The IS200SCNVG1A IS200SCNVG1ADC controls SCR bridges for AC to DC conversion. This board generates firing pulses for six thyristors in three-phase bridges. Its rectangular frame measures 235 millimeters in width. The board height reaches 170 millimeters exactly. Depth stays at a compact 26 millimeters. You will find this unit weighs approximately 0.88 kilograms. Therefore, installation requires four standard mounting screws. Two ribbon cable connectors deliver firing pulses to power modules.
Physical Layout and Connectors
Each ribbon connector carries six independent gate drive signals. A separate terminal block accepts synchronizing voltage from the AC line. Four status LEDs indicate bridge activity and fault conditions. Four plated mounting holes align with standard GE rack patterns. You can mount this board vertically or horizontally inside the cabinet.

Internal Design and Energy Storage
The IS200SCNVG1A IS200SCNVG1ADC contains exactly 256 discrete components. A 1800 microfarad capacitor bank stores energy for stable firing pulses. This bank ensures consistent gate drive under fluctuating loads. Twelve optocouplers provide complete isolation between logic and power sections. Each optocoupler withstands 2500 volts RMS continuously. Dedicated phase-locked loops track incoming line frequency accurately.
Operational Performance
This SCR bridge board generates firing angles from 0 to 180 degrees. It synchronizes with three-phase AC input voltages automatically. Moreover, the board includes current limit and overcurrent protection logic. You can set ramp rates for soft starting the converter. The unit provides pulse trains or single-shot firing modes. Six test points allow you to monitor individual channel outputs. Consequently, you achieve smooth DC output from thyristor bridges. GE designed this board for heavy industrial drives. Its rugged components withstand high surge currents and voltage transients.
In summary, the IS200SCNVG1A IS200SCNVG1ADC delivers reliable SCR control. Use this board for DC drives or battery chargers. It ensures precise firing across all operating conditions. Order this SCR bridge board for your power conversion system.
