Protection and Power Management, PPM 300

DEIF is proud to announce its latest paradigm shift in Protection and Power Management Systems; PPM 300.  The PPM 300 follows its predecessor systems by being a highly versatile controller designed for the stringent demands of marine use.   It is capable of meeting the requirements for a wide range of control, protection and supervision applications.  Applications range from simple genset control and protection, to fully integrated and engineered power management solutions, developed for fuel-efficient operation.   Each controller contains all the functions that are needed to protect and control diesel generators (including an emergency diesel generator), shaft generator, shore connection, or bus tie breakers.   Together, the PPM 300 controllers create one integrated system solution.   The power management system controls the entire vessel’s electrical power production ensuring that the power required is always available and reliable. The power management system also ensures optimum performance in terms of stable operation and fuel economy.   The PPM 300 controllers work together as a multi-master system with redundant communication. This means that no single controller functions as the master controller.  If the generator set controlled by the master system is being repaired or the master control has issues, the master controller function moves to the next prioritized system, keeping the system safe and reliable.   The controller includes the most current processor technology and high-speed internal communication. It provides fast protection functions and includes built-in redundancy, for greater reliability. The modular design enables the controller to automatically recognize an additional or substitute processor, communication, measurement and input-output modules.   The controller’s display unit includes a color graphic screen and intuitive sequences for fast readout of live data, and easy access to alarms and parameters.  All engine, generator and power system critical data is easy to read. The user interface adapts according to the user, for easy and safe controller operation. The light indicators of the display unit are visible over a long distance. The display processor can handle all languages with UTF-8 fonts.
