DEIF PPU/2/GS 100066899.70 Generator Parallel Protection Unit

Product Description

DEIF PPU/2/GS (Part No.: 100066899.70) is a generator paralleling and protection unit of the Multi-line 2 series. It is an all‑in‑one microprocessor‑based controller for synchronisation, regulation and protection. This model is end‑of‑life and only available as spare replacement part. It integrates synchronising, power control, load sharing and comprehensive electrical protection. It adopts 3-phase true RMS measurement, galvanically isolated AC inputs, programmable relay outputs and supports multiple operation modes. Configuration is done via DEIF PC utility software for genset paralleling and fault protection.
