The maximum capacitive load is not explicitly stated in the datasheet, but as a general rule, RECOM recommends limiting the output capacitance to 10-20 times the output capacitance of the converter itself, which is 100nF. Therefore, the maximum capacitive load would be around 1-2uF.
To ensure the converter operates within its specified temperature range, make sure to provide adequate airflow, avoid blocking the airflow vents, and keep the ambient temperature within the specified range of -40°C to +85°C. Additionally, consider derating the output power at high temperatures to prevent overheating.
While the R1S-3.305/H-R is designed to be rugged, it's essential to ensure the converter is properly secured to the PCB or chassis to prevent damage from vibration. RECOM recommends following the recommended mounting and soldering guidelines to ensure reliable operation in high-vibration environments.
The recommended input fuse rating is not explicitly stated in the datasheet, but as a general rule, RECOM recommends using a fuse with a rating of 1-2 times the maximum input current, which is 1.5A for the R1S-3.305/H-R. Therefore, a 2-3A fuse would be a suitable choice.
While it's technically possible to parallel multiple converters, it's not recommended as it can lead to uneven current sharing, reduced reliability, and increased complexity. Instead, consider using a single higher-power converter or consulting with RECOM's application engineers for custom solutions.
