How to prevent transmission interruption when the voltage drops in the power DTU?

Ensuring uninterrupted transmission during voltage dips requires power redundancy and software fault tolerance. This is achieved by employing a wide-voltage input power module, ranging from 85-265VAC, and adding a large-capacity capacitor (e.g., 10000μF) for energy storage on the DC side. A UPS or supercapacitor backup is deployed to maintain power supply in case of mains failure. On the software side, a connection retention mechanism is added for rapid reconnection after a brief disconnection. Testing simulates a voltage drop of 50% for 10ms; the system should maintain connection. Voltage dip immunity design ensures stable operation during grid fluctuations, improving availability.
