Easy to operate and configure, DEIF’s Generator Protection Unit (GPU-3) is an ideal controller for PLC-based power management systems. The GPU-3 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. Turning the GPU-3 into an engine control unit featuring start/stop and protection functionalities, the optional engine interface card also has a separate power supply and an independent microprocessor. In cases of GPU3 processor breakdowns, the engine interface card will enter into backup mode and ensure uninterrupted engine supervision. In cases of shutdown alarms, the engine shuts down automatically, making it a reliable solution for the control and supervision of gensets.
