Product Overview

Woodward’s LS-5 Series relays are synchronizer controllers with integrated mains decoupling and protection features.

Key Features

✓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
✓Full protection package ( including df/dt (ROCOF), phase shift and mains voltage increasing protection according to new German grid code requirements in VDE-0126-1-1)
✓Segment control for the load sharing
✓Event Log with up to 300 entries
✓Automatic date and time synchronization between the LS-5 units and the connected easYgen-3400/3500 controls
✓LS-5 “Stand alone” mode without the easYgen-3400/3500 is possible
✓Preconfigured application modes for the most common applications in the field (MCB or MCB/GGB application)
✓Automatic and Manual mode
✓Full remote control via CAN or RS-485 interface
✓In case transformers are used in the application, vector group adjustment is available
✓Breaker open/close failure detection
✓Mains decoupling “Test” mode
✓Multilingual capability
✓Lock Keypad feature
✓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.
✓The Woodward LS-5 Series are synchronizer and load share 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 unloading 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 incoming mains breakers will automatically detect mains failures and start the corresponding 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 controllers.
✓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 back panel mounted LS-521 has a rugged aluminum chassis for use in harsh environments or confined spaces.
