R-745.0D - RECOM Power

R-745.0D 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 derating the output power according to the temperature derating curve provided in the datasheet. Additionally, ensuring good airflow and heat dissipation around the module is crucial. It's also important to follow proper storage and handling procedures to prevent damage to the module.
• What is the recommended input capacitor type and value for this module?
  RECOM recommends using a low-ESR ceramic capacitor with a value of 10-22 μF and a voltage rating of at least 50 V. The capacitor should be placed as close as possible to the input pins of the module to minimize noise and ripple.
• Can I use this module in a redundant or parallel configuration?
  Yes, the R-745.0D can be used in a redundant or parallel configuration, but it's essential to follow RECOM's guidelines for parallel operation. This includes using identical modules, ensuring proper synchronization, and implementing a suitable current sharing mechanism.
• What is the typical start-up time for this module?
  The typical start-up time for the R-745.0D is around 10-20 ms, depending on the input voltage and output load. However, this time can vary depending on the specific application and system design.
