10. Vianmääritys
If you encounter issues with your converter, consider the following:
- Ei lähtöä Voltage:
- Tarkista sisääntulo voltage to ensure it is within the 8V-35V range.
- Tarkista tulon napaisuus (punainen plusnappaan, musta miinusnappaan).
- Check for short circuits in the output wiring or load. The device has short-circuit protection, which may temporarily shut down output.
- Ensure the load does not exceed 3A/15W.
- Lähtö Voltage is Unstable or Incorrect:
- Vahvista syöttö voltage vakautta.
- Tarkista löysät liitännät.
- Ensure the device is not overheating. Over-temperature protection may reduce output.
- Laitteen ylikuumeneminen:
- Varmista riittävä ilmanvaihto muuntajan ympärillä.
- Reduce the load if it is consistently near the maximum limits.
