PSK-5D-24 - CUI Inc.

PSK-5D-24 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 2 oz copper thickness is recommended. Additionally, ensure a minimum of 1 mm clearance around the module to allow for airflow and heat dissipation.
• 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. Additionally, a minimum of 10 ms delay between startup and shutdown is recommended to prevent damage to the module.
• What is the maximum allowable capacitance on the output?
  The maximum allowable capacitance on the output is 2200 uF. Exceeding this value may cause instability or oscillation in the power supply.
• Can I use the PSK-5D-24 in a high-vibration environment?
  Yes, the PSK-5D-24 is designed to withstand high-vibration environments. However, CUI recommends following the recommended PCB layout and securing the module with screws or adhesive to prevent mechanical stress.
• How do I troubleshoot common issues such as overvoltage or undervoltage faults?
  CUI recommends using an oscilloscope to monitor the output voltage and current. Check for any signs of oscillation, noise, or voltage droop. Consult the datasheet and application notes for troubleshooting guides and fault detection methods.
