The IS200EDCFG1A IS200EDCFG1ACB functions as an exciter DC filter board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EDCFG1A serves as the standard version for DC filtering. Its variant, the IS200EDCFG1ACB, includes a conformal coating for extra circuit protection. Both boards filter DC signals for steam and gas turbine excitation systems.
Core Technical Specifications
This board provides multiple filter circuits for DC voltage smoothing. You will also find common mode chokes for noise reduction. The board stores minimal energy but uses capacitors for signal conditioning. Meanwhile, the backplane interface handles all power and monitoring functions.
