DS200FGPAG1A

The DS200FGPAG1A is a Gate Pulse Amplifier Card that provides gate power for one phase of the SCR bridge, monitors SCR status, and converts AC power to DC.  

The instruction manual for the DS200FGPAG1A is GEI-100223 and is available from AX Control upon request.

The three main functions are switching the power supply, gate driver, and SCR status monitoring. The purpose of the power supply switching function is to convert the received AC voltages into the required DC voltages needed for gating and status functions. The purpose of the SCR status monitoring is to accumulate cell voltage information from the attached FHVAs and relay the information via an optical serial data link to the LCI controller. The gate driver is used to supply any gate power for one phase of an SCR bridge. More information regarding these functions can be found on the front page of the GEI-100223 Gate Pulse Amplifier User's Guide. 

There are nine test points in Gate A, and many of them have individual descriptions with different nomenclatures, some are as follows: TP101, nomenclature 1PUSH1, description Logic 1= command to start to push cycle; TP105, nomenclature VLINKA, description primary voltage; and TP110, nomenclature 0RELA, description Logic 0 = release gate inhabits. 

The FGPA will accept a power input of 120 Vrms Ù 20%, 50/60 Hz, approximately 350 VA maximum. There are four different points on the FGPA model than can accept voltages which are as follows, P15 while not monitored will typically accept a power supply of 13.5-14.5 VDC,  P5 accepts voltages between 4.7-5.1 VDC, P90 accepts greater than or equal to 81 VDC, and P40 will accept greater than or equal to 25 VDC. 

There are two different sources, those being the gate pedestal and the gate backporch.
