PDME2-S24-D12-S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a PCB layout with a solid ground plane and a thermal pad connected to a heat sink or a thermal via to ensure efficient heat dissipation. A minimum of 2oz copper thickness is recommended for the PCB.
• How does the module handle input voltage transients and spikes?
  The PDME2-S24-D12-S has built-in input voltage transient protection, which includes a TVS diode to absorb voltage spikes and a filter to reduce noise. However, it's still recommended to add external protection components, such as a fuse and a varistor, to ensure the module's reliability.
• What is the derating curve for the module's output power versus ambient temperature?
  CUI provides a derating curve in the datasheet, which shows the maximum output power versus ambient temperature. As a general guideline, the output power should be derated by 2.5% per degree Celsius above 40°C to ensure reliable operation.
• Can the module be used in a redundant or parallel configuration for higher power or redundancy?
  Yes, the PDME2-S24-D12-S can be used in a redundant or parallel configuration, but it requires careful design and implementation to ensure proper synchronization and control. CUI recommends consulting with their application engineers for guidance on such configurations.
• What is the MTBF (Mean Time Between Failures) rating for the module?
  CUI provides an MTBF rating of 1.5 million hours at 40°C, calculated according to MIL-HDBK-217F. However, the actual MTBF may vary depending on the application, operating conditions, and quality of the PCB assembly.
