Detail LS 5
The LS-5 Series are synchronizer controllers with integrated protective functions. They are designed to enable complex power management applications with multiple incoming mains and bus breakers in combination with easYgen-3400/ 3500 equipped genset controllers.
The LS-5 devices will manage synchronization, loading and un-loading on each bus segment and send the required voltage and frequency references via CAN bus to the easYgen-3400/ 3500 genset controllers. LS-5 devices which are located on the incom-ing mains breakers will automatically detect mains failures and start the correspond-ing gensets accordingly. Wiring efforts are reduced to a minimum, since only one CAN bus connection is required between all LS-5 and easYgen-3400/ 3500 control-lers. It is not required to wire any AC measurement signals or discrete inputs/ outputs between the LS-5 and easYgen-3400/ 3500 controllers.
Extensive remote control capabilities via discrete inputs or interfaces are provided to easily integrate the LS-5 into each application environment.
The LS-5 Series is available in two different housing versions. The LS-521 with a plastic housing and graphic LCD display is designed to be mounted on the cabinet’ s front door. The LS-511 with an aluminum powder coated housing without display is designed to be back panel DIN Rail mounted.
• Up to 16 LS-5 units can be operated in one network with up to 32 easYgen-3400/ 3500
• Phase match or slip frequency synchronization with voltage matching
