WRA4815S-3WR2 Frequently Asked Questions (FAQs)

MORNSUN recommends a PCB layout with a large copper area connected to the GND pin for heat dissipation. A minimum of 1 square inch of copper area is recommended. Additionally, it is recommended to use thermal vias to connect the copper area to the internal layers of the PCB.
To ensure reliability in high-temperature environments, it is recommended to derate the output power of the module according to the temperature derating curve provided in the datasheet. Additionally, ensure good airflow around the module and use a heat sink if necessary.
MORNSUN recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The capacitor should be placed as close to the VIN pin as possible to minimize noise and ensure stable operation.
Yes, the WRA4815S-3WR2 can be used in a redundant power supply configuration. However, it is recommended to use a diode or a switch to isolate the outputs of the two modules to prevent back-feeding and ensure reliable operation.
The maximum allowable voltage deviation on the input voltage is ±10% of the nominal input voltage. Exceeding this deviation may affect the reliability and performance of the module.
