Description
Programmable digital excitation.
Did you know
- The ABB UNITROL P excitation system was first introduced in 1994. By early 2011, it entered a "Limited Phase" in ABB's product lifecycle, indicating its technology was over 25 years old.
- The UNITROL P is an older generation static excitation system, succeeded by models like the UNITROL 1000 series for smaller to medium applications, and the UNITROL 6000 series for larger, more demanding power plant and industrial applications.
- The UNITROL P utilized Programmable High Speed Controller (PHSC) technology to achieve strong controller performance for synchronous machines.
