PEME2-S5-D5-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 thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal interface material (TIM) can be used to improve heat transfer between the module and the heat sink.
• How do I ensure reliable operation in high-vibration environments?
  CUI recommends following the recommended PCB mounting and screw torque specifications to ensure the module is securely fastened. Additionally, using a conformal coating and potting the module can help improve reliability in high-vibration environments.
• What is the maximum allowable capacitance for the output filter?
  The maximum allowable capacitance for the output filter is 10uF. Exceeding this value may cause instability or oscillation in the converter.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PEME2-S5-D5-S can be used in a redundant or parallel configuration, but it requires additional external circuitry and careful design consideration to ensure proper operation and fault tolerance.
• What is the typical efficiency of the module at different loads?
  The typical efficiency of the PEME2-S5-D5-S is around 85-90% at full load, and around 80-85% at half load. Efficiency may vary depending on the input voltage, output voltage, and operating temperature.
