MTR-4P多功能保護繼電器是專為使用作為一個獨立的保護和測量裝置或在單相或三相電力網絡，需要船舶批準大型應用解決方案的組成部分。
DEIF隆重地推出一款**型多功能保護繼電器MTR-4P，它可代替多個單功能保護繼電器。MTR-4P可使用DEIF的特有的PC工具快速進行配置，與傳統解決方案相比，具有成本低廉和靈活性強的特點！ MTR-4P不僅非常適合獨立的保護，也可作為需要船級社認證的單相/三相電網的一部分。
可編程MTR-4P繼電器具有快速、簡單和多功能等特點，可按下述六種不同邏輯類別提供多達 13 種不同的保護功能，六種類別為：電壓、電流、頻率、不對稱性、負載和主電網失電 (LoM)。使用MTR-4P代替 5-10 個單功能保護繼電器可以實現無縫對接！
MTR-4P還可測量和計算50余種參數，例如交流電壓、交流電流、有功/無功視在功率、功率因數、頻率、kWh、kvar、諧波總量、動態和*大需量。MTR-4P配有通用電源，可承受高達1000 V L-L的高交流電壓和高達20 A的電流輸入。
從故障出現到跳閘的通常響應時間小于50ms。因而，MTR-4P可作為改造項目的替代產品，甚至可作為靈活的備件，輕松靈活地安裝在新設備中。調試人員僅需連接一個USB 2.0接口即可快速、輕松配置所有參數和輸出。
MTR-4P的特點：
高達 1,000 V L-L 交流電壓輸入
高達 20 A 交流電流輸入
精度等級：0.5
密碼保護
跳閘時間通常低于 50 ms

13 種不同的保護功能
RS-485 Modbus 通信
通過M-set可輕松、快速地進行調試和設置
19到300 V DC/40 到 276 V AC 通用電源
獲得DNV GL船級社認證
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.
