Product Overview

PPU2‑GS belongs to DEIF Multi‑Line 2 series, integrated generator synchronizing, load‑sharing and multi‑functional protection unit. It measures generator voltage, current, frequency and power parameters, realizes automatic paralleling for multiple generator sets, and triggers protection trips under abnormal operating conditions. Widely used for marine power‑plant, industrial captive power‑plant and emergency generator control cabinets. Surplus and refurbished tested spare generator control unit for power‑system retrofit and maintenance projects.

Application Notes

‑ Set CT / PT ratio, generator rated parameters before commissioning. ‑ Complete synchronizing and protection secondary injection test after installation. ‑ Typical deployment: Generator paralleling protection controller spare‑part stocking.
