ZK-5KX converter, consider the following:

• No Power/Display: Check the input voltage connections and ensure the input voltage is within the 5V-30V DC range. Verify power supply functionality.
• No Output: Ensure the output is turned ON (short press the Rotary Encoder). Check if any protection mechanisms (e.g., overvoltage, overcurrent) have been triggered. Verify load connections and ensure the load is not short-circuited.
• Unstable Output: Check for loose connections. Ensure the input power supply can provide sufficient current for the desired output. Verify that the load requirements are within the module's specifications.
• Fan Not Running: The fan is temperature-controlled and will only activate when the module's temperature exceeds 50°C or the output current exceeds 1A. This is normal operation.
• Inaccurate Readings: If output voltage or current readings appear inaccurate, consider performing a calibration using a precise multimeter.

If problems persist after attempting these steps, please contact customer support.
