6. Setup

Before connecting, ensure all power sources are off. Identify the input and output terminals on the module. The input terminals are labeled 'IN+' and 'IN-', and the output terminals are labeled 'OUT+' and 'OUT-'.

1. Input Connection: Connect your DC power source (8-60V) to the 'IN+' (positive) and 'IN-' (negative) terminals. Ensure a secure connection.
2. Output Connection: Connect your load or device to the 'OUT+' (positive) and 'OUT-' (negative) terminals.
3. Power On: Once all connections are secure, apply power to the input. The LED display should illuminate.

7. Operating Instructions

The module operates in two modes: Simple Mode (default) and Full Function Mode. The 4-digit LED display shows various parameters, and buttons allow for adjustment and mode selection.

7.1. Button Functions

• SET Button: Used to enter parameter setting mode.
• UP/DOWN Buttons: Used to adjust values in setting mode.
• OK Button: Confirms settings and switches output ON/OFF.
• IN/OUT Button: Toggles between displaying input and output parameters.

7.2. Setting Output Voltage and Current

1. Press the SET button to enter voltage setting mode. The voltage value on the display will flash.
2. Use the UP and DOWN buttons to adjust the desired output voltage.
3. Press SET again to switch to current setting mode. The current value will flash.
4. Use the UP and DOWN buttons to adjust the desired output current.
5. Press OK to confirm the settings and exit setting mode.

7.3. Displaying Parameters

• Short press the OK button to toggle between displaying output voltage and current.
• Long press the OK button (for 3 seconds) to enable/disable automatic cycling display of voltage, current, power, and capacity.
• Use the IN/OUT button to switch between input and output parameter displays.

7.4. Memory Function

The module can store up to 10 groups of parameters. To save current settings:

1. Adjust the desired voltage and current.
2. Long press the SET button until a memory location (e.g., "01") appears.
3. Use UP/DOWN to select a memory location (00-09).
4. Press OK to save the settings to the selected location.

To recall saved settings, long press SET, select the desired memory location, and press OK.

7.5. Automatic Output on Power-Up

The module can be configured to automatically output power when turned on. Refer to the full function mode instructions for detailed setup of this feature.

8. Maintenance

• Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Regularly check all wiring connections to ensure they are secure and free from corrosion.
• Ensure the cooling fan is unobstructed and operating correctly. A malfunctioning fan can lead to overheating.
• Store the module in a dry, cool environment when not in use.

9. Troubleshooting

• No Output/Display:
  • Check input power supply. Ensure it is within the 8-60V range and connected correctly.
  • Verify the fuse (20A) is intact. Replace if blown.
  • Ensure the output is enabled (check the OUT indicator). Press the OK button to toggle output.
• Overheating:
  • Check if the cooling fan is spinning. If not, ensure it's connected and functional.
  • Reduce the load or ensure the output current does not exceed 15A.
  • Ensure adequate airflow around the module.
• Incorrect Voltage/Current Readings:
  • Verify the calibration of external measurement devices if comparing readings.
  • Ensure proper connections to the module.
• Output Voltage Not Stable:
  • Check for loose connections or faulty wiring.
  • Ensure the input voltage is stable and within the specified range.
