MORNSUN recommends a 4-layer PCB with a solid ground plane and a separate layer for the input and output voltage rails. This helps to reduce EMI and improve thermal performance.
MORNSUN recommends derating the output power by 2.5% per degree Celsius above 40°C to ensure reliable operation. Additionally, ensure good airflow and thermal management around the module.
MORNSUN recommends a maximum output capacitance of 220uF to prevent oscillation and ensure stable operation. Exceeding this value may lead to instability or damage to the module.
Yes, the QAW02 can be used in redundant or parallel configurations, but MORNSUN recommends using a dedicated ORing diode or redundancy module to ensure reliable operation and prevent back-feeding.
MORNSUN estimates the MTBF of the QAW02 to be around 1.5 million hours, based on MIL-HDBK-217F calculations. However, this value may vary depending on the specific application and operating conditions.
