7. Maintenance
7.1 Cooling System
The device features an optimized dual-fan thermal architecture with two intelligent temperature-controlled PWM fans. These fans provide stepless speed regulation, utilize double ball bearings for extended lifespan, and operate with low noise. One fan focuses on direct cooling of high-heat components (MOSFETs, inductors), while the other optimizes heat dissipation across the entire heatsink. This system reduces operating temperature by 20-30% under typical conditions, supporting continuous full-power operation.

Regularly check the fan vents for dust accumulation. Clean with compressed air if necessary to ensure optimal airflow and cooling performance.
7.2 Cleaning
Wipe the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from all power sources before cleaning.
8. Troubleshooting
- No Power on Display:
- Check input power connections and ensure correct polarity.
- Verify the input voltage is within the specified range (12.00V ~ 90.0V DC).
- Ensure the main power switch on the board is ON.
- Output Voltage Not Reaching Desired Value:
- Confirm the input voltage is sufficiently higher than the desired output voltage, as this is a step-down converter. The maximum output is ~94.5% of input.
- Check for any active over-voltage protection (S-OUP) or over-current protection (S-OCP) settings that might be limiting the output.
- Output Current Limited:
- Verify the I-SET value is set correctly.
- Check for active over-current protection (S-OCP) or over-power protection (S-OPP) settings.
- Ensure the load is not drawing more current than the device can supply.
- Display Orientation Issue:
- If the display is not in the desired orientation, long press the SW button on the main UI to rotate it.
9. User Tips
- Save Presets: Utilize the 10 data storage groups to save frequently used voltage and current settings for quick recall, especially useful for repetitive tasks or testing different components.
- Monitor Temperature: Keep an eye on the temperature readings on the display, especially during high-load operations, to ensure the device remains within safe operating limits. The intelligent cooling system is designed to manage heat, but good ventilation is always recommended.
- Remote Control Convenience: For applications where the power supply is in an inaccessible location or for quick adjustments, consider integrating the optional remote control modules.
- Firmware Updates: Check the manufacturer's website periodically for firmware updates to ensure you have the latest features and performance improvements.
