About the DS200DCFBG1AAA

General Electric’s DS200DCFBG1AAA is a power supply board developed for the Mark V board series. The Mark V Turbine Control System Series that this DS200DCFBG1AAA product offering belongs to, as indicated by its full name, has specific applications in the management and control systems of wind, steam, and gas turbine automated drive assemblies, and is considered to exist as a legacy General Electric Mark Series given its eventual manufacturing discontinuation in the years following its initial release. While this DS200DCFBG1AAA product offering's greater Mark V Turbine Control System Series is classifiable as a General Electric legacy series, it is also attributed to be one of the final General Electric product series to feature their patented Speedtronic control system technology. This DS200DCFBG1AAA printed circuit board product offering, while certainly definable as a Power Supply Board in its own right, is more explicitly defined as an edited version of the original DS200DCFBG1 parent printed circuit board, which notable does not make use of this DS200DCFBG1AAA PCB's three A-rated significant product revisions.

Hardware Tips and Specifications

Supplies from this board provide control level power to the unit as well as to the enclosure fan. Drives from the AC2000, CB2000, DC2000, FC2000, and ME2000 can use this board. Members of the EX2000 series can also use this board, but this series interacts differently with the board than drives do. This power supply card sources inputs from the control power transformer rated between 38 and 115 VAC. Depending upon inputted voltages, frequencies for the board can range from 0 to 500 kHz. A number of onboard features allow DS200DCFBG1AAA to provide exceptional user experiences. Circuits found on the board include AC/DC monitoring, driver, motor field power, and control level supply circuits. Configurable system options can be set using the twelve jumpers and seven DIP switches found on board. Two LED status indicators and one neon indicator is featured on the board. Diagnostics regarding various fuse switches on the board are displayed using these indicators. Checking voltage levels on the board is simple using one of the five integrated test points. Protecting the power supply from interruptions is built into the three protective fuses found on the card. These fuses are not the only available piece of voltage-suppressing hardware in this DS200DCFBG1AAA PCB, as it possesses many voltage-limiting hardware components typical of the Mark V Series. These components include various diodes, capacitors, and resistors, as well as the aforementioned integrated circuits in this DS200DCFBG1AAA board's assembly.

The board as well as the drive include installation and storage parameters that must be followed to ensure both operate properly. DS200DCFBG1AAA’s manual and datasheet include complete installation and wiring guidelines for the board. Generally, this DS200DCFBG1AAA PCB should be treated as a static-sensitive printed circuit board that may possess potentially-lethal circuit board surface voltages even after power has been deactivated in its larger Mark V Series automated drive assembly. As indicated by this DS200DCFBG1AAA printed circuit board product offering's original instructional manual, this DS200DCFBG1AAA PCB typically mounts in the Mark V Series drive carrier behind the Mark V Series drive control card. This drive control card typically manifests itself in the form of the Mark V Series' SDCC Drive Control Card, another GE product available in our inventory of new and refurbished Mark V Series circuit boards. General Electric, the manufacturer, was the original provider of technical support for this board. Before making any singular final purchase decision on this DS200DCFBG1AAA product offering, its is important to understand that its originally-introduced dimensions and basic performance specifications have no doubt been altered through its possession of three A-rated product revisions; including two functional product revisions and an artwork configuration revision specifically. Our trusted and friendly sales staff at AX Control is ready to help with all of your DS200DCFBG1AAA and automation needs.

Reviews For DS200DCFBG1AAA

Internal Review

The DCFB board receives 24 VDC power from the CPT. This is full-wave rectified and filtered. The DS200DCFBG1AAA board includes three protective fuses that include indicator lights to let you know when any of the three have been blown. As mentioned before, this DS200DCFBG1AAA PCB's three A-rated product revisions are not identical as they seem, as two styles of revision exist in this DS200DCFBG1AAA Board's assembly. - AX Control Lead Technician
