LTE Modem 4G: Humidity Resilience

A crucial aspect of the SeDTU300 series is its LTE Modem 4G‘s ability to operate in high humidity environments. The device is designed to function in environments with 5% to 95% relative humidity, non-condensing. This means that the LTE Modem 4G can withstand high levels of humidity without the risk of condensation forming on its components, which could lead to short-circuits or corrosion.

Ensuring Non-Condensing Operation

To maintain the LTE Modem 4G’s non-condensing operation in high humidity environments, several factors are considered:
1. Full metal chassis with natural heat dissipation, ensuring that the device remains cool and prevents condensation.
2. Protective coatings on electronic components that repel moisture and prevent corrosion.
3. IP30 protection level, ensuring protection against solid objects larger than 2.5mm and reducing the risk of moisture ingress.

Testing and Certification

The SeDTU300 series and its LTE Modem 4G undergo rigorous testing and certification processes to ensure reliability and resilience in high humidity environments. This includes exposure to 95% relative humidity for extended periods to verify that the LTE Modem 4G continues to function without any condensation-related issues. The device complies with CCC and RoHS certifications, further attesting to its quality and reliability.

Conclusion

The SeDTU300 series industrial-grade 4G DTU by Xiamen Key-IOT Technology Co., Ltd. features an LTE Modem 4G that demonstrates exceptional resilience in high humidity environments, with the ability to operate in up to 95% non-condensing relative humidity.
