7. ట్రబుల్షూటింగ్
The SK-120 is equipped with multiple protection features to safeguard the device and connected equipment. If the module stops functioning or displays an error, check the following:
- అండర్ వాల్యూమ్tagఇ రక్షణ (UVP): ఇన్పుట్ వాల్యూమ్ అయితేtage drops below the set threshold (default 5.5V), the output may shut off. Verify your input power source.
- ఓవర్ వాల్యూమ్tagఇ రక్షణ (OVP): అవుట్పుట్ వాల్యూమ్ అయితేtage exceeds the set threshold (default 38V), the output will be disabled. Check your voltage settings and load.
- ఓవర్ కరెంట్ ప్రొటెక్షన్ (OCP): If the output current exceeds the set threshold (default 6.2A), the output will be disabled. Reduce the load or check for short circuits.
- అధిక-ఉష్ణోగ్రత రక్షణ (OTP): If the internal temperature exceeds the set threshold (default 95°C), the output will shut off. Ensure proper ventilation and reduce load if necessary.
- Over-power Protection (OPP): If the output power exceeds the set threshold (default 125W), the output will be disabled. Reduce the load.
- Anti-reverse Connection: The module has protection against reverse input polarity. However, ensure correct polarity for output connections, especially when charging batteries, as output reverse connection protection is not present.
If issues persist after checking these points, refer to the contact information in the Support section.
