IS200DSFCG1A

The IS200DSFCG1A is a Driver Shunt Feedback Board designed and developed by General Electric as part of the Speedtronic Mark VI series. It offers protection, feedback, and control functionalities essential for power conversion systems in drive/source applications, particularly within the Innovation SeriesTM. With features such as MOV protection, jumper pins for customization, current sensing, fault detection circuits, galvanic and optical isolation, and compatibility with source bridges and AC drives, the board ensures high reliability and system performance.

Product Attributes

• Metal Oxide Varistor (MOV): A circular red MOV, located near the upper left corner, protects the board and connected circuitry from transient voltage spikes by diverting excess electrical energy to ground.
• Jumper Pins: Six jumper pins in three pairs, labeled PL, PL1, and PL2, near the upper center, allow for configuration and customization of settings or connections on the board, enhancing flexibility in system integration.
• Current Sensing and Fault Detection Circuits: The board includes a current sensing circuit for accurate current measurement and monitoring, ensuring precise control and overcurrent protection. It also features a fault detection circuit to identify system faults or abnormalities.
• Galvanic and Optical Isolation: Feedback and driver circuits are designed with galvanic and optical isolation to prevent electrical noise and interference, improving signal accuracy and system safety by isolating electrical potentials.
• Compatibility with Innovation SeriesTM Source Bridges and AC Drives: The board is compatible with 1000 Amp and 1800 Amp PWM source bridges and AC drives, serving as an interface between the drive bridge personality board and the drive control system for seamless integration.
• Mounting and Orientation: The board is mounted to the upper and lower IGBT modules in each phase leg, using gate, emitter, and collector connections for secure positioning. Proper orientation ensures alignment with mounting holes and electrical/mechanical integration.

Key Features

• Shunt Feedback: A built-in shunt resistor provides feedback on system current, helping regulate the current to prevent overloading and ensure smooth operation.
• Amplification: The board features an amplifier to boost input signals, making them easily processed by the control system.
• Isolation: Provides electrical isolation between input and output signals to protect the control system from electrical noise and surges.
• Signal Output: Outputs high-level signals that can control motors, valves, or interface with PLCs or DCS systems.
• Protection: Overvoltage and short-circuit protection safeguards the connected equipment from damage.
• Modularity: The modular design allows easy replacement or upgrading of the board as needed.

Excitation Control System

• The excitation control system supplies DC power to the synchronous generator's field.
• The exciter controls the generator's AC terminal voltage and/or reactive volt-amperes using field current. Exciters are housed in NEMA 1 metal cabinets, designed as freestanding, floor-mounted units with top or bottom cable entry.
