DECS-250E, Digital Excitation Control System

The DECS-250E Digital Excitation Control System provides accurate and reliable regulation, control, and protection for synchronous motors or generators. Three DECS-250E models are available to supply 50 Adc, 100 Adc, or 200 Adc of excitation current continuously in a static or rotary exciter application. All DECS-250E components are housed in a compact enclosure which makes for a simple and cost-effective installation in a variety of applications.

Benefits

  • Reduce your setup time with Basler's intuitive BESTCOMSPlus® software that simplifies complex setup with simple drag-and-drop programmable logic, visual real-time strip chart capabilities, and cutting edge auto PID selection capabilities.
  • The revolutionary auto tuning function automatically establishes optimum gain settings, taking the guesswork out of system setup, reducing commissioning time and cost while maximizing overall system performance.
  • The Offline Simulator in BESTlogic™Plus helps test and troubleshoot logic without the need for expensive hardware.
  • A 50, 100, or 200 ampere positive forcing rectifier bridge can be selected to provide optimum response to the generator main or exciter fields.
  • Compact design for all excitation ratings allows the static excitation control system to be contained in a small enclosure.
  • Preconfigured programmable logic adds flexibility. A standard configuration can be adapted to create a custom logic scheme.
  • A full suite of generator and motor protection features for accurate fault detection and clearing, which helps eliminate dangerous and damaging conditions to the generator or motor.
  • Extensive communication options for easy integration into a wide variety of control systems.

    • One Good DECS Deserves Another (616.8KB)
      Throughout Taiwan’s history, many government-owned power plants were built to supply power for the main island of Taiwan and its outlying islands. Basler excitation systems and protective relays are widely used in these plants.
    • One of Basler’s First SSE’s Still Carrying the Load of a 2MW Generator (1.8MB)
      From the early days of rotating exciters to today’s digital static excitation systems using power semiconductors, Basler’s generator excitation systems have made great strides in innovation and efficiency while always maintaining their reputation for legendary reliability.
