GE BDS200EXPSG1A Bulk Power Supply Board

GE BDS200EXPSG1A Bulk Power Supply Board

Part Number DS200EXPSG1A Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark V Function Module Availability In StockDS200EXPSG1A is a Bulk Power Supply Board manufactured and designed by General Electric as part of the EX2000 Series used in Drive Systems. The right signals are supplied by the EXPS to measure both ac and dc input power. When the supply is activated using the station battery, it also offers a current-limiting action. The base number used to identify a printed wiring board, specifically the EXPS, is DS2OOEXPS. The board revision level is denoted by the alphabetic characters I and u in the numerals. The r digit indicates a change in functionality that is not downward compatible. 

In essence, it is a brand-new catalog number. Revision levels that are downward compatible are represented by the II digits. A group, which is a specific board variation, is identified by the G#. FEATURES: All of the components on the board are protected by the three fuses on the board from over-voltage and other irregular voltage conditions. If there is too much voltage in the circuit, the element within the fuse will melt. In that event, the circuit in which the fuse is located will shut down, electricity will be cut off, and all components will be safeguarded from the voltage. If the fuse blows, however, the servicer must establish the cause of the overvoltage problem and replace the fuse. Consult an engineer or other competent people if you are unfamiliar with the electrical supply used by the drive. The fuses' ratings can be found in the printed literature that came with the board. 

It's critical that you only use fuses of the same rating when replacing them. Another rating fuse could expose the components to voltage, which could destroy the board if the components are exposed to too much voltage. Remove power from the drive once you're sure the over-voltage situation has been handled. BOARD REPLACEMENT PROCEDURE: To replace the EXPS board, the full bulk power supply must be removed. Check for zero potential at all power supply assembly connections. To remove the power supply assembly, carefully unhook the following connectors: Unplug the LFTB, 1TB-8TB, DCTB, VM2A, and VM2B connectors as needed. Unplug the black and white wires from the CPS PTBl and PTB2 terminal boards. Unplug the ACPL. 

 Remove the power supply assembly from the cabinet by loosening the four assembly mounting screws. ACPL should not be removed. Transfer the assembly to a workstation and remove the four screws that keep the plastic protective cover in place. Unplug the DCPL, 3GDPL, and 4GDPL connectors from the EXPS board. Replace the old EXPS board with the new EXPS board. Set JPL on the replacement (new) board to the same location as on the board being replaced (old board). Reconnect the connectors that were removed in step 5. Replace the protective plastic cover and screws. Replace the power supply assembly in the cabinet. Reconnect the connectors that were removed in step 3.

This DS200EXPSG1A Mark V Series printed circuit board, as alluded to earlier, is a crucial member of its greater Mark V Turbine Control System Series automated drive assembly. This EXPS-abbreviated printed circuit board exists as a Bulk Power Supply Board, as this is the functional description that it is referred to by in original Mark V Series and broader General Electric instructional manual materials. While this DS200EXPSG1A printed circuit board or PCB does exists as a Bulk Power Supply Board with a normal style of Mark V Turbine Control System Series assembly, this DS200EXPSG1A PCB is not the original Bulk Power Supply Board that was produced for the Mark V Series, as the DS200EXPSG1 parent circuit board exists without this DS200EXPSG1A product offering's added functional product revision.

Hardware Tips and Specifications

This DS200EXPSG1A Bulk Power Supply Board is a well-documented product in terms of its original instructional manual materials that are available for research purposes on the internet. The GE Power Supply Board DS200EXPSG1A features one reset button, 3 fuses, and 1 LED. The GE Power Supply Board DS200EXPSG1A also is populated with 3 9-pin connectors, multiple capacitors, and test points. The 3 fuses on the DS200EXPSG1A board serve to protect all of the components on the board from over-voltage situations as well as other irregular voltage conditions; as the element inside the fuse will melt if too much voltage is present in the circuit. In that case, the circuit the fuse is part of will cease operation, power will stop entering the circuit, and all components will be protected from the voltage condition. However, if the fuse blows, the servicer must determine the cause of the over voltage condition and the fuse must be replaced. If you are not familiar with the electrical supply used with the drive, consult with an engineer or other knowledgeable individual; the base circuit board of this DS200EXPSG1A product is extremely voltage-sensitive and will be damaged during incorrect installation attempts.

One manually-moveable hardware jumper is present in the assembly of this DS200EXPSG1A Mark V Series product offering, as revealed once more in pertinent General Electric instructional manual materials. This hardware jumper is accompanied by the standardized J1 diagnostic reference designator, and connects the second tap of this DS200EXPSG1A Bulk Power Supply Board's T1 secondary to the ground. This DS200EXPSG1A Bulk Power Supply Board is classifiable as a relatively fragile and voltage-sensitive printed circuit board within the Mark V Series, given the low amount of hardware components on its base circuit board. Luckily enough, most to all of the individual hardware components included in the assembly of this EXPS-abbreviated PCB should receive some basis of rudimentary protection from this DS200EXPSG1A printed circuit board's normal style of printed circuit board protective coating. All of the factory-drilled installation holes available to the assembly of this DS200EXPSG1A Bulk Power Supply Board should be insulated in recognition of the potential presence of damaging static electricity and surface voltages.
