EAP-20-472 - Cosel

EAP-20-472 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Cosel recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure efficient heat dissipation. A minimum of 2 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
• Can I use this module in a high-vibration environment?
  Yes, the EAP-20-472 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, Cosel 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?
  Cosel recommends using a fuse with a rating of 2A to 5A, depending on the specific application and input voltage. The fuse should be able to handle the module's peak inrush current, which is typically around 10A to 15A.
• Can I use this module in a redundant or parallel configuration?
  Yes, the EAP-20-472 can be used in redundant or parallel configurations to achieve higher power output or redundancy. However, it's essential to ensure proper synchronization and ORing diode implementation to prevent damage or instability.
