Product Description
General Electric’s DS200SHVMG1AED is an SCR High Voltage M-frame interface board; this card was developed for the Mark V series of optional and replacement boards. As a member of that series, this interface board can easily be installed across a wide range of GE brand drives and exciters. After installing the card, a medium for interfacing the SCR bridge from the M-frame drive and the power supplies found in either the DCFB or SDCI board as well as the power connect card, or PCCA.
A number of voltage and conversion functions are provided by installing this board into a drive. Differential frequency outputs ranging from 0 to 500 kHz are produced by the card converting shunt signals ranging between -500 and 500 mV. All conversions of these signals are performed by DC positive and negative floating shunts in the voltage-controlled oscillator (VCO) circuits. Once converted, the differential frequency outputs are sent to the DCFB/SDCI board or the PCCA card. AC line currents on the board are provided a 10:1 current transformer attenuation. There are 17 configurable jumpers on board, allowing users to select attenuation rates.
Installation parameters provided with the DS200SHVMG1AED as well as the installing drive should be followed. Meeting these guidelines will protect the drive system from any accidental or avoidable damages. Instructions for installing the board and wiring all the components are available in the device’s manual and datasheet. Members of the Mark V series of boards were originally provided with technical support by General Electric, the manufacturer.
