Product Overview

The DS200FGPAG1A is a gate pulse amplifier board from General Electric. This device is part of the LS2100 series. It is also associated with the Mark V series. The board has three primary functions for LCI systems. Specifically, these functions are SCR status monitoring, gate driver, and switching power supply.

The DS200FGPAG1A is not backwards compatible. Therefore, verify your system requirements before ordering. Common revisions include DS200FGPAG1AMD, DS200FGPAG1AKD, DS200FGPAG1AHD, and DS200FGPAG1AFC.

Power Specifications

Input Voltage
The power supply voltage on the DS200FGPAG1A should read 120 VRMS input. The approximate maximum power is 350 VA.

Converter Supply
The 12-pulse converter supply voltage is 2080 or 3300 VAC. Therefore, the DS200FGPAG1A suits high-power industrial applications.

Power Function
Power is delivered to one phase of an SCR bridge. The board also converts AC to DC control voltage. Furthermore, it gathers cell voltage data.

Core Functions

Gate Driver Circuits
The DS200FGPAG1A has two gate driver circuits. These circuits control SCR firing for the inverter.

SCR Status Monitoring
The board monitors SCR status for each three-phase bridge. Three FPGAs are present, one for each SCR bridge. Therefore, the DS200FGPAG1A provides comprehensive bridge oversight.

Test Points
The board has 30 test points in total. Nine are for Gate A. Nine are for Gate B. Twelve are for cell status monitors. Consequently, troubleshooting and validation are straightforward.

Fiber-Optic Connectivity

Connector Count
The DS200FGPAG1A features 15 fiber-optic connectors total. This includes one fiber-optic transmitter. It also includes fourteen fiber-optic receivers.

Network Types
Duplex fiber-optic networks use two receiving ports. Simplex fiber-optic networks use the remaining ports. Therefore, the DS200FGPAG1A supports both network architectures.

Noise Immunity
Electrical interference does not impact fiber-optic messages. As a result, these cables can run alongside 3-phase power cables. This makes the DS200FGPAG1A highly valuable in industrial environments.

Cable Length
Fiber-optic links can extend further than copper wire networks. Adding repeaters can double the length. A maximum of two repeaters can be added. Therefore, long-distance installations are possible with the DS200FGPAG1A.

Fiber-Optic Installation Guidelines

Bend Radius
When designing cable routes, do not exceed the recommended bend radius. Tighter bends may degrade transmission. They may also destroy the cables permanently.

Signal Power
The signal power can be reduced or increased to configure the network. This adjustment depends on cable length and other factors. Therefore, proper configuration is essential for reliable operation.

Environmental and Handling

Static Sensitivity
The DS200FGPAG1A is subject to damage from static electricity. Keep the board in its protective container until installation. Always use a grounding strap when handling the board.

Compatibility Note
The DS200FGPAG1A is not backwards compatible. Therefore, check your existing system version before purchasing.

Physical Specifications

Dimensions
Refer to GE manual GEI-100223 for exact dimensions. The DS200FGPAG1A fits into standard LS2100 rack systems.

Weight
The board weight is approximately 1.20 kg. This is typical for Mark V and LS2100 series boards.

Installation Guidelines

Preparation
First, ground yourself using a static discharge strap. Remove the DS200FGPAG1A from its protective bag only when ready to install.

Mounting
Insert the board into the designated rack slot. Ensure proper alignment with the backplane connector. Secure the board with the retaining screws.

Fiber-Optic Connections
Connect the one fiber-optic transmitter to the upstream controller. Connect the 14 receivers to their respective destinations. For duplex networks, use two receiving ports. For simplex networks, use single receiving ports. Verify the bend radius of each cable is within specifications.

Power Connection
Connect 120 VRMS power to the DS200FGPAG1A input. Verify the power source can deliver 350 VA maximum.

Testing
Use the 30 test points to verify proper operation. Check gate signals for both Gate A and Gate B. Monitor cell status through the 12 dedicated test points.
