Woodward|8440-2150A|LS-521 Circuit Breaker Control Module
WOODWARD LS-521 Circuit Breaker Control Module
Description
WOODWARD LS-521 is a compact synchronizer and protection relay with integrated circuit breaker control, designed for complex power management applications, supporting automatic synchronization, mains decoupling, and protection functions.
Features
Supports up to 16 LS-5 units and 32 bus segments in one network. Enables synch check, vector group adjustment, utility import/export control, and standalone operation without easYgen-3400XT/3500XT. Offers LogicsManager customization, CAN and RS-485 interfaces, true RMS sensing, and configurable relay outputs and discrete inputs. Complies with RoHS2, BDEW, and VDE AR-N 4105.
