MTR-4P多功能保护继电器是专为使用作为一个独立的保护和测量装置或在单相或三相电力网络，需要船舶批准大型应用解决方案的组成部分。
DEIF隆重地推出一款**型多功能保护继电器MTR-4P，它可代替多个单功能保护继电器。MTR-4P可使用DEIF的特有的PC工具快速进行配置，与传统解决方案相比，具有成本低廉和灵活性强的特点！ MTR-4P不仅非常适合独立的保护，也可作为需要船级社认证的单相/三相电网的一部分。
可编程MTR-4P继电器具有快速、简单和多功能等特点，可按下述六种不同逻辑类别提供多达 13 种不同的保护功能，六种类别为：电压、电流、频率、不对称性、负载和主电网失电 (LoM)。使用MTR-4P代替 5-10 个单功能保护继电器可以实现无缝对接！
MTR-4P还可测量和计算50余种参数，例如交流电压、交流电流、有功/无功视在功率、功率因数、频率、kWh、kvar、谐波总量、动态和*大需量。MTR-4P配有通用电源，可承受高达1000 V L-L的高交流电压和高达20 A的电流输入。
从故障出现到跳闸的通常响应时间小于50ms。因而，MTR-4P可作为改造项目的替代产品，甚至可作为灵活的备件，轻松灵活地安装在新设备中。调试人员仅需连接一个USB 2.0接口即可快速、轻松配置所有参数和输出。
MTR-4P的特点：
高达 1,000 V L-L 交流电压输入
高达 20 A 交流电流输入
精度等级：0.5
密码保护
跳闸时间通常低于 50 ms
二级跳闸设置
启动延时
13 种不同的保护功能
RS-485 Modbus 通信
通过M-set可轻松、快速地进行调试和设置
19到300 V DC/40 到 276 V AC 通用电源
获得DNV GL船级社认证
Fast, simple and multi-functional, the programmable MTR-4P protection relay offers up to 13 different protection functions in six different logical categories: Voltage, current, frequency, asymmetry, load and loss of Mains (LoM). Simultaneously, the MTR-4P can be used as a dedicated measuring point reachable by communication and capable of measuring and calculating more than 50 parameters such as AC voltage, AC current, active/reactive apparent power, power factor, frequency, kWh, kvar, THD, dynamic and maximum demands.
MTR-4P is designed for use as a stand-alone protection and measuring unit or as component in large application solutions on single-phase or three-phase electrical power networks that require marine approval.
Featuring a universal power supply, the MTR-4P withstands high AC voltage inputs of up to 1000 V L-L and currents of up to 20 A. The typical response time less than 50 ms, from error occurs to trip. This makes the MTR-4P flexible and easy to install in new buildings, as replacement in retrofit projects, or even as a flexible spare part. Simply connect a USB 2.0 interface for fast and easy configuration of all setting parameters and outputs.
