Overview

The DECS-450 is a microprocessor based, high performance, extremely reliable

excitation controller for positive and positive/negative forcing excitation systems.

It supplies control voltage to an external bridge, which supplies dc energy to the

main or exciter field of a synchronous machine, making it compatible with any

size machine. The DECS-450 comes in many configurations to satisfy specific

requirements and redundancy needs. Basler offers customized and standard

solutions to fit a wide variety of applications.

Benefits

• With its high levels of flexibility and reliability, the DECS-450 is

suitable for virtually any synchronous machine.

• Reduce your setup time with Basler’s intuitive BESTCOMSPlus®

software that simplifies complex setup with simple drag-and-drop

programmable logic (BESTlogic™Plus), visual real-time strip chart

capabilities, and cutting edge auto PID selection capabilities.

• The revolutionary auto tuning function automatically establishes

optimum PID and gain settings, taking the guesswork out

of system setup, reducing commissioning time and cost

while maximizing overall system performance (Patent: US

2009/0195224 A1).

• Avoid costly generator damage and improve overall system

stability with an optional integrated PSS that utilizes the “integral

of accelerating power” to safely dampen local mode, inter-area, and

inter-unit power oscillations.
