الوصف
The GE IS200IGPAG2A is a Gate Drive Power Supply Card used primarily in the GE EX2100 Excitation Control System and is part of the broader GE Mark VI Speedtronic series of industrial controls.1
Its fundamental purpose is to generate the precise, isolated power required to drive the high-power switching components in the system.
⚡ Core Function and Specifications
The IS200IGPAG2A is a high-frequency power supply board that provides the critical power and isolation for the IGBT Gate Driver Boards (like the IS200IGDM series) and other related power control circuitry.2
| Feature | Detail |
| System | GE EX2100 Excitation System and Mark VI Drives |
| Function | Generates regulated, isolated $\text{DC}$ power for gate drive circuits. |
| Output Voltage | Provides a regulated output voltage of $\mathbf{5\text{ V } \text{DC}}$ (with a tolerance of $\pm 10.25\%$). |
| Output Current | Delivers a steady-state output current of $\mathbf{15\text{ A } \text{DC}}$. |
| Switching Frequency | Operates at a high switching frequency of $\mathbf{95\text{ KHz}}$. |
| Features | Includes fuses ($\text{FU1}, \text{FU2}$), a current limit ($\mathbf{18\text{ A } \text{dc}}$), and a soft start capability ($\mathbf{200\text{ milliseconds}}$). |
| Diagnostics | Contains two pairs of $\mathbf{8\text{ LEDs}}$ (amber and green) for status and operational diagnostics. |
| Airflow | Requires a minimum airflow of $\mathbf{80\text{ LFPM}}$ (Linear Feet per Minute) due to its power dissipation ($\approx 10\text{ W}$). |
This board is essential for ensuring that the high-power switches (IGBTs, IGCTs) operate reliably and with the necessary precision to regulate generator voltage or control the turbine’s static starter motor.
