伍德沃德的LS-5系列继电器是同步器控制器集成电源去耦和保护功能。应用范围从独立的同步检查继电器到复杂的电源管理与多个公用事业馈电，总线连接断路器和

LS-5系列是具有集成保护功能的同步器和负载共享控制器。它们旨在实现复杂的电源管理应用，具有多个输入电源和母线断路器，并结合配备easYgen-3400/3500的发电机组控制器。

8440-2178 LS-5设备将管理每个总线段的同步、加载和卸载，并通过CAN总线将所需的电压和频率参考发送到easYgen-3400/3500发电机组控制器。LS-5装置位于输入电源断路器上，将自动检测电源故障并相应地启动相应的发电机组。布线工作减少到最低限度，因为在所有LS-5和easYgen-3400/3500控制器之间只需要一个CAN总线连接。不需要在LS-5和easYgen-3400/3500控制器之间连接任何交流测量信号或离散输入/输出。

8440-2178通过离散输入或接口提供广泛的远程控制功能，可以轻松将LS-5集成到每个应用环境中。

后面板安装LS-521具有坚固的铝制底盘，适用于恶劣环境或密闭空间。

8440-2178 功能包括:

多达16个LS-5单元可以与多达32个easYgen-3400/3500在一个网络中运行

相位匹配或滑移频率同步与电压匹配

全保护包(包括df/dt (ROCOF)，相移和电源电压增加保护，符合新的德国电网规范VDE-0126-1-1的要求)

分段控制的负荷分担

事件日志，最多300个条目

LS-5单元和连接的easYgen-3400/3500控件之间的自动日期和时间同步

LS-5“独立”模式没有easYgen-3400/3500是可能的

现场最常见应用(MCB或MCB/GGB应用)的预配置应用模式

自动和手动模式

全远程控制通过CAN或RS-485接口

如果在应用中使用变压器，矢量组调整是可用的

断路器开/关故障检测

Woodward's LS-5 series relays are synchronizer controllers with integrated power decoupling and protection functions. Applications range from standalone sync check relays to complex power management with multiple utility feeds, bus connections and circuit breakers

The LS-5 series is a synchronizer and load sharing controller with integrated protection. Designed for complex power management applications, they feature multiple input power supplies and bus circuit breakers combined with generator set controllers equipped with the easYgen-3400/3500.

The 8440-2178 LS-5 device will manage the synchronization, loading and unloading of each bus segment and send the required voltage and frequency reference to the easYgen-3400/3500 generator set controller via the CAN bus. The LS-5 device is located on the input power circuit breaker and will automatically detect the power failure and start the corresponding generator set accordingly. Cabling work is reduced to a minimum as only one CAN bus connection is required between all LS-5 and easYgen-3400/3500 controllers. There is no need to connect any AC measurement signals or discrete inputs/outputs between the LS-5 and the easYgen-3400/3500 controller.

The 8440-2178 provides a wide range of remote control capabilities via discrete inputs or interfaces, making it easy to integrate the LS-5 into every application environment.

The rear panel mount LS-521 has a rugged aluminum chassis for use in harsh environments or confined Spaces.

8440-2178 Features include:

Up to 16 LS-5 units can operate in a network with up to 32 easYgen-3400/3500

Phase matching or slip frequency synchronization with voltage matching

Full protection package (including df/dt (ROCOF), phase shift and supply voltage increase protection, as required by the new German Grid specification VDE-0126-1-1)

Load sharing with segmented control

Event log, up to 300 entries

Automatic date and time synchronization between LS-5 units and connected easYgen-3400/3500 controls

The LS-5 "standalone" mode is possible without the easYgen-3400/3500

Pre-configured application mode for the most common applications in the field (MCB or MCB/GGB applications)

Automatic and manual modes

Full remote control via CAN or RS-485 interface

If a transformer is used in the application, vector group adjustment is available

Circuit breaker on/off fault detection

Mains decoupling "test" mode

Multilingual function

Keyboard lock function
