GE ds2020expsg3 Exciter Power Supply Module 

Part Number ds2020expsg3 Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockDS2020EXPSG3 is an exciter power supply board developed by GE under the EX2000 series. It generates the necessary signals for measuring alternating current and direct current input power. When the supply is powered by the station battery, it also acts as a current limiter. The automatic voltage regulators and excitation systems of the EX2000 series are used in a wide range of turbine-generator applications. 

The EX2000 Excitation Control System is a sophisticated platform for generator excitation. Jumpers JP1 identifies a manually moveable hardware jumper on the EXPS. JP1 connects the Tl secondary's center tap to ground. DS2020EXPSG3 Board Replacement Procedure Switch off the power. To replace the EXPS board, the entire bulk power supply must be removed. Check for zero potential at all power supply assembly connections. To remove the power supply assembly, carefully disconnect the following connectors: Unplug the lFTB, 1TB-8TB, DCTB, VM2A, and VM2B connectors as needed. Disconnect the black and white wires on the CPS PTBl and PTB2 terminal boards. Unplug the ACPL. Remove the power supply assembly from the cabinet by carefully loosening the four assembly mounting screws. ACPL should not be removed. 

Transfer the assembly to a workbench and remove the four screws that hold 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 position 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. The cables are labeled with the connector name as it appears on the board. Reconnect all cables in the order they were removed. Check that the cables are properly seated on both ends. 

 DS2020EXPSG3 Features The board is divided into three major components. A metal base with an attached circuit board, a second metal tier with an attached circuit board, and a plexiglass shield are among them. Each tier's circuit boards communicate with one another via surface-mounted electrical connections. The plexiglass shield is detachable and screws to the surface of the second layer. It has a prominent warning label that warns of the dangers of electrical shock or burns if the device is mistreated. The bottom metal carrier is constructed with two top hat flanges that have each been drilled twice to allow the unit to be readily installed in position. A two-by-two terminal strip is installed in one corner of the metal carrier.

ABOUT THE DS2020EXPSG3

The DS2020EXPSG3 is a power supply module fabricated by GE for use within their Speedtronic Mark V Turbine Control System Series. The Mark V Series that this DS2020EXPSG3 product offering belongs to, as evidenced by the above-attached full extended series name, has specific applications in the control and management systems of compatible and popular wind, gas, or steam turbine automated drive assemblies. While GE no longer manufactures these boards as they exist as a member of a now-obsolete legacy series, they are available through AX Control as reconditioned and fully tested modules. The Mark V Series that this DS2020EXPSG3 Exciter Power Supply Module belongs to is one of the later Mark Series offered by General Electric that features their patented Speedtronic control system technology, with the series being specially applicable to the control and management systems of gas, steam, and wind turbines. The DS2020EXPSG3 Power Supply Module is considered the original Mark V Turbine Control System Series product of its exact functionality to feature in its related automated drive assembly, as no significant product revisions have been made to its assembly.

Hardware Tips and Specifications

The DS2020EXPSG3 is an Exciter Power Supply Module for the EX2000 brushless generator excitation subsystem within the greater Mark V Turbine Control System Series. The DS2020EXPSG3 has three primary sections; these include a large metal base with an attached circuit board, a second metal tier with an attached circuit board, and a plexiglass shield. The circuit boards on each tier of this DS2020EXPSG3 modular assembly communicate with each other via surface mounted wired connections. The plexiglass shield screw mounts to the surface of the second tier of the DS2020EXPSG3 assembly and is removable. It carries a large warning label stating the dangers of electrical shock or burns if the unit is mishandled. The special modular assembly style unique to this DS2020EXPSG3 Power Supply Module is indicated in the DS2020EXPSG3 functional product number through the inclusion of the DS2020 special assembly series tag. Some of the other information revealed in this DS2020EXPSG3 product number includes this DS2020EXPSG3 module's domestic location of original manufacture, its EXPS functional product acronym, its normal style of printed circuit board protective coating, and its group three Mark V Turbine Control System Series grouping.
