GE IS200EPDMG1ABA is a Power Distribution Board for Mark VIe systems, distributing stable DC power to exciter control modules. It has overload/short-circuit protection, supports multi-channel power output, offers isolation, works at -40°C to +70°C, meets UL/CE, ensuring reliable exciter system power supply.
detectors (IS200EGDMH1A), and I/O boards (IS200EMIOH1A)—while integrating robust protection
mechanisms to prevent power-related failures. Unlike generic power distribution units, it is purpose-
built for excitation system demands: it features dual redundant power inputs (eliminating single
points of failure), per-channel overcurrent protection (via resettable fuses), and EMI-shielded power
traces to ensure clean power delivery even in high-voltage industrial environments.
Designed as a compact, rack-mountable board (compatible with EX2100 standard control racks), it
simplifies wiring with clearly labeled terminal blocks for input power and output channels, reducing
installation errors. The front panel includes LED indicators for input power status (one per redundant
input) and output channel health (one per connected module), enabling technicians to quickly
identify power disruptions. Its rugged construction includes a conformal-coated PCB (per IPC-CC-
830B Class 3) to resist dust, moisture, and chemical contaminants—critical for reliability in power
plants, steel mills, and petrochemical facilities. Whether supporting simplex or triple-redundant (TMR)
excitation configurations, the IS200EPDMG1ABA ensures consistent power flow to every component,
acting as the “power backbone” that safeguards the excitation system from voltage spikes,
overloads, or input power failures.

FAQs
What is an Exciter Power Distribution Module?
An Exciter Power Distribution Module is a device used in electrical power systems to regulate and distribute power to the generator's exciter, which is responsible for providing the necessary field current to the generator's rotor.
Why is an Exciter Power Distribution Module important?
This module is critical for maintaining stable voltage levels in the generator, ensuring reliable and efficient operation of the power system. It helps prevent voltage fluctuations, which can lead to equipment damage or power outages.
How does an Exciter Power Distribution Module work?
The module regulates the voltage applied to the generator's field winding by adjusting the exciter current. It uses automatic voltage regulators (AVRs) to monitor and control the output voltage, maintaining stability despite load changes
