Description

Details

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.

When installed, DS200SHVMG1A provides an array of functions to the drive. 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.

Any manufacturer provided installation parameters for both the drive and the board should be met. Following these guidelines ensures that the entire drive system operates as required.

The series manual as well as the device datasheet contains a complete wiring and installation guide. DS200SHVMG1A as well as the entire Mark V series was originally provided technical support by the manufacturer, General Electric.
