PDSE1-S5-S15-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, ensure good airflow around the device and consider using a heat sink if operating in high-temperature environments.
• How do I ensure reliable startup and shutdown of the power supply?
  To ensure reliable startup and shutdown, CUI recommends a soft-start circuit to limit inrush current and a shutdown circuit to prevent voltage spikes. Additionally, ensure that the input voltage is within the specified range and that the output is properly decoupled.
• What is the maximum allowable capacitance on the output?
  The maximum allowable capacitance on the output of the PDSE1-S5-S15-S is 220uF. Exceeding this value may cause instability or oscillation in the power supply.
• Can I use this power supply in a high-vibration environment?
  While the PDSE1-S5-S15-S is designed to be rugged, it is not specifically designed for high-vibration environments. If you need to use it in such an environment, CUI recommends additional mechanical support and securing the device to prevent damage or dislodging.
• What is the MTBF (Mean Time Between Failures) of this power supply?
  The MTBF of the PDSE1-S5-S15-S is approximately 1.5 million hours at 25°C, calculated according to MIL-HDBK-217F. However, this value may vary depending on the specific application and operating conditions.
