RECOM recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink or thermal pad to keep the junction temperature below 125°C.
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.
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.
Yes, the RAC03-3.3SE/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.
The RAC03-3.3SE/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.
