PPU-3 并联和保护装置 适合基于PLC编程的功率管理系统使用

PPU-3

DEIF’s PPU-3 control and protection device is simple to operate and configure. This controller is very suitable for power management systems based on PLC programming.

In addition to generator protection and synchronization, the PPU-3 has the following control modes: load distribution, fixed power, fixed frequency, etc. Serial communication makes it easier to interface with PLC, SCADA system and other communications. The device contains a three-phase measurement circuit that displays all measurements and alarm information on a high quality LCD screen. You can also use an optional engine interface card with a separate power supply and microprocessor to turn the PPU-3 into an engine control unit with start/stop and protect functions.

If the PPU-3 processor fails, the engine interface card goes into standby mode to avoid interruption of the engine monitoring function.

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

It is also easy to install and integrate Additional action panels (AOP) for remote control and monitoring. Both displays and panels have dimming functions available for bridge buildings.

With a wide range of optional features and Programmable Logic (M-Logic) applications (USW-3), you can also customize the controller exactly to your requirements. Customizing special functions, logical operations based on input/output, etc.
