Product Description
DS200SHVMG1AFE is a General Electric designed high voltage M-frame interface board. As a member of the Mark V series, this card can be used across a range of GE brand drives and exciters, although the Mark V Series has specific applications in the control and management systems of wind, steam, and gas turbine automated drive assemblies. An interface medium is provided when this board is installed. Communications between the SCR bridge of the M-frame drive, the power supply board (either DCFB or SDCI), and the power connect card (PCCA) are created with this interface board. While this DS200SHVMG1AFE printed circuit board or PCB for short is definable as a SCR High Voltage M-frame Interface Board, it is by no means considered the original product of this functionality to exist within the Mark V Turbine Control System Series; that would be the DS200SHVMG1 SCR High Voltage M-frame Interface Board missing all three of this DS200SHVMG1AFE product's three significant product revisions.
Hardware Tips and Specifications
Signal conversions and electrical functions are provided when this board is installed in the drive. This card produces differential frequency outputs rated between 0 and 500 kHz by converting shunt signals ranging from -500 to 500 mV. The DC positive and negative shunts found on the voltage controlled oscillator (VCO) circuit is responsible for performing these conversions. Newly converted digital signals are then sent to the power supply board as well as the power connect card. A 10:1 current transformer attenuation is integrated into the AC line current. Before attempting any installation or replacement of this DS200SHVMG1AFE model of General Electric printed circuit board, it is important to wait a few minutes for the voltages present in this device's series of capacitors to die out; as capacitors exist as one of the standardized Mark V Turbine Control System Series voltage-limiting hardware components available with this model. Some of the other voltage-limiting hardware components in the assembly of this DS200SHVMG1AFE PCB included various diodes, resistors, and integrated circuits helping to avoid DS200SHVMG1AFE product damage by static electricity or excess voltages. Additionally, almost the entirety of the hardware components elements made available to this DS200SHVMG1AFE printed circuit board are protected by thick rudimentary layer of normal printed circuit board coating, which envelops individual hardware elements on a functional priority basis.
Users can select desired attenuation by configuring one of the 17 jumpers available in this General Electric product's assembly. The exact placement and function of each of this extended series of jumpers is explained in the original DS200SHVMG1AFE instructional manual available above through our manuals tab. It it important to realize that the first eight jumpers in this DS200SHVMG1AFE PCB's assembly all share a similar functionality. These jumpers have been included in the DS200SHVMG1AFE board's assembly to select 10:1 attenuation for both phase A and phase C current transformers. With this being known, jumpers JP1-JP8 in this DS200SHVMG1AFE SCR High Voltage M-frame Interface Board should all be set to the same position; effectively either bypassing or selecting 10:1 attenuation. Most of the other jumpers in the assembly of this DS200SHVMG1AFE Mark V Series product select for different line attenuation strings in this DS200SHVMG1AFE board's configuration. Before making an ultimate purchase decision on this DS200SHVMG1AFE product offering, its is crucial to understand that its original instructional manual-introduced performance specifications and dimensions have been altered through its extended three-fold revision history.
