PSK-60-12-T 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 good airflow around the module and consider adding a heat sink if operating in high ambient temperatures.
• How do I ensure reliable start-up and shutdown of the power supply?
  To ensure reliable start-up and shutdown, CUI recommends a soft-start circuit to limit inrush current and a power-good signal to monitor the output voltage. 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?
  CUI recommends a maximum output capacitance of 2200uF to ensure stability and prevent oscillation. Exceeding this value may lead to instability or even damage to the power supply.
• Can I use this power supply in a high-vibration or high-shock environment?
  While the PSK-60-12-T is designed to meet standard vibration and shock requirements, CUI recommends additional testing and validation for extreme environments. Consider adding mechanical reinforcement, such as potting or conformal coating, to ensure reliability.
• How do I troubleshoot common issues, such as overvoltage or undervoltage faults?
  CUI recommends consulting the application notes and troubleshooting guide provided with the datasheet. Additionally, ensure that the input voltage is within the specified range, and check for proper output loading and decoupling.
