PDME2-S24-D15-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 1 oz 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 start-up and shutdown of the module?
  To ensure reliable start-up and shutdown, CUI recommends a soft-start circuit to limit inrush current and a shutdown circuit to prevent back-feeding of the input voltage. Additionally, a minimum input capacitance of 10uF is recommended to ensure stable operation.
• What is the maximum allowable output capacitance for this module?
  The maximum allowable output capacitance for the PDME2-S24-D15-S is 220uF. Exceeding this value may cause instability or oscillation in the output voltage.
• Can I use this module in a high-vibration or high-shock environment?
  While the PDME2-S24-D15-S is designed to meet standard industrial vibration and shock requirements, CUI recommends additional mechanical support and fixation to ensure reliable operation in high-vibration or high-shock environments.
• How do I troubleshoot common issues such as output voltage deviation or module failure?
  CUI recommends following a systematic troubleshooting approach, starting with input voltage and current measurements, followed by output voltage and current measurements. Additionally, checking the module's thermal performance and ensuring proper PCB layout and thermal management can help identify the root cause of the issue.
