RAC04-12DC/230 - RECOM Power

RAC04-12DC/230 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  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 100°C.
• How do I ensure electromagnetic compatibility (EMC) with this converter?
  To ensure EMC, RECOM recommends using a metal enclosure, adding EMI filters, and following proper PCB layout and grounding techniques. Additionally, the converter should be tested according to relevant EMC standards such as EN 55022 and EN 55024.
• What is the maximum allowable capacitance on the output?
  The maximum allowable capacitance on the output is 2200uF. Exceeding this value may affect the stability of the converter.
• Can I use this converter in a redundant or parallel configuration?
  Yes, the RAC04-12DC/230 can be used in a redundant or parallel configuration, but it requires additional external circuitry and careful design consideration to ensure proper operation and fault tolerance.
• What is the typical efficiency of this converter at different loads?
  The typical efficiency of the RAC04-12DC/230 is around 85% at full load, and it decreases to around 75% at 50% load. The efficiency curve can be provided by RECOM upon request.
