The DEIF PPM-3 SG with DU-2/MKIII is a marine protection and power management controller display unit designed for shaft generator and shore connection applications. It provides monitoring, protection, synchronization, load management, and operator interface functions for marine electrical power systems.

The PPM-3 SG system combines DEIF’s Protection & Power Management technology with the DU-2/MKIII multi-line display, allowing operators to view generator status, electrical measurements, alarms, and operational parameters. It is commonly installed in ship switchboards, engine control rooms, and marine power distribution systems.

This unit is designed for commercial vessels, offshore platforms, and industrial marine power systems requiring reliable generator management and protection functions. The PPM-3 platform is a legacy DEIF product family that is being replaced by newer DEIF iE 350 Marine solutions for new designs.
