PEM2-S12-D15-S Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI recommends a PCB layout with a large copper area underneath the module to dissipate heat effectively. A minimum of 1 oz copper thickness is recommended, and the copper area should be connected to a solid ground plane to reduce thermal resistance.
• Can I use this module in a high-vibration environment?
  Yes, the PEM2-S12-D15-S is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in industrial and transportation applications. However, it's essential to ensure proper mounting and screw torque to prevent damage.
• How do I ensure the module's reliability in high-temperature environments?
  To ensure reliability, CUI recommends derating the module's output power by 2.5% per degree Celsius above 40°C. Additionally, ensure good airflow around the module, and consider using a heat sink or thermal interface material to reduce thermal resistance.
• What is the recommended input fuse rating for this module?
  CUI recommends using a fuse with a rating of 2A to 5A, depending on the input voltage and system requirements. The fuse should be able to handle the module's inrush current and provide protection against overcurrent conditions.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PEM2-S12-D15-S can be used in redundant or parallel configurations to achieve higher power output or redundancy. However, it's essential to ensure proper synchronization and control of the modules to prevent damage or instability.
