Features:
- Transfers SCR bridge measurements to the DC2000 control electronics.
- Attenuates line and bridge voltages before the receiving-card interface.
- Converts shunt-derived current signals into differential-frequency outputs.
Placed at the edge of the SCR bridge,
DS200SHVIG1A hands power-section measurements to lower-level DC2000 electronics without making the receiving card a direct high-voltage sensing stage.
Voltage and current information take different routes across
DS200SHVIG1A. Attenuation networks reduce line and bridge potentials, whereas the shunt channel becomes a differential-frequency signal for onward transfer.
Output routing from
DS200SHVIG1A depends on the installed drive arrangement. The PCCA-side connection and the selected DCFB or SDCI companion path must describe the same feedback architecture.
The General Electric DS200SHVIG1A SCR High Voltage Interface Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Power-Section Measurements
- Line Voltage: Attenuator circuits scale incoming line measurements for the control path.
- Bridge Voltage: SCR bridge feedback is reduced before transfer to the receiving card.
- Shunt Input: Low-level current information enters the conversion circuit.
- Output Form: Differential-frequency signals carry the converted measurement onward.
Receiving Board Routes
- PCCA Link: The power connect card supplies the bridge-side interface route.
- DCFB Option: Compatible drives can pass processed signals to a DCFB board.
- SDCI Option: Other configurations deliver the same interface role to an SDCI board.
- Drive Matching: The installed companion-card revision determines the applicable connector path.
Scaling Hardware
- Voltage Networks: On-board components reduce line and bridge potentials.
- Current Option: Jumper-selectable transformer paths provide documented attenuation choices.
- Configuration Basis: Settings depend on the drive bridge and feedback arrangement.
- Separation: High-voltage sensing remains isolated from the low-level receiving circuitry.
Filter Protection Status
- Three Indicators: Each lamp corresponds to a protected filter path.
- Open Fuse: An illuminated indicator identifies the affected fuse circuit.
- Signal Loss: A blown filter fuse can remove one measurement path while others remain active.
- Access Safety: High-voltage cabinet isolation is required before inspecting the fuse section.
