PCN1-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 thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal interface material (TIM) with a thermal conductivity of 1-2 W/m-K should be used between the module and the heat sink.
• How do I ensure reliable start-up and shutdown of the power supply?
  To ensure reliable start-up and shutdown, CUI recommends a soft-start circuit to limit inrush current and a shutdown circuit to prevent voltage spikes. Additionally, a minimum of 10ms delay between power-on and enable signals is recommended.
• What are the derating curves for temperature and altitude?
  CUI provides derating curves for temperature and altitude in the application notes section of their website. The curves provide guidance on reducing output power to ensure reliable operation under extreme environmental conditions.
• Can I use this power supply in a Class I, Division 2 hazardous location?
  The PCN1-S24-D12-S is not certified for use in hazardous locations. However, CUI offers other products that meet the requirements for Class I, Division 2 hazardous locations. Please consult with CUI's sales team for more information.
• What is the MTBF (Mean Time Between Failures) of this power supply?
  CUI provides MTBF data for the PCN1-S24-D12-S in the reliability report, which is available upon request. The MTBF is calculated based on MIL-HDBK-217F and is typically in the range of 1-2 million hours.
