Reliability requirements
1. MTBF: (standards, ambient temperature, load requirements) in accordance with the requirements of the Ministry of Posts and Telecommunications YD/T682-94 for superior products of communication rectification equipment. The MTBF (Mean Time Between Failure) ≥ 50,000 h. The product has to withstand overload, overheating, to change the external environment such as sudden voltage changes.

2. Component selection: components should be selected from famous brand manufacturers with stable quality, and the electrical stress and temperature stress of the components should be adjusted.Derating appropriately, anti-transient design for key components to ensure the reliability of components.

3. Thermal design: The system adopts forced air cooling and a reasonable layout inside the module to reduce the temperature rise of components.

4. Environment-resistant design: The product has strong environmental adaptability, and the temperature and humidity can basically meet the storage requirements of all regions in the country (-20~50℃), the use requirements under simple protection conditions (-20-50℃), can meet the storage and use requirements from cold climate to hot and humid climate.

5. Immunity to electromagnetic environment: Fully consider the complexity of the power grid, improve the product's resistance to electromagnetic environment interference, and make reasonable use of it in the design, use shielding, grounding, transient protection and other design methods to improve the anti-interference ability.
