R1D-243.3/HP Frequently Asked Questions (FAQs)
RECOM recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module is also recommended.
To ensure reliable start-up, RECOM recommends a soft-start circuit or a ramp-up circuit to limit the inrush current. Additionally, a thermistor or thermocouple can be used to monitor the temperature and delay start-up until the module has reached a safe operating temperature.
RECOM recommends a fuse rating of 5A to 10A, depending on the input voltage and current requirements. The fuse should be sized to protect the module from overcurrent conditions.
Yes, the R1D-243.3/HP can be used in a redundant or parallel configuration to achieve higher power or redundancy. However, RECOM recommends consulting with their application engineers to ensure proper design and implementation.
According to RECOM, the typical MTBF for the R1D-243.3/HP is >1 million hours, calculated according to MIL-HDBK-217F.
