MK III

Powergenics repairs and supplies GE Mark III (MK III) turbine control system boards for gas and steam turbine applications. The GE Mark III is a legacy control platform still operating in power plants worldwide, making reliable repair and sourcing critical for plant uptime.

Our MK III inventory includes speed control cards, temperature input boards, I/O modules, sequencer cards, and power supply components. Because Mark III parts are no longer manufactured, Powergenics’ repair capability and refurbished stock are essential resources for facilities maintaining these systems.

All GE Mark III repairs include full functional testing and a 3-year warranty. With 25+ years of experience on legacy GE turbine controls, our engineers understand the nuances of MK III fault diagnosis.
