Easy to operate and configure, DEIF’s Generator protection unit (GPU-3 hydro) is an ideal controller for PLC-based hydro power systems.
The GPU-3 hydro offers comprehensive generator protection and synchronization. Serial communication enables easy interfacing with PLCs, SCADA systems and more, and the unit features all necessary 3-phase measuring circuits and displays all values and alarms on a quality LCD screen.
For start/stop and protection functionalities, add the GPU-3 hydro turbine control option, a turbine interface card with separate power supply and independent microprocessor. In cases of GPU-3 hydro main processor failure, the engine interface card will activate its back-up mode to ensure uninterrupted turbine supervision and automatic turbine shutdown in case of shutdown alarm.
With free software download and upgrade at www.deif.com, it is possible to customize the application to suit your needs exactly: dedicate specific functions or logic conditions to different inputs and outputs and tune all sequences according to your requirements.
