Description
The LS-5 8440-1946 is a synchronizer controller in the LS-5 series. The LS-5 series devices are synchronizer controllers with integrated protection functions. They are designed to enable complex power management applications with multiple breakers on incoming lines and buses, and in conjunction with generator controllers equipped with the easYgen-3400/3500 system.
Applications
Shipbuilding Plants: Manages generator paralleling under marine classification standards.
Thermal Power Plants: Synchronizes turbine generators under high-voltage conditions.
Petrochemical Plants: Protects control paths using isolated relay and input systems.
Emergency Power Plants: Enables fast breaker closure for critical backup systems.
Industrial Power Plants: Withstands moisture in washdown control panels.
Function
Up to 16 LS-5 devices and up to 32 easYgen-3400/3500 devices can operate in a single network.
Synchronization of phase or slip frequency matching with voltage matching.
Full protection package (including df/dt (ROCOF) protection, phase shift protection, and supply voltage surge protection, compliant with the requirements of the new German VDE-0126-1-1 network operating and maintenance manual).
Segment control for load distribution.
