GE DS200SHVMG1AFE SCR High Voltage Interface Board 330mm x 200mm

GE DS200SHVMG1AFE SCR High Voltage M-Frame Interface Board 

Product Details:

The GE DS200SHVMG1AFE is a SCR High Voltage M-Frame Interface Board designed for GE’s EX2000 Series and Mark V Turbine Control System—one of the final GE Mark lines to use patented Speedtronic technology. A revised variant of the original DS200SHVMG1 parent board, it acts as a critical interface between an M-frame drive’s SCR bridge, DCFB/SDCI Power Supply Boards, and PCCA Power Connect Cards, supporting wind, steam, and gas turbine drive control systems.

Its core functions include converting shunt signals into differential-frequency outputs via DC positive/negative floating shunt isolator voltage-controlled oscillator circuits, then transmitting these signals to power supply/connect boards. It also provides configurable attenuation: jumper-selectable 10:1 current transformers for AC line currents to handle currents exceeding 144 mA; line voltage attenuators and DC bridge voltage resistor strings.

Hardware includes 17 configurable jumpers, voltage-limiting components, and a functional priority-based PCB coating. Installation requires waiting for capacitors to discharge to avoid voltage hazards; it is static-sensitive, shipped in protective packaging by suppliers like AX. It belongs exclusively to Mark V Group 1 and is not backward compatible with earlier base models due to revisions. Suppliers like WOC offer replacement, repair, and warranty-backed unused/rebuilt units, with 24/7 expert support.

Key Features:
Dual-System Compatibility: Works with EX2000 Excitation Control Systems and Mark V Turbine Control Systems, leveraging Speedtronic technology for reliable turbine drive operation.

Signal Conversion & Attenuation: Converts shunt signals to differential frequencies and offers configurable CT/voltage attenuation, adapting to diverse AC line voltage and current needs.

Jumper-Configurable Flexibility: 17 jumpers enable precise customization to system requirements, guided by OEM manuals.

Safety & Durability: Voltage-limiting components and PCB coating protect hardware; static-sensitive design and capacitor discharge requirements ensure safe handling/installation.

Legacy Support: Backed by suppliers offering replacement, repair, and 24/7 support, extending the lifespan of Mark V systems.
