The LS-511/521 Marine is designed to enable complex power management applications with multiple segments and bus breakers in combination with easYgen™-3400/3500 equipped genset controllers. The LS-5 devices manage synchronization, loading and unloading on each bus segment, and send the required voltage and frequency references via CAN bus to the easYgen-3400/3500 genset controllers. Wiring efforts are reduced to a minimum, since only one CAN bus connection is required between all LS-5 and easYgen-3400/3500 controllers. It is not required to wire any AC measurement signals or discrete inputs/outputs between the LS-5 and easYgen controllers. The LS-5 can also be used as a sync-check relay in stand-alone mode without easYgens.
Equipped with redundant monitoring of circuit breaker, LS-5 Marine controllers together with easYgen-3400/3500 Marine controllers enable you to command from simple to the most complex electrical power systems in your marine application.
