PSK-15D-12-T - CUI Inc.

PSK-15D-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. For thermal management, a heat sink with a thermal interface material (TIM) can be used to reduce thermal resistance.
• How do I ensure reliable soldering and avoid cold solder joints?
  CUI recommends using a soldering iron with a temperature range of 250°C to 270°C. Apply a small amount of solder paste to the PCB pads and component leads. Use a gentle touch and avoid applying excessive pressure, which can cause cold solder joints.
• What is the maximum allowable voltage derating for this power supply?
  CUI recommends derating the output voltage by 10% to ensure reliable operation and to account for any voltage drops in the system. For example, if the rated output voltage is 12V, the maximum allowable voltage derating would be 10.8V.
• Can I use this power supply in a high-altitude or high-temperature environment?
  The PSK-15D-12-T is designed for operation up to 5,000 feet (1,524 meters) above sea level. For high-altitude or high-temperature applications, CUI recommends consulting with their application engineers to determine the suitability of the power supply and any necessary derating or modifications.
• What is the MTBF (Mean Time Between Failures) rating for this power supply?
  CUI does not provide a specific MTBF rating for the PSK-15D-12-T. However, the power supply is designed to meet the reliability requirements of various industries, including industrial, medical, and telecommunications. The MTBF can be estimated based on the component failure rates and stress analysis.
