The IS200EPBPG1A IS200EPBPG1AAC functions as an exciter snubber board for turbines. This printed circuit board belongs to the Mark VI Speedtronic series from General Electric. The IS200EPBPG1A serves as the standard version for snubber protection. Its variant, the IS200EPBPG1AAC, includes a conformal coating for enhanced circuit protection. Both boards provide snubber circuits for steam and gas turbine excitation systems.
Core Technical Specifications
This board provides multiple RC snubber networks for voltage spike suppression. You will also find high-voltage diodes for additional protection. The board stores minimal energy but uses capacitors for transient absorption. Meanwhile, the backplane interface handles all power and monitoring functions.
