PESE1-S24-S5-M-TR 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, ensure good airflow around the device and consider using a heat sink if operating in high-temperature environments.
• How do I ensure reliable operation in high-vibration environments?
  CUI recommends following the recommended PCB mounting and screw torque specifications to ensure the device is securely fastened. Additionally, consider using a conformal coating to protect the device from moisture and vibration-induced stress.
• What is the maximum allowable voltage derating for this power supply?
  CUI recommends derating the input voltage by 10% to ensure reliable operation and to account for voltage tolerances. For example, if the rated input voltage is 24V, the maximum allowable voltage would be 21.6V.
• Can I use this power supply in a redundant or parallel configuration?
  Yes, the PESE1-S24-S5-M-TR can be used in a redundant or parallel configuration, but it's essential to follow CUI's guidelines for synchronization and current sharing to ensure reliable operation and to prevent damage to the devices.
• What is the typical MTBF (Mean Time Between Failures) for this power supply?
  CUI provides an MTBF rating of 1.5 million hours at 25°C, calculated according to MIL-HDBK-217F. However, this rating may vary depending on the specific application and operating conditions.
