RS3-1209S - RECOM Power

RS3-1209S 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 2 oz copper thickness is recommended, and the copper area should be connected to a heat sink or a metal plate for further heat dissipation.
• How do I ensure the module's reliability in high-temperature environments?
  To ensure reliability in high-temperature environments, RECOM recommends following the derating curves provided in the datasheet, using a suitable heat sink, and ensuring good airflow around the module. Additionally, the module should be operated within the recommended temperature range and the input voltage should be kept within the specified limits.
• What is the recommended input capacitor type and value for this module?
  RECOM recommends using a low-ESR ceramic capacitor with a value of 10-22uF, X7R or X5R dielectric, and a voltage rating of 50V or higher. The capacitor should be placed as close as possible to the module's input pins to minimize noise and ensure stable operation.
• Can I use this module in a redundant or parallel configuration?
  Yes, the RS3-1209S can be used in a redundant or parallel configuration, but RECOM recommends following specific guidelines to ensure reliable operation. Please consult RECOM's application notes or contact their technical support for more information.
• What is the module's behavior during input voltage brownout or dropout?
  The RS3-1209S is designed to shut down during input voltage brownout or dropout to prevent damage to the module or the load. The module will automatically restart when the input voltage returns to a safe operating level.
