Multi-breaker control LS-612 XT P2
NEW
Woodward’s easYgen | LS-6XT control is synchronizer controller with integrated mains decoupling and protection features. It enables several redundant communication schemes with peer controls. The applications range from independent synch check relay to complex power management sys-tem with multiple utility feeds, bus tie breakers and group breakers in combination with Kuhse KEA 350 equipped genset controllers and/or easYgen | GC-3400XT equipped genset groups.
Redundant busses running among the peer controls ensure that availability of your power generation asset is not compromised to a single point of failure. The LS-6XT control together with KEA 350 controls are designed to support OEM switch-gear builders, generator packagers, and system integrators standardize on a single hardware for a multitude of utility parallel or island operations.
Off-the-shelf LS-6XT control is software configurable for one/two breaker control, gensets / genset groups handling, and stand-alone/multi-unit application.
The LS-6XT controller is available in a rugged aluminum powder coated housing. An LED Annunciator plate is integrated to the front for local annunciation of alarms that are customizable on-site. Kuhse RP300 is supported over a separate Ethernet network that works as remote operator control panel.
