PQME3-D24-S24-M Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  CUI recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible. Additionally, it's recommended to use a common mode choke and a 10uF capacitor on the input side to reduce EMI.
• Can I use this module in a high-temperature environment?
  While the PQME3-D24-S24-M is rated for operation up to 80°C, it's recommended to derate the output power by 2.5% per degree above 60°C to ensure reliable operation. Additionally, the module's reliability may be affected by prolonged exposure to high temperatures.
• How do I ensure the module meets my specific safety certifications (e.g. UL, CE, etc.)?
  CUI provides a list of approved safety certifications for the PQME3-D24-S24-M. However, it's the customer's responsibility to ensure that their specific application meets the required safety standards. CUI recommends consulting with a safety expert or testing agency to ensure compliance.
• What is the typical MTBF (Mean Time Between Failures) for this module?
  CUI estimates the MTBF for the PQME3-D24-S24-M to be around 1.5 million hours, based on MIL-HDBK-217F calculations. However, this value may vary depending on the specific application and operating conditions.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PQME3-D24-S24-M can be used in a redundant or parallel configuration, but it's essential to ensure that the modules are properly synchronized and that the system is designed to handle the increased power and heat dissipation.
