8440-2178 LS-5 Series relays are synchronizer controllers

8440-2178

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.
