About the DS200SHVMG1A
The General Electric DS200SHVMG1A is a high voltage M-frame interface board. This unit is a member of the Mark V series of optional and replacement boards. When installed, this card provides an interface medium from the M-frame drive’s SCR bridge to the power supply board (DCFB or SDCI) as well as powerconnect cards (PCCA). A number of GE brand exciters and drives can have this board installed in its cabinet, although this DS200SHVMG1A PCB has specific applications in the control and management systems of wind, steam, and gas turbine automated drive assemblies.
This DS200SHVMG1A SCR High-Voltage M-frame Interface Board is not the originally-manufactured device of its functionality to feature within the Mark V Series; that would be the DS200SHVMG1 parent printed circuit board missing this DS200SHVMG1A Board's A-rated functional product revision.
Hardware Tips and Specifications
When installed, DS200SHVMG1A provides an array of functions to the drive, which is achieved through its inclusion of a specific set of functionality-introducing hardware components and component specifications. Shunt signals between -500 and 500 mV are converted into differential frequency outputs between 0 and 500 kHz. These signals are then sent to either the DCFB or SDCI boards or the PCCA card. Using DC positive and negative floating shunts, the VCO (voltage controlled oscillator) circuits act as the conversion points for the voltages. This card also offers the AC line currents a 10:1 current transformer attenuation. Attenuation is user-selectable using the 17 onboard configurable jumpers. If the AC line voltage ranges from 240 to 600 V, bypass the attenuators. Should voltages range between 601 to 1000 V, they should be included.
This DS200SHVMG1A printed circuit board features many more general, Mark V Series-standardized hardware components and component specifications in its assembly beyond just its functional component inclusions. For starters, the internal assembly of this DS200SHVMG1A printed circuit board makes use of a standard number of voltage-limiting and suppressing hardware components, such as:
- capacitors
- diodes
- rectifiers
Additional voltage protection for this static-sensitive DS200SHVMG1A printed circuit board exists in the form of its normal style of PCB protective coating and the insulated rings that have been carefully installed over this DS200SHVMG1A product's factory-drilled installation holes.
The normal style of PCB coating unique to this DS200SHVMG1A product offering was discovered upon an analysis of its DS200SHVMG1A functional product number, which contains functional chunks naming different specifications for the DS200SHVMG1A board itself. Some of the other DS200SHVMG1A board-specific information embedded in the DS200SHVMG1A functional product number includes this DS200SHVMG1A SCR High-Voltage M-frame Interface Board's normal Mark V Series assembly, domestic location of original manufacture, SHVM functional product abbreviation, group one Mark V Series grouping, and finally its possession of an A-rated functional product revision. Any manufacturer provided installation parameters for both the drive and the board should be met.
