PPU-3 DEIF paralleling & protection unit (PPU)

Easy to operate and configure, DEIF's PPU-3 control and protection unit is an ideal

controller for PLC-based power management systems.

Apart from generator protection and synchronisation, the PPU-3 also features

regulation modes including load sharing, fixed power, fixed frequency, etc. Serial

communication enables easy interfacing with PLCs,SCADA-systems and more, and

the unit features all necessary three-phase measuring circuits, displaying all values

and alarms on a quality LCD screen.

Turning the PPU-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 PPU-3 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 control and supervision of marine gensets.
