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-5×2 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 synchronization 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 supervisory control. The LS-5×2 is software selectable to be applied as an LS-5×1 thereby facilitating hardware 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.
