GE DS200GSNAG1AAA GSNA GTO Snubber Buffer Board

GE DS200GSNAG1AAA (functional code GSNA) is a dedicated snubber circuit board under GE DS200 series, specially matched for Speedtronic Mark V turbine control system 

and LS2100 LCI load commutated inverter unit. It absorbs instantaneous surge voltage and voltage oscillation generated during switching actions of high-power GTO thyristors,

 restrains transient overvoltage impact, prevents breakdown damage of power semiconductor devices, and guarantees stable switching operation of rectifier and inverter bridge circuits. 

It is an essential power protection spare part for gas turbine starting system and high-power frequency conversion equipment maintenance.
