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. 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-5×1 devices manage synchronization, loading and un-loading on each bus segment and send the required voltage, frequency and phase angle references via CAN bus to the easYgen-3400XT/3500XT genset controllers. When serving an incoming mains breaker it automatically detects mains failure, performs mains decoupling and sends the start signal to the easYgen. The LS-5×1 is software selectable to be applied as an independent synch check relay, mains circuit breaker control or bus tie-breaker control thereby providing exceptional versatility and value for OEM switchgear builders, generator packagers, and system integrators.
Microprocessor-based synchronizers designed for use on two or three phase AC generators equipped with speed controls and automatic voltage regulators.
DSLC-2 synchronizes and controls the generator loading for up to 32 three phase AC generators using the integrated Ethernet communication network.
