Woodward’s LS-5 series synchronizer controllers integrate mains decoupling and protection, ranging from simple synch-check relays to complex power management systems. When paired with easYgen-3400XT/3500XT controllers, they minimize wiring by using a single CAN bus for AC signals and I/O data. The LS-5×2 model handles applications with mains and generator breakers by sensing voltage and current, transmitting synchronization parameters via CAN bus, and offering breaker control with mains decoupling. It is software-selectable to function as an LS-5×1, aiding hardware standardization. Key features include controlling up to 32 breakers on 32 bus segments, dedicated application modes, and utility import/export control with approved power measurement. Two mounting options are available: a plastic-housed LS-522 with a graphic LCD for front-door mounting, and an aluminum LS-512 without a display for back-panel mounting.

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.

The LS-5×2 relays simplify the applications where the 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 hard-ware standardization to OEM switchgear builders, generator packagers, and system integrators.

DESCRIPTION

Woodward’s LS-5 Series are synchronizer controllers with integrated mains decoupling and protec-tion features. The applications range from independent synch check relay to complex power man-agement 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 control-lers 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 syn-chronization 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 supervi-sory control. The LS-5x2 is software selectable to be applied as an LS-5x1 thereby facilitating hard-ware standardization to OEM switchgear builders, generator packagers, and system integrators.

The LS-5x2 Series is available in two different mounting styles. An LS-522 with a plastic housing and graphic LCD display is designed to be mounted on the cabinet’s front door. An LS-512 with an aluminum powder coated housing without display is designed to be back panel mounted.
