Description
The General Electric DS200SHVMG1A (paired with manufacturing revision code DS200SHVMG1AFE) is a specialized SCR High-Voltage M-Frame Interface Board (SHVM) engineered for GE’s Mark V control platform and heavy industrial drive or excitation systems. This circuit board acts as a critical intermediary interface between high-voltage M-frame SCR (Silicon Controlled Rectifier) power bridges and system power supply/controller cards, ensuring precise voltage and current feedback handling in power generation and turbine automation applications.
📊 Technical Specifications

- Supported Power Boards: Interfaces directly with DCFB and SDCI power supply boards alongside PCCA power connect cards
- Signal Conversion: Incorporates voltage-controlled oscillator (VCO) floating shunt isolator circuits to convert bridge shunt signals (-500 mV to +500 mV) into differential frequency outputs (0 to 500 kHz)
- Current Attenuation: Features jumper-selectable 10:1 current transformer (CT) attenuation for AC line currents (phases A and C)
🛠️ Operation Guidelines & Installation
Installation, testing, and replacement must be performed strictly by qualified industrial drive technicians or certified control system engineers. Important Safety Note: The SHVM board features floating circuitry connected directly to high-voltage bridge potentials. Always lock out, isolate, and completely de-energize all primary high-voltage inputs, AC line feeds, and control power sources, and wait for internal bus capacitors to discharge fully before handling the board to prevent severe electrical shock or electrostatic discharge (ESD) damage. Wear an anti-static grounding wrist strap while mounting or servicing the card.
🔌 Power-Up and Power-Down Sequence
Verify that all multi-pin plug connectors (PL series), heavy stab-on power links, and configurable jumpers are securely seated and torqued prior to startup. Check that current transformer attenuation jumpers are correctly configured for your line voltage range (bypassed for 240–600V; engaged for higher voltage systems). Energize control power supplies first, followed by main high-voltage application loops. For maintenance or shutdown, isolate high-voltage power feeds completely before inspecting wiring.
📝 Product Usage Instructions
The SHVM board processes harsh high-voltage signals from the SCR bridge, isolating them safely and translating them into usable frequency and voltage references for the drive’s power supply and control regulators. Note that this board does not feature onboard diagnostic LEDs, test points, or fuses; all adjustments are managed through physical jumpers. Maintain a clean, dry, and properly temperature-regulated drive cabinet environment.
❓ Common Questions (Q&A)
Q: What is the primary function of the DS200SHVMG1A board?
A: It provides signal isolation, scaling, and high-voltage interfacing between M-frame SCR bridges and the drive’s power supply/control cards (such as DCFB or SDCI boards).
Q: Does the board require user configuration during installation?
A: Yes, it utilizes 17 onboard configurable jumpers to set up 10:1 current transformer attenuation based on your specific AC line voltage and motor ratings.
Q: Are there any active diagnostic indicators on the SHVM board?
A: No, the SHVM board design does not include onboard LEDs, fuses, or test points; system health is monitored via the main drive control and regulator displays.
