2. N+1 Redundancy Parallel, No Disturbance Switching

It supports N+1 redundant parallel configuration. Multiple power modules of the same model can be synchronized and parallel-operated, automatically distributing the load. When a single module fails, the remaining modules automatically take over all the loads seamlessly, with a switching process without voltage fluctuations or system disturbances. The switching time is in the millisecond range, completely eliminating the risk of system shutdown due to power supply failure. The module is equipped with high-precision current sharing circuits, and the load distribution error during parallel operation is less than 5%, avoiding overloading of a single module, extending the overall service life, meeting SIL 3 level safety requirements, and suitable for high-safety-level industrial scenarios.
