GE DS200SHVMG1A DS200SHVMG1AGE SCR M-Frame Board

Key Technical Specifications

This GE DS200SHVMG1A DS200SHVMG1AGE board handles 600V AC maximum input voltage. It carries 100A continuous current through six SCR devices. The unit measures 32 cm in length, 24 cm in width, and 7 cm in height. Its total weight reaches 1.6 kg without any packaging materials.

The GE DS200SHVMG1A DS200SHVMG1AGE includes six SCR power modules in a three-phase bridge. Additionally, it features one fiber optic input port for gate firing signals. A single 12-pin terminal block connects the AC input and DC output. The board contains 6 SCRs, 6 gate drivers, 3 snubber circuits, 4 voltage sensors, and 12 capacitors.

GE DS200SHVMG1A DS200SHVMG1AGE stores energy using three series electrolytic capacitors. Together, they provide 1000 µF at 1000V rating for DC link smoothing. This energy storage maintains output during 20 millisecond commutation notches. Therefore, the board delivers clean DC current to the load.

Design and Integration

Both the GE DS200SHVMG1A and DS200SHVMG1AGE versions share identical SCR power topology. These boards use heavy-duty aluminum baseplates with thermal compound for heat dissipation. Consequently, the GE DS200SHVMG1A DS200SHVMG1AGE operates reliably from 0°C to +50°C with forced air cooling.

For installation, you need M6 screws for the six mounting holes. The board draws 200 mA typical control power from an external 24V DC supply. Each SCR dissipates approximately 40 watts at full load current. We recommend using a 120A fast-acting fuse and a dedicated heatsink with fan.

Practical Application

This SCR M-frame board converts AC power to controlled DC for motor drives and exciters. It receives firing pulses via the fiber optic link from the regulator board. The GE DS200SHVMG1A DS200SHVMG1AGE also provides voltage feedback signals for closed-loop control. Therefore, it forms the power stage of medium-voltage DC drive systems.
