Manufacturer product number: 8440-2180

Description: Woodward: CONTROL-LS-511-1/P1 V2. 1A, Circuit Breaker Control & Protection

Predecessor: 8440-1951

Woodward’s LS-5 Series relays are synchronizer controllers with integrated mains de

coupling and protection features. The applications range from independent synch check

relay to complex power management with multiple utility feeds, bus tie-breakers and

group breakers in combination with Woodward’s easYgen-3400XT/3500XT equipped

genset controllers. Wiring efforts are reduced to a minimum, since only one CAN bus

connection is required between all LS-5 and easYgen controllers to transmit AC meas

urement signals, I/O states, flags, etc.

The LS-5×1 devices manage synchronization, loading and un-loading on each bus seg

ment and send the required voltage, frequency and phase angle references via CAN bus

to the easYgen-3400XT/3500XT genset controllers. When serving an incoming mains

breaker it automatically detects mains failure, performs mains decoupling and sends the

start signal to the easYgen. The LS-5×1 is software selectable to be applied as an inde

pendent synch check relay, mains circuit breaker control or bus tie-breaker control

thereby providing exceptional versatility and value for OEM switchgear builders, genera

tor packagers, and system integrators.

The LS-5×1 Series is available in two different mounting styles. An LS-521 with a plastic

housing and graphic LCD display is designed to be mounted on the cabinet’s front door.

An LS-511 with an aluminum powder coated housing without display is designed to be

back panel mounted.
