• Output Overpower Protection (OPP): Adjustable from 1-1500W, with a default value of 1500W.

5. Setup

Follow these steps to set up your ZK-10022 power supply module:

1. Unpacking: Carefully remove all components from the packaging. Verify that you have the main motherboard and the LCD display module.
2. Connecting Display Module: Connect the ribbon cable from the LCD display module to the corresponding port on the main motherboard. Ensure the connection is secure and correctly oriented.
3. Input Power Connection: Connect your DC input power source (12-140V) to the "IN" terminals on the main motherboard. Observe correct polarity (+ and -).
4. Output Load Connection: Connect your load to the "OUT" terminals (0-125V) on the main motherboard. Again, ensure correct polarity.
5. Optional Potentiometer Connection: If using external analog potentiometers for voltage and current control, connect them to the designated ports on the motherboard. Refer to Figure 5.1 for connection points. Ensure the jumper cap is removed if using serial communication for control.

6. Operating Instructions

The ZK-10022 features an intuitive interface for setting voltage and current. The LCD screen provides real-time feedback on output parameters.

6.1 Basic Operation

1. Power On: After connecting input power and load, the LCD screen will illuminate.
2. Voltage Adjustment: Press the "V-SET" button to enter voltage setting mode. Use the rotary encoder to adjust the desired output voltage. Press "OK/1" to confirm and exit.
3. Current Adjustment: Press the "I-SET" button to enter current limit setting mode. Use the rotary encoder to adjust the desired output current limit. Press "OK/1" to confirm and exit.
4. Output Enable/Disable: Use the dedicated ON/OFF button (often labeled with a power symbol) to enable or disable the output.

6.2 Advanced Features

• Data Group Storage: The module supports 11 groups of data storage. Refer to the specific button (e.g., "M/T" or similar) and screen prompts to save and recall your frequently used voltage and current settings.
• Buzzer Control: The integrated buzzer provides audible feedback. Consult the on-screen menu or specific button combinations to enable or disable the buzzer as desired.
• Serial Communication: For advanced control and integration, the module supports serial communication via the MODBUS protocol. Ensure the baud rate of your serial device matches the power board's default (115200, adjustable).

7. Maintenance

Proper maintenance ensures the longevity and reliable operation of your ZK-10022 power supply:

• Cleaning: Regularly clean the module with a soft, dry cloth. Avoid using liquids or abrasive cleaners. Ensure the device is powered off and disconnected from all sources before cleaning.
• Ventilation: Ensure adequate airflow around the module, especially around the cooling fan. Do not obstruct the fan or ventilation openings. The cooling fan activates automatically when temperature exceeds 45°C, current exceeds 2A, or power exceeds 30W to prevent overheating.
• Storage: When not in use for extended periods, store the module in a cool, dry place, away from direct sunlight and extreme temperatures.
• Connection Integrity: Periodically check all input, output, and display connections to ensure they are secure and free from corrosion.

8. Troubleshooting

If you encounter issues with your ZK-10022 power supply, refer to the following common troubleshooting steps:

• No Display/No Power:
  • Check input power source: Ensure it is within the 12-140V range and correctly connected.
  • Verify display module connection: Ensure the ribbon cable is securely connected to both the main board and the display.
• No Output Voltage/Current:
  • Check output enable: Ensure the output is enabled via the ON/OFF button.
  • Verify load connection: Ensure the load is correctly connected and not short-circuited.
  • Check protection settings: Review OVP, OCP, and OPP settings. If the output is tripping, these protections might be active. Adjust limits if necessary.
• Incorrect Voltage/Current Reading:
  • Perform calibration: The module supports calibration for output voltage and current accuracy. Refer to the on-screen menu for calibration procedures.
  • Check connections: Loose or poor connections can affect readings.
• Overheating:
  • Ensure proper ventilation: Clear any obstructions around the module and fan.
  • Check fan operation: Verify the cooling fan is spinning when conditions (temperature > 45°C, current > 2A, or power > 30W) are met.
  • Reduce load: Operating at the upper limits of power/current for extended periods can cause heat buildup.
