Description: woodward: LS-512-5 V2. 5A, Multibreaker Control for complex power management applications

Multi-Breaker

Control for

complex power management applications

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-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 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-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.

The LS-5×2 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.
