RAC04-3.3SK/277 Frequently Asked Questions (FAQs)

  • RECOM recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the junction temperature below 125°C.
  • The RAC04-3.3SK/277 is certified to IEC/EN/UL 62368-1 and meets the requirements for IT and industrial applications. However, it's essential to ensure that the converter is used within its specified operating conditions and that the system design meets the relevant safety standards.
  • The recommended maximum output capacitance is 220uF to ensure stable operation. Exceeding this value may lead to oscillations or instability in the converter.
  • Yes, the RAC04-3.3SK/277 can be used in a redundant or parallel configuration, but it's essential to ensure that the converters are synchronized and that the system design takes into account the increased power rating and thermal management requirements.
  • The typical efficiency of the RAC04-3.3SK/277 is around 84% at full load, and it varies with load. The efficiency curve can be obtained from RECOM or through characterization during the design process.
