GE DS2020FEBNRX025A Mark V Field Exciter Module, 25 A

General Electric DS2020FEBNRX025A is a field exciter module rated 25 A, from the Mark V turbine control family. The field exciter supplies and regulates the DC field current to the generator's rotating field, which is what sets machine excitation and therefore terminal voltage and reactive output. The 025A in the part number is the 25 A current rating, and it is the figure to match first: a field exciter of the wrong rating is not a substitution question, it is a different machine duty. This module also carries a NATO stock number, 6110-01-464-4878, which is useful if you are sourcing against a government or defence parts list rather than a GE bill of materials. Order this one by the full part number including the trailing revision letters, and check them against the board's own nameplate. GE turbine boards carry suffixes that are not cosmetic -- a board with a different revision can differ in firmware, connector or scaling and is not always a drop-in. GE does not publish a public datasheet for this board, so the order desk verifies the exact revision and system compatibility before quoting rather than matching on the base number alone. These are legacy turbine-control systems supported from surplus, refurbished and repaired stock; tell us whether a repaired exchange unit is acceptable, because it often shortens the lead time considerably. Please email [email protected] to check stock for this item -- send the part number and the quantity you need and the order desk will come back with current availability, lead time and pricing, usually the same business day.
