RLS-397-R - RECOM Power

RLS-397-R Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM Power Inc 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 the RLS-397-R in a high-vibration environment?
  Yes, the RLS-397-R is designed to withstand vibrations up to 10G peak acceleration, making it suitable for use in high-vibration environments. 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 applications?
  To ensure reliability in high-temperature applications, it's crucial to maintain a maximum junction temperature of 125°C. This can be achieved by providing adequate airflow, using a heat sink, and ensuring proper thermal management.
• What is the recommended input capacitor type and value for the RLS-397-R?
  RECOM Power Inc recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, rated for the input voltage, to ensure stable operation and minimize input ripple.
• Can I parallel multiple RLS-397-R modules to increase the output current?
  Yes, you can parallel multiple RLS-397-R modules to increase the output current. However, it's essential to ensure that each module has its own input capacitor and that the modules are properly synchronized to prevent oscillations.
