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.
The RAC04-12SA/277 is certified to IEC/EN/UL 62368-1 and meets the requirements for Class II equipment. However, it's essential to ensure that the entire system meets the required safety certifications, and RECOM recommends consulting with a safety expert or testing house for compliance.
RECOM provides a derating curve in the datasheet, which shows the recommended output power reduction as a function of ambient temperature. For example, at 50°C ambient temperature, the output power should be derated by 20% to ensure reliable operation.
Yes, the RAC04-12SA/277 can be used in a redundant or parallel configuration, but it's essential to ensure that the units are synchronized and properly connected to avoid any potential issues. RECOM recommends consulting with their application engineers for guidance on implementing such a configuration.
The RAC04-12SA/277 has a predicted lifespan of 10-15 years, depending on the operating conditions and environment. RECOM provides a reliability report and MTBF (Mean Time Between Failures) data upon request, which can help engineers estimate the converter's reliability in their specific application.
