RAC02-3.3SE/277 - RECOM Power

RAC02-3.3SE/277 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 125°C.
• How do I ensure the module's electromagnetic compatibility (EMC) in my system?
  RECOM recommends following the guidelines in the datasheet for PCB layout, component placement, and shielding to minimize electromagnetic interference (EMI). Additionally, ensure that the system meets the relevant EMC standards, such as EN 55022 and EN 55024.
• What is the derating curve for the module's output power versus ambient temperature?
  The derating curve is typically provided in the datasheet or can be requested from RECOM. As a general guideline, the output power may need to be derated by 1-2% per degree Celsius above 50°C to ensure reliable operation.
• Can I use this module in a redundant or parallel configuration?
  Yes, the RAC02-3.3SE/277 can be used in redundant or parallel configurations, but it's essential to follow RECOM's guidelines for synchronization, current sharing, and fault detection to ensure reliable operation and minimize the risk of damage.
• What is the module's behavior during input voltage brownout or dropout?
  The RAC02-3.3SE/277 has a built-in undervoltage lockout (UVLO) that shuts down the module during input voltage brownout or dropout. The module will automatically restart when the input voltage returns to a safe operating level.
