Main Features and Advantages
Let’s get into what makes the DEIF PPU/2/GS a core piece of kit in your control lineup.
First off,it’s a full-blown protection and paralleling unit packed into one.Synchronization?Check.Generator control?Check.Load-sharing and reverse power cut-off?Double check.This is no-waste engineering,combining what others spread into several modules.
The galvanically separated three-phase measurement is a fortress against noise and interference—vital when you’re on a choppy sea or managing high-power sources.Then you’ve got reverse-power protection(ANSI 32)built-in,protecting your generator from dangerous backflow without extra modules.
Navigating settings is slick:flip through parameters on the built-in LCD or handle tuning via RS-232 using DEIF’s Windows utility.Easy,secure,and quick—no wrestling with cryptic LEDs or guesswork.In harsh environments,reliability matters.Rugged design,marine-grade spec,and smart packaging in the Multi-Line 2 format make the DEIF PPU/2/GS a stalwart operator.
All in all,if you’re running multiple generators or linking to grid power,the DEIF PPU/2/GS ensures smooth operation,quick recovery from faults,and minimal system complexity.It’s your dependable automation backbone—clear,precise,and built to last.
Application Field
Here’s where the DEIF PPU/2/GS really earns its stripes:
In marine power systems,especially on hybrids and multi-gen ships,the DEIF PPU/2/GS excels in managing synchronization,load sharing,and electrical protection.It keeps your propulsion and auxiliary power smooth even when the sea’s tossing the boat.
Industrial power houses or data center backup setups benefit big time too—especially where multiple diesel or gas generators must take turns evenly or tag-team with the grid.The DEIF PPU/2/GS handles this with minimal manual fuss.
In rescue or remote microgrid scenarios—where reliability is life—it’s critical.Load balancing,automatic protection,clear feedback:this unit brings unbroken compliance and uptime.
Even in hybrid energy systems integrating renewables,the DEIF PPU/2/GS maintains system stability and accurate generator contribution in shifting load conditions.
Whether marine,industrial,or utility—when you need rock-solid synchronization and protection,the DEIF PPU/2/GS is where you anchor your system’s reliability.
