PPM 300



The robust and reliable PPM 300 is a versatile controller with built-in power management features that can be used for a wide range of marine and offshore applications –from generator control and protection to engineered power management solutions developed for diesel generators (including emergency generators), shaft generators, battery energy storage, shore connections, and bus tie breakers. For a complete list of PPM 300 approvals and certifications, see the Documentation tab.

Eradicating single points of failure with power management

With several PPM 300 controllers, you can design a multi-master power management solution which ensures that the required power is always present and optimises fuel consumption. The multi-master architecture eradicates single points of failure: If a controller fails, master functionality is automatically moved to another controller, keeping the system not just operational but safe and reliable at all times.

PPM 300 variants

The PPM 300 is available in the following variants. Each variant can be further customised to your application by selecting the required modules and configuring the controller software; for more information, see below.

Customisable architecture

All PPM 300 variants can be specified with 4 or 7 I/O module slots. The modules provide voltage and current measurement, I/O, engine control, governor and AVR functions, and communication. Three modules are mandatory, but you can use the remaining 1 or 4 slots to customise the controller by adding modules or leave them empty. For a full list of modules, see the Modules tab. For lists of recommended modules, see the variant descriptions.

Unique ANSI 87G differential protection

With the ACM3.2 module, you can add ANSI 87G differential protection for generators. The module measures phase currents on the consumer and neutral sides of a generator in order to detect phase-to-phase faults or phase-to-earth faults in earthed generator systems. With this unique feature, you can design reliable and safe power systems without external differential protection devices.

Extensive expansion options

You can add up to 9 expansion racks to a single PPM 300 to get up to 58 free module slots (up to 4 in the base rack and up to 6 in each expansion rack). You can connect up to 32 controllers on a DEIF network. Modules can easily be added or replaced in the field, and new modules are automatically recognised by the controller.

Quick setup using PICUS and CustomLogic

You can quickly configure your PPM 300 using our free PICUS PC software utility which includes the user-friendly CustomLogic tool. The software allows you to carry out complex plant designs, for example applications with several busbars or multiple ring connections, and you can easily access design documentation and carry out commissioning.

Easy system integration with Flexible Modbus

The built-in Flexible Modbus functionality of the PPM 300 allows you to customise its Modbus addresses to match your master controller configuration. Using PICUS, you can easily duplicate the default Modbus table of your PPM 300 and edit or move the functions located at given addresses, making it much easier to install the PPM 300 in an existing system.

User-friendly 5” colour display

The 5” colour graphic display has intuitive sequences and icons for fast readout of live data. You have easy access to alarm handling and controller setup, and functionality is defined and targeted according to user permission levels.
