Gate Pulse Amplifier Board DS200FGPAG1A is from the LS2100 Series produced by General Electric Industrial Systems. This board has three primary yet basic functions to be used with the LCI (Load Commutated Inverter), these functions are SCR status monitoring, gate driver, and switching power supply. There are also three FGPA’s which are each for every three-phase silicon-controlled rectifier bridge. The power supply voltage on the DS200FGPAG1A should read at an input of 120 VRMs, and the approximate maximum voltage should read at 350 VA.
The SCR status monitoring of the DS200FGPAG1A is used to accumulate cell voltage information, this can be done with up to twelve FHVA devices. Once the voltages have been accumulated they will be sent through an optical data link back to the Load Commutated Inverter device. There are Status circuits within the FGPA model that are used to collect the voltage status that has come from the SCRs, since the polarity from the circuit is not specified the SCR could potentially be blocking the reverse or forward voltages.
When it pertains to the DS200FGPAG1A there are very limited models left on the market but here at AX Control, we offer refurbished models.
