Woodward LS-6XT Breaker Controller

Woodward’s LS-5 and LS-6XT breaker controllers deliver accurate synchronization,

integrated mains decoupling, and robust protection features for complex power

management systems. Designed for flexibility, these controllers support diverse applications,

ncluding utility parallel and island operations, with software-configurable options for breaker

control and synchronization. Featuring redundant communication schemes,

intuitive integration with easYgen genset controllers, and rugged housing options,

the LS-5 and LS-6XT ensure reliable and scalable solutions for OEM switchgear builders,

generator packagers, and system integrators.

Additional features available based on the model of the breaker.

LS-6 Breaker Controller

Woodward’s easYgen | LS-6XT control is a 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 system

with multiple utility feeds, bus tie breakers and group breakers in combination with Woodward’s

easYgen-3400XT/3500XT 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 easYgen-3000XT 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. Woodward RP-3000XT is supported over a

separate Ethernet network that works as remote operator control panel.
