PEM2-S24-S24-S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a 2-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 1 oz copper thickness is recommended. Ensure good airflow around the module and avoid blocking the vents.
• How do I ensure reliable start-up and shutdown of the PEM2-S24-S24-S?
  Implement a soft-start circuit to limit inrush current during start-up. For shutdown, ensure a gradual decrease in input voltage to prevent voltage spikes. Consult the datasheet for specific guidelines.
• What are the EMI filtering and shielding recommendations for the PEM2-S24-S24-S?
  Use a combination of common-mode chokes, X-capacitors, and Y-capacitors for EMI filtering. Shielding can be achieved with a metal enclosure and proper grounding. Consult CUI's application notes for detailed guidance.
• Can I use the PEM2-S24-S24-S in a redundant or N+1 configuration?
  Yes, the PEM2-S24-S24-S can be used in redundant or N+1 configurations. However, ensure proper synchronization and control of the modules to prevent instability and overheating. Consult CUI's application notes for guidance on redundant configurations.
• What are the derating guidelines for the PEM2-S24-S24-S in high-temperature environments?
  Derate the output power by 2.5% per degree Celsius above 40°C. Ensure good airflow and consider using a heat sink or thermal interface material to improve heat dissipation.
