PPU-3 DEIF多线保护和电源管理

 PPU-3  DEIF多线保护和电源管理

DEIF的PPU-3控制和保护装置操作、配置简单，此控制器非常适合基于PLC编程的功率管理系统使用。 除了具有发电机保护和同步功能外，PPU-3还具备负载分配、固定功率、固定频率等控制模式。串口通讯使得与PLC、SCADA系统和其他系统对接更容易。同时也可把PPU-3当成具有起/停和保护功能的发动机控制装置使用，可选发动机接口卡拥有单独的电源和单独的微处理器。 如果PPU-3处理器损坏，发动机接口卡将进入备用模式并确保发动机监测不间断。如果发生停机报警，发动机会自动停机。因此，PPU-3是用于船用机组控制和监测的可靠的解决方案。 利用大量可选功能和可编程逻辑（M-Logic）的应用软件（USW-3），您还可以定制完全符合您要求的控制器。定制特殊功能，根据输入/输出进行逻辑运算等等。一级存储的形式磁存储器，或者磁心存储器,芯绳存储器,薄膜存储器和/或扭转存储器；第三代(例如CRAM克拉姆)或磁卡形式的离线存储；那时，磁带经常被用作二级存储。像闪存和可重写光学介质一样，磁性存储没有明确的重写周期限制，因为改变磁场不会导致物理磨损。相反，它们的寿命受到机械部件的限制

CPU版本7.80及更高版本支持增强的安全性（包括合并的密码表）。这提供了一种更安全的机制来设置和验证密码和OEM密钥，而不是传统安全模式。有关CPU型号，请参阅重要产品信息文档以及您正在使用的固件版本。有关增强的安全性操作，请参阅增强的密码安全性和OEM保护。A.增强型和传统型安全模式之间的操作差异摘要见传统/增强安全性比较。

DEIF's PPU-3 control and protection device is simple to operate and configure, and this controller is very suitable for power management system based on PLC programming. In addition to generator protection and synchronization functions, PPU-3 also has control modes such as load distribution, fixed power and fixed frequency. Serial communication makes it easier to interface with PLC, SCADA system and other systems. At the same time, PPU-3 can also be used as an engine control device with start/stop and protection functions. The optional engine interface card has a separate power supply and a separate microprocessor. If the PPU-3 processor is damaged, the engine interface card will enter standby mode and ensure uninterrupted engine monitoring. If a shutdown alarm occurs, the engine will automatically stop. Therefore, PPU-3 is a reliable solution for marine unit control and monitoring. With a large number of optional functions and M-Logic application software (USW-3), you can also customize the controller that fully meets your requirements. Customize special functions, perform logical operations according to input/output, and so on.

Magnetic memory in the form of primary storage, or magnetic core memory, core rope memory, thin film memory and/or torsion memory; Third generation (such as CRAM Cram) or offline storage in the form of magnetic card; At that time, magnetic tape was often used as secondary storage. Like flash memory and rewritable optical media, magnetic storage has no definite rewriting period limit, because changing the magnetic field will not lead to physical wear. On the contrary, their life is limited by mechanical parts.

CPU version 7.80 and later support enhanced security (including merged password tables). This provides a more secure mechanism to set and verify passwords and OEM keys, instead of the traditional security mode. For the CPU model, please refer to the important product information documents and the firmware version you are using. For enhanced security operations, see Enhanced Password Security and OEM Protection. A see comparison of traditional/enhanced security for a summary of operational differences between enhanced and traditional security modes.
