IS200EGPAG1A OBS gate pulse amplifier card

Part Number IS200EGPAG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series EX 2100e Function Module Availability In StockIS200EGPAG1A is an OBS Gate Pulse Amplifier Card manufactured by General Electric as part of the Mark VI series used in gas turbine control systems. Each of the Speedtronic systems has improved upon the preceding iteration. As a result, the MKI's modest (by today's standards) circuit boards have been replaced by the multi-frame Mark VI, which includes triple redundant backups and Ethernet functionality. 

The Mark VI uses a Windows-based PC HMI, or operator interface, that provides one-stop access to critical system data, including time tags for alerts and events. The Exciter Gate Pulse Amplifier Card is an Exciter Gate Pulse Amplifier Card. 

The Card is intended to interface with the power bridge's control. It also accepts gate orders from the ESEL board (up to six) and utilizes them to regulate SCRS gate firing on the bridge. A line of LEDs runs along the front board edge of the components. These are used to show output firing, bridge temperature, bridge currents, alarm or fault conditions, and cooling fan rotation, among other things. There are thirteen plugs on the board. Six two-position plugs run along the left edge, one two-position plug runs along the upper right corner and another runs along the right edge, one six-position plug runs along the front edge, and three four-position plugs run along the front edge, and a single twelve-position plug runs along the front edge.GATEPULSE AMPLIFIER

When the circuit board controls the bridge, it will also receive the gating command from the ESEL circuit board, and then generate trigger pulses for six silicon controlled rectifiers (SCR). 

IS200EGPAG1A is not only the interface of the above mode, but also the interface of bridge airflow, temperature monitoring and conduction current feedback. The position of the board is not in the auxiliary cabinet, but in the power conversion cabinet.On model IS200EGPAG1A, there are LEDs to indicate the current status flowing into the bridge, line filter, bridge temperature, output ignition, grid power supply, alarm/fault condition and cooling fan rotation. Please note that when the motherboard is connected to the power conversion module (PCM), one EGPA is used for each PCM.A separate manual contains a more detailed description of the IS200EGPAG1A model. The name of the manual is GEI-100461 IS200EGPA exciter gate pulse amplifier board. An overall series of manuals, namely GEH-6632 EX2100 Excitation Control Guide, is attached to the "Manual" tab of this page. Information about IS200EGPA can be found on pages 26, 34 and 51.
