Product Overview

The PPU-2 is a modular microprocessor-based generator paralleling and protection controller from DEIF Multi-line 2 series, an end-of-life legacy unit widely used for marine and stationary power systems. It integrates three-phase measurement, automatic synchronisation, load sharing and full generator protection into one panel-mounted controller. It supports standalone running, gen-set parallel operation and grid-parallel modes, managing governor and AVR control to stabilise frequency, active and reactive power. Built with galvanically isolated voltage and current inputs, it prevents measurement distortion and delivers fast fault tripping for reverse power, overcurrent, voltage and frequency deviations. It is commonly sourced as spare part for retrofits, shipboard power plants and backup generator installations.
