Generator Protection Unit

Controller for PLC-based power management systems

DEIF’s Generator Protection Unit (GPU-3) is easy to operate and configure and is the ideal controller for PLC-based power management systems.

The GPU-3 provides comprehensive www.cniacs.com generator protection and synchronization functions. Easily connected to PLCs, SCADA systems, etc. via serial communication.

The unit has all the necessary three-phase measurement circuits and displays all values and alarms on a high quality LCD screen.

The optional Engine Interface Card also features a separate power supply and a separate microprocessor that turns the GPU-3 into an engine control unit with start/stop and protection functions.

and a separate microprocessor. In the event of a GPU3 processor failure, the Engine Interface Card will go into backup mode, ensuring uninterrupted engine monitoring.

monitoring. In the event of a shutdown alarm, the engine automatically shuts down, making it a reliable solution for controlling and monitoring the genset.
