GE IS200SCNVG1ADC SCR-Diode Converter Interface Board
The IS200SCNVG1ADC (SCVN) is an interface board designed by General Electric for its Mark VI Speedtronic and Innovation Series drive systems. This board serves as the critical link between the control system and the power semiconductor bridge in SCR-Diode converters.
Technical Specifications
- Brand & Model: General Electric (GE) IS200SCNVG1ADC
- Product Type: SCR-Diode Converter Interface Board (SCVN)
- System Platform: GE Mark VI Speedtronic / Innovation Series Drives
- Compatibility: Used with stand-alone 1000 Amp and 1800 Amp Innovation Series SCR-Diode Converters
- Weight: 10 ounces (approx. 0.28 kg)
- Original Application: Turbine Control for Gas, Steam, and Wind applications
Functional Circuits & Key Features
- SCR Gate Driving: 3 independent gate drive circuits
- Current Sensing: 3 input current sensing circuits
- Voltage Feedback: 2 line-to-line voltage feedback circuits
- DC Link Monitoring: 1 DC link voltage feedback circuit
- Dynamic Braking (DB): 1 IGBT VCE feedback & 1 IGBT gate driver circuit
- Application: For 6-pulse sources driving 3 SCRs per board (cannot drive parallel SCRs from the same board)
System Integration & Mounting
- Rack Slot: Mounts in Slot #6 of the Innovation Series rack
- Control Connection: Connects to J15 on the CABP (Control Auxiliary Base Plate) board
- Backplane Interface: 128-pin P1 connector for communication with other system boards
- External Interfaces: 6 plug connectors for current shunts, DC links, and gate driver connections
- Board Identification: Contains an add-only memory device storing board ID and revision, accessible via the BRDID data line on P1
Power Supply
- Primary Power: Receives Vdc power through the P1 backplane connector
- Secondary Power: Derived from four on-board transformers
- No User Adjustments: Contains no adjustable fuses, switches, or LED indicators
- High Voltage Warning: Four test points are for development only; high voltage is present – user access is not advised
Role in the Control System
- Acts as the essential control-to-bridge interface within the converter
- Translates control signals from the Mark VI controller into gate drive pulses for the SCRs
- Provides critical feedback (current, voltage) from the power bridge back to the controller
- Manages the dynamic braking IGBT circuit for safe energy dissipation
- Integral part of GE's patented Speedtronic control technology for turbine management
Typical Applications
- Gas turbine generator excitation control systems
- Steam turbine control and drive systems
- Wind turbine power converter interfaces
- Industrial high-power DC drive systems using SCR-Diode bridges

- Shipping Dimensions: Approximately 18" x 15" x 15" box.
- Packaged with ESD protection and secure padding.
- Worldwide express shipping via FedEx, UPS, and DHL available.
Frequently Asked Questions (FAQ)
- What converters is this board for? It is designed for stand-alone GE Innovation Series SCR-Diode Converters rated at 1000A and 1800A.
- How many SCRs can it control? It can drive 3 SCRs for a 6-pulse bridge configuration. It cannot drive SCRs in parallel from a single board.
- Where does it install in the rack? It must be installed in the specific Slot #6 of the Innovation Series rack.
- What is the P1 connector for? The 128-pin P1 connector is the main backplane interface for power, communication, and the BRDID data line.
- Are there any status LEDs? No, this board has no LED indicators, fuses, or user-serviceable hardware.
- Can I use the test points? No. The four test points carry high voltage and are for factory development only. User access is dangerous.
- What system does it belong to? It is part of the advanced GE Mark VI Turbine Control System, which incorporates Speedtronic technology.

Consistent, Vibrant Results That Match My Designs Perfectly
Color: 1BK/1C/1Y/1M
I’ve been consistently purchasing this Hiipoo sublimation ink for my sublimation printers, and I’ve been extremely pleased with the results. The print quality is excellent, with vibrant colors and clean transfers every time.
What I really appreciate is how true the final product turns out compared to my original designs. The colors stay accurate, and the finished results look exactly the way I intended, which is very important for my projects and products.
This ink has been reliable and consistent, and I will definitely continue using it for my sublimation work.

Great quality, Great price
Color: 1BK/1C/1Y/1M
Excellent transfer and image quality. It really does work in an Epson Eco tank, as long as you never fill it with the Epson ink.
