Description
IS200EHPAG1DAB is an Exciter Gate Pulse Amplifier Board manufactured and designed by General Electric as part of the EX2100 Series The IS200EHPA Gate Pulse Amplifier Board (EHPA) is a component of the 100 mm EX2100"m Excitation Control system.
The GE IS200EHPAG1DAB is a high‑voltage Exciter Gate Pulse Amplifier Board designed as a critical component within General Electric’s EX2100 and Mark VI/VIe excitation control systems for power generation equipment. This module serves as the interface between the excitation controller and the power bridge, converting low‑level logic commands into precise high‑voltage gate firing pulses that drive Silicon Controlled Rectifiers (SCRs) in generator excitation circuits.
Its robust design and protective features make it suitable for industrial power generation, turbine controls, and high‑power converter applications where reliable and accurate SCR gating is essential for system performance and stability.
Built to fit within industrial control racks, the IS200EHPAG1DAB features a compact form factor (approximately 17.5 cm × 8 cm × 4.6 cm, ~0.4 kg) and typically runs on a nominal 125 V DC supply sourced from system power modules. Visual indicators such as LEDs provide clear status feedback on power, gate commands, SCR outputs, cooling status, and fault conditions, aiding technicians during commissioning and maintenance.

FAQS
The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
The EHPA receives gate commands from the ESEL through a twisted pair, multiconductor, and shielded cable. These signals are optically coupled, filtered, and AC-coupled before being sent to the Gate Pulse Amplifiers (GPAs), which control the firing of individual SCRs.
How does the EHPA Board handle current conduction monitoring?
The EHPA interfaces with Hall Effect sensors on the EXCS boards to A:monitor the conduction currents across the three-phase bridge input. It receives current status signals from the EXCS and sends the processed information to the system controller.
What type of temperature monitoring does the EHPA support?
The EHPA Board supports temperature monitoring through either an RTD (thermistor) sensor input or a temperature switch input. The RTD input is used for new exciters,while the temperature switch inputs are used when retrofitting an EX2100 control system to an existing bridge with temperature switches.
