Series:Parallel connection and protection

  Product Description

  The PPU-3 control and protection device of DEIF is easy to operate and configure,making it very suitable for power management systems based on PLC programming.

  feature

  Highly reliable

  Excellent performance

  User friendly interface

  The PPU-3 DEIF parallel connection and protection device is easy to operate and configure,and the PPU-3 control and protection unit of DIF is an ideal controller for a PLC based power management system.

  Convert the PPU3 into an engine control unit with start/stop and protection functions.The optional engine interface card also has a separate power supply and independent microprocessor.

  In the event of a ppu3 processor failure,the engine interface card will enter backup mode and ensure uninterrupted engine monitoring.

  The PPU-3 control and protection device of DEIF is easy to operate and configure,making it very suitable for power management systems based on PLC programming.

  In addition to generator protection and synchronization functions,PPU-3 also has the following control modes:load distribution,fixed power,fixed frequency,etc.Serial communication makes it easier to interface with PLC,SCADA systems,and other communication interfaces.This device includes a three-phase measurement circuit that can display all measured values and alarm information on a high-quality LCD screen.An optional engine interface card with independent power supply and microprocessor can also be used to convert the PPU-3 into an engine control unit with start/stop and protection functions.

  If the PPU-3 processor malfunctions,the engine interface card will enter standby mode to avoid interruption of engine monitoring function.

  If a shutdown alarm occurs,the engine will automatically stop.Therefore,it is a reliable solution for controlling and monitoring marine generator sets.

  Additionally,additional operating panels(AOPs)can be easily installed and integrated to meet remote control and monitoring needs.Both the display and panel have dimming functions that can be used for bridges.

  With a wide range of optional features and programmable logic(M-Logic)application software(USW-3),you can also customize controllers that fully meet your requirements.Customizing special functions,performing logical operations based on input/output,and so on

  application area

  The PPU-3 DEIF parallel connection and protection device is widely used for parallel connection and protection of various power systems,including power plants,substations,industrial facilities,etc.
