Features:
- Translates floating bridge-shunt feedback into differential pulse streams.
- Applies selectable scaling to line-current and high-voltage measurement paths.
- Links M-frame power hardware with DCFB or SDCI and PCCA electronics.
Signal conversion on
DS200SHVMG1A keeps the positive and negative current channels distinct. Each VCO develops a frequency proportional to its low-level shunt input for use by the downstream controller.
The line-current branch on
DS200SHVMG1A can introduce 10:1 attenuation before the measurement leaves the board. This selection accommodates the documented current-transformer signal range without changing the control-card interface.
Separate source and converter monitoring branches on
DS200SHVMG1A use range jumpers to choose either a direct measurement path or additional attenuation according to the M-frame drive voltage.
The General Electric DS200SHVMG1A SCR High Voltage M-Frame Interface Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Current Feedback Chain
- Shunt Channels: Positive and negative floating shunt inputs remain separate.
- VCO Stage: Voltage-controlled oscillators translate millivolt feedback to pulse frequency.
- Output Form: Differential frequency signals extend from 0 to 500 kHz.
- Destination: Converted current feedback proceeds to the DCFB or SDCI control path.
Scaling Selection
- Low Range: The attenuation network is bypassed for 240-600 VAC equipment.
- High Range: Additional attenuation is inserted for 601-1000 VAC operation.
- Line Current: A selectable 10:1 CT path changes AC current scaling.
- Setup Rule: Voltage and current choices must agree with the installed drive rating.
Control Connections
- Controller Side: The board interfaces with either a DCFB or an SDCI control board.
- Power Side: PCCA provides the associated power-connect interface.
- Measured Points: Line, motor and SCR bridge voltages use dedicated paths.
- Frame Limit: This SHVM group is assigned to DC2000 M-frame hardware.
Hardware Configuration
- Jumper Bank: Seventeen positions, JP1 through JP17, define board options.
- Range Choice: Several positions select voltage attenuation or bypass.
- Current Choice: The CT branch has its own scaling selection.
- Commissioning Boundary: The complete pattern must match the cabinet drawing and drive nameplate.
