Features:
- Drives the six SCR gates of a 100 mm thyristor bridge.
- Accepts firing commands from the ESEL selector board.
- Returns conduction, airflow and temperature status from the power bridge.
One gate pulse amplifier is assigned to every EX2100 power conversion module.
The board directly controls bridge SCRs rather than issuing a supervisory software command.
Visual indicators divide power, firing and protection states into separately readable conditions.
For 100 mm bridge-control enquiries, Apter Power can assist with the General Electric IS200EHPAG1A Exciter Gate Pulse Amplifier Board and available documentation.

Connecting IS200EHPAG1A to the 100 mm bridge
- Application size: EHPA is the amplifier type selected for 100 mm thyristors.
- SCR count: The attached three-phase bridge contains six controlled devices.
- Dedicated board: Each power conversion module receives one amplifier board.
- Direct control: Gate outputs from the board fire the bridge SCRs directly.
Power path inside IS200EHPAG1A
- Source: EPDM provides a nominal 125 V dc feed.
- Conversion: An on-board dc-to-dc stage generates the required gate power.
- Input range: The converter supports firing across the control-supply operating range.
- Power status: A dedicated indication separates gate-supply state from firing activity.
Signals returned through IS200EHPAG1A
- Conduction: Bridge-current activity is reported through the amplifier interface.
- Airflow: Fan rotation or cooling-flow status reaches the control through this path.
- Temperature: Thermal monitoring identifies bridge heating conditions.
- System boundary: The same board carries commands toward the SCRs and status back from the bridge.
Reading IS200EHPAG1A indications
- Firing state: Output indicators show when gate pulses are being issued.
- Bridge current: Separate status identifies conduction into the thyristor bridge.
- Cooling condition: Fan and temperature indications expose cooling-related conditions.
- Fault separation: Alarm, fault, line-filter and gate-power states are displayed independently.
