LS-5 Series V2

LS-5 Series V2

    The LS-5×2 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-5×2 is software selectable to be applied as an LS-5×1 thereby facilitating hardware standardization to OEM switchgear builders, generator packagers, and system integrators.

    Woodward’s LS-5 Series are synchronizer controllers with integrated mains decoupling and protection features. The applications range from independent synch check relay to complex power management relay 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 measurement signals, I/O states, flags etc.
