Multi-breaker control LS-521

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 Kuhse KEA 350 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-5x1 units manage synchronization as well as load and unload on each busbar segment and send the required values for voltage, frequency and phase angle to the KEA 350 genset controllers via CAN bus. If the unit acts as an incoming mains circuit breaker, it automatically detects mains failures, performs mains decoupling and sends the start signal to the KEA 350. The LS-5x1 can be selected via software for use as an independent synchro relay, mains circuit breaker or busbar coupling switch. As a result, it offers exceptional versatility and provides unparalleled value to switchgear and generator package providers as well as system integrators.

The LS-5x1 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.
