REC15E-243.3SZ - RECOM Power

REC15E-243.3SZ 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.
• Can I use this module in a high-vibration environment?
  Yes, the REC15E-243.3SZ is designed to withstand high-vibration environments. However, it's essential to ensure that the module is properly secured to the PCB and that the PCB is designed to withstand the vibrations. Additionally, the module's thermal interface material should be suitable for high-vibration applications.
• What is the maximum allowed capacitance for the output filter capacitor?
  The maximum allowed capacitance for the output filter capacitor is 47µF. Exceeding this value may cause instability or oscillation in the module. It's recommended to use a capacitor with a low ESR (Equivalent Series Resistance) to minimize voltage ripple and ensure stable operation.
• Can I use this module in a redundant configuration?
  Yes, the REC15E-243.3SZ can be used in a redundant configuration to achieve high reliability and availability. However, it's essential to ensure that the modules are properly synchronized and that the system is designed to handle the redundancy. RECOM recommends consulting with their application engineers for guidance on redundant configurations.
• What is the recommended input fuse rating?
  The recommended input fuse rating is 2A slow-blow. This ensures that the module is protected from input overcurrent conditions while allowing for normal operation. However, the actual fuse rating may vary depending on the specific application and input voltage.
