LS-512

CONTROL-LS-512-1/P1

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

FEATURES & FUNCTIONALITY

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 measurement signals, I/O states, flags etc.

The LS-5x2 relays simplify the applications where load bus is served by a mains circuit breaker (MCB) and a generator group breaker (GGB). It senses voltage and current, quantifies the synchronization parameters and transmits the signals via CAN bus to the easYgen-3400XT/3500XT genset controllers. The two breakers control capability along with mains decoupling and protection features make it a perfect choice for transfer switch control under guidance of an external supervisory control. The LS-5x2 is software selectable to be applied as an LS-5x1 thereby facilitating hardware standardization to OEM switchgear builders, generator packagers, and system integrators.

The LS-5x2 Series is available in two different mounting styles. An LS-512 with an aluminum powder coated housing without display is designed to be back panel mounted.
