DS200SHVMG1A GE SCR High Voltage M-frame Interface Board Mark V Series

DS200SHVMG1A GE SCR High Voltage M-frame Interface Board Mark V Series

Description:

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.

The DS200SHVMG1A provides a range of functions for the driver. Shunt signals between -500 and 500 mV are converted to difference frequency outputs between 0 and 500 KHz, which are then sent to a DCFB or SDC board or PCCA card.

Using DC positive and negative floating shunts, a VCO (voltage controlled oscillator) circuit acts as a conversion point for the voltage.The card also provides 10:1 current transformer attenuation for the AC line current.

The user can select the attenuation using 17 on-board configurable jumpers. If the AC line voltage range is 240 to 600 V, bypass the attenuators. If the voltage range is between 601 and 1000 V, they should be included.
