Technical Specifications Dual identical PCU2000ETH control channels; automatic bumpless failover; 100–480 V AC voltage sensing; 10 A DC excitation output per channel; Ethernet and serial communication; operating temperature: -20°C to +70°C; IP40 enclosure.
Functional Features Dual redundant control; automatic channel failover; bumpless transfer; cross-channel monitoring; common sensing and output interfaces; synchronized configuration.
Application Scenarios Critical power generation facilities, data center generators, hospital standby power, critical process power systems.
Performance Parameters Millisecond-level failover time; zero voltage deviation during transfer; single point of fault tolerance; high system availability.
Material Composition Dual control modules in shared enclosure; redundant power supplies; common sensing transformers; shared output stage.
Structural Characteristics Panel mount enclosure; front channel status indicators; rear common power and signal terminals; dual communication ports.
Working Principle Primary channel performs all control and protection functions while backup channel monitors in parallel. If primary fault is detected, backup takes over control bumplessly to maintain uninterrupted generator operation.
Installation Requirements Mount on control panel; connect common voltage, current and excitation wiring; configure redundant operation parameters; test failover function before commissioning.
