Power Generation
Regardless of the type of power generation you have, Steam, Hydro, or Gas Turbine, the DECS-450 provides solutions for your application concerns. It offers high accuracy, reliability, sophisticated protection, programmable logic, and configurable protection to easily and completely adapt to your situation.

Synchronous Motor
Synchronous motor applications are no problem with the DECS-450. A simple click of a button configures the DECS-450's operation, metering and protection to address the unique requirements of a synchronous motor application. Basler has been providing synchronous motor excitation sytems for 50+ years and brings a wealth of application knowledge.

Pumped Storage
With our configurable protection, programmable logic, multiple settings groups and on-the-fly selectability, Basler offers the perfect solution for the demanding needs of Pumped Storage applications.

Retrofit Applications
Basler Electric has a long history of replacing legacy excitation systems made by Basler and other manufacturers. We can offer complete excitation system replacements including power stages as well as "front end" replacements of only the control sections with modern microprocessor-based systems that provide all of the advanced functionality of today's excitation system without a total "rip and replace" approach to the upgrade.

The following Excitation System Application Notes are available:
Implement any Logic Scheme Confidently with Basler's Offline Logic Simulator
Basler Offers Integrated Retrofit Packages for Gas Turbines
Phase Plot Compensator - A New Tuning Aid for Power System Stabilizer Implementation
Modernizing DC Rotating Exciters with Static Excitation Systems

Latest Innovations

Backward Compatibility

Basler implements product strategies that avoid forced obsolescence. With our new innovations, we look at the existing products and make them as backward compatible as possible to make the transition to the new products simple and easy.

The DECS-450 is backward compatible with the DECS-400:

  • The DECS-450 fits in the same mounting cutouts and holes as the DECS-400
  • The DECS-450 has a transition plate attachment that allows the use of the existing wire harness
  • The DECS-450 BESTCOMSPlus® has a program that easily converts the PID and Gain settings of the DECS-400 into those usable by the DECS-450

Basler also provides technical support indefinitely. As long as components are available, we will provide our customers with repair services. Our Technical Support experts are available anytime by phone or email to provide solutions.
