GE EX2100 excitation system IS200EGPAG1ABC EGPA gate pulse amplifier board

GE EX2100 excitation system IS200EGPAG1ABC EGPA gate pulse amplifier board

IS200EGPAG1ABC is an EGPA gate pulse amplifier board that is compatible with the GE EX2100 excitation system and belongs to the Speedtronic Mark VI/Mark VIe gas turbine control system. IS200EGPAG1ABC is used to receive the weak trigger pulse signal output by the main control ESEL board, amplify the power, generate high-power gate pulses, drive 6 SCR thyristor devices in the excitation rectifier bridge, and control the excitation current of the generator. IS200EGPAG1ABC can simultaneously collect the temperature of the power bridge radiator, the status of the air duct, and the feedback signal of SCR conduction, monitor the working conditions of the power unit in real time, and immediately report to the system controller in case of overheating, pulse loss, and other faults, triggering an alarm or protection trip. It is the core driving board that controls the SCR rectifier bridge in the excitation regulation circuit of the generator set.

Product features

1. Specially designed for the EX2100 excitation system, it outputs six SCR gate drive pulses to directly control the excitation rectifier bridge.
2. Dual temperature switch acquisition, with the ability to set two-level temperature thresholds, radiator high temperature warning, and trip protection.
3. Onboard 5 sets of jumpers for easy on-site configuration and adaptation to different power bridge hardware solutions.
4. Real time monitoring of SCR conduction status, air duct flow rate, pulse loss, and comprehensive diagnosis of excitation power unit faults.
5. Multiple LED status indicator lights for intuitive viewing of pulse output, faults, and power status, facilitating on-site maintenance.
6. The PCB board is coated with a three proof conformal coating, which is resistant to moisture and dust, and suitable for high temperature and dusty working conditions in power plant excitation cabinets.
7. Support hot swappable replacement under redundant racks, without interrupting the excitation operation of the entire unit during maintenance.
8. The backplane connector communicates with the ESEL control board, receives pulse commands, and sends back power bridge monitoring data.
9. Industrial grade components, wide temperature and anti vibration, suitable for long-term uninterrupted continuous operation of generator sets.
10. Special spare parts for the old EX2100 excitation system, with mechanical interfaces and drive timing fully compatible with the original system.
