The GPC 300 controller is a highly configurable controller that can be customised to many different applications. It contains the functions required to protect and control a diesel generator, mains connection, or bus tie breaker, and their associated breakers. 

You can reconfigure the onboard software for all of these applications, for example to change a genset controller to a mains connection controller, using the PICUS software utility. This makes the GPC 300 controller a very flexible building block in your power system. 

If you need extended controller functionality, you can order the GPC 300 controller with a CODESYS PLC environment.  

Part of the versatile GPC 300 range 

The GPC 300 controller is versatile controller with built-in load sharing and synchronisation features. It can be used for a wide range of marine and offshore applications with an extensive range of protection, supervision, and control functions. The GPC 300 can be used in a power management solution where the power management logic is located elsewhere, and it handles busbar sections with ease. The power management can then either be customer built via CODESYS PLC or via an external PLC 

Highly customisable architecture 

All GPC 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. In addition, you can add up to 9 expansion racks to a single GPC 300 to get up to 58 free module slots (up to 4 in the base rack and up to 6 in each expansion rack). 

Unique ANSI 87G differential protection 

With the optional 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.
