1. By using inbuilt device with synchronization,power matching and paralleling functions, the generator set can be synchronized with mains, uninterruptedly returning when reaching the peak. 2. It can parallel up to 32 generator sets as a group. 3. Multiple languages display. 4. Root mean square value voltage measurement. 5. Optional power measurement device. 6. Optional communication ability function, automatic synchronization indication function. 7. Inbuilt or expansion relay outputs.Paralleling switchgear distributes electrical loads across multiple power sources. This improves overall system efficiency, ensuring optimal utilization of available power capacity.Parallel switchgear with synchronous control function.It combines the functions of sets control, monitoring and protection.Parallel switch equipment has simple operation and convenient maintenance.
