RAC20-05SN - RECOM Power

RAC20-05SN Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM recommends a PCB layout with a large copper area connected to the module's thermal pad to ensure good heat dissipation. A minimum of 1 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 RAC20-05SN is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in industrial and transportation applications. However, it's recommended to follow proper mounting and screw torque procedures to ensure the module remains securely attached to the PCB.
• How do I ensure the module's input voltage stays within the recommended range?
  Use a suitable input voltage regulator or a voltage stabilizer to ensure the input voltage stays within the recommended range of 18-32V. Additionally, consider adding input voltage monitoring and protection circuits to prevent damage from voltage spikes or dips.
• What is the recommended fuse rating for overcurrent protection?
  RECOM recommends using a fuse with a rating of 2-3A, depending on the specific application and load requirements. The fuse should be able to handle the module's maximum output current and provide adequate protection against overcurrent conditions.
• Can I parallel multiple RAC20-05SN modules to increase output power?
  Yes, it is possible to parallel multiple RAC20-05SN modules to increase output power. However, it's essential to ensure that the modules are properly synchronized and that the output voltage is matched to prevent uneven current sharing. RECOM recommends consulting their application notes and seeking guidance from their technical support team for proper implementation.
