Specifications

Protection Mechanisms

• Input Undervoltage Protection (LUP): Adjustable from 11-125V, default value 11V.
• Output Overvoltage Protection (OUP): Adjustable from 1-130V, default value 130V.
• Output Overcurrent Protection (OCP): Adjustable from 0.01-23A, default value 23A.
• Output Overpower Protection (OPP): Adjustable from 1-1500W, default value 1500W.

Setup

Before connecting the power supply, ensure all components are present and undamaged. The module consists of a main motherboard and a separate display unit. Connections are typically made via ribbon cables and screw terminals.

1. Motherboard Connection: Connect the input power source (12-140V DC) to the "IN" terminals on the motherboard, observing polarity. Connect your load to the "OUT" terminals.
2. Display Unit Connection: Connect the display unit to the motherboard using the provided ribbon cable. Ensure the connection is secure and correctly oriented.
3. Analog Potentiometer Control (Optional): If using analog potentiometers for voltage and current adjustment (e.g., with ZK10022B motherboard), it may be necessary to solder the potentiometers and plug them into the jumper cap. For serial screen or APP/Upper computer control, the jumper cap should be unplugged and the unit powered on again.
4. Serial Communication: For digital communication control, ensure RX and GND are short-circuited for analog potentiometer control, otherwise digital communication is required. The default baud rate is 115200.

Operating Instructions

The ZK-10022 features an intuitive interface for setting output voltage and current. The independent silicone keys and rotary encoder facilitate precise adjustments.

1. Power On: After connecting the input power and load, power on the module. The display unit will illuminate.
2. Adjusting Voltage: Press the "V-SET" button to enter voltage adjustment mode. Use the rotary encoder to increase or decrease the desired output voltage. Press "OK/M" to confirm or exit.
3. Adjusting Current: Press the "I-SET" button to enter current adjustment mode. Use the rotary encoder to set the desired output current limit. Press "OK/M" to confirm or exit.
4. Enabling/Disabling Output: Use the designated output control button (often labeled "ON/OFF" or similar on the display) to enable or disable the power output to the load.
5. Saving Settings: The module supports 11 groups of data storage. Refer to the on-screen prompts or specific button labels (e.g., "M/T" for memory functions) to save and recall frequently used voltage/current settings.
6. Monitoring: The 1.8-inch display provides real-time readings of output voltage, current, and power, along with active protection statuses.

Maintenance

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

• Cleaning: Regularly clean the exterior of the module with a soft, dry cloth. Avoid using liquid cleaners or solvents that could damage the components.
• Ventilation: Ensure the cooling fan and ventilation openings are free from dust and obstructions to prevent overheating. Operate the module in a well-ventilated area.
• Connections: Periodically check all electrical connections for tightness and signs of wear or corrosion.
• Storage: When not in use for extended periods, store the module in a dry, dust-free environment.

Troubleshooting

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

• No Power/Display:
  • Check the input power supply connection and ensure it is within the 12-140V range.
  • Verify that the ribbon cable connecting the display to the motherboard is securely attached.
• Output Not Working:
  • Ensure the output is enabled via the display unit's control button.
  • Check for active protection mechanisms (LUP, OUP, OCP, OPP) indicated on the display. Adjust settings or reduce load if a protection is triggered.
  • Verify load connections are correct and not short-circuited.
• Inaccurate Readings:
  • The module supports calibration. Refer to advanced settings on the display or contact support for calibration procedures if readings are consistently inaccurate.
• Fan Not Running:
  • The fan activates only when temperature exceeds 45°C, current exceeds 2A, or power exceeds 30W. This is normal operation.
  • If conditions are met and the fan still doesn't run, check for obstructions or contact support.
