Product Introduction

The DS200DCFBG1BLC is a power board designed by General Electric for the Mark V series optional and replacement boards. Members of this family are cross-compatible with many GE brand exciters and drives. The DC2000, AC2000, CB2000, ME2000, and FC2000 drives can all accept this power board. This card provides system control level power to the drive to which it is installed, as well as providing power for the cabinet fans. The AC input source rating for this board is 38 to 115 VAC. The frequency range that accompanies this VAC is 0 to 500 kHz, depending on the strength of the input voltage. While this DS200DCFBG1BLC printed circuit board itself can be defined as a power board, the original power board developed in the Mark V turbine control system family was the DS200DCFBG1 power board, which lacks three important functional revisions of this DS200DCFBG1BLC product. As its extended name implies, this DS200DCFBG1BLC power board's larger Mark V Turbine Control System family has specific applications in the management and control systems of wind, steam and gas turbine automated drive components.

The card includes AC and DC monitoring circuits, control stage power supply circuits, motor excitation power supply circuits, and drive circuits. The user can configure the twelve jumpers and seven DIP switches on the card to meet any external requirements. The board status is communicated to the user through onboard indicators. Two LED indicators and a neon indicator are built into the card to provide the user with important diagnostic and status information. The board's three fuses are protected, ensuring that any major interruptions or surges will not disrupt the flow of current on the DS200DCFBG1BLC board or its larger Mark V Series AutoDrive components. Be sure to monitor voltage levels regularly using the board's five integrated test points. Fortunately, the specific function of each of the DS200DCFBG1BLC product's five test points is described in the DS200DCFBG1BLC instruction manual embedded in the Manuals tab above. The test points for this DS200DCFBG1BLC power board include:

P5 +5 V DC power test point
DCOM 0 V test signal common reference point
P15 +15 V DC power test point
N15 -15 V DC power test point
ACCT DCFB to SDCC ACCT signal test point
All of the above test points in this DS200DCFBG1BLC board assembly are named by their factory printed naming labels, specific voltage ratings, and functional combinations of the DS200DCFBG1BLC printed circuit board and its larger Mark V Turbine Control System Series automated drive assembly. The DCFB and SDCC boards accessed by the ACCT test points for this DS200DCFBG1BLC product can also be purchased and serviced here in a variety of different revisions. It is critical that the installation parameters provided with the DS200DCFBG1BLC and drive are followed. These guidelines will ensure that the board and the system it is installed in will operate as expected. In general, this DS200DCFBG1BLC printed circuit board should be considered an electrostatically sensitive product that may have lethal surface voltages during or after normal functional use. Refer to the series manual as well as the device datasheet for wiring and installation guidelines. Technical support for all Mark V Series boards is initially provided by the manufacturer, General Electric. The trusted team at AX Control is happy to help you with all of your DS200DCFBG1BLC needs.
