FUNCTIONAL DESCRIPTION:

DS200TCPSG1ARE is a DC Input Power Supply Board manufactured and designed by General Electric as part of the LM2500 Series used in GE Aeroderivative Gas Turbine Control Systems. The Power Supply Board (TCPS) is located in and each of the four IO cores converts 125 V dc power from to the voltage levels required. These include, but are not limited to such things as, microprocessor power supply voltages, mA output power supply voltages, RTD power supply voltages, and servo valve current outputs.

TCPS CONNECTORS:

2PL - Distributes the power supply voltages to the various boards in a daisy chain fashion.
J1 - Connector that brings in the 125 V dc power into the TCPS board from the TCPD board in the core.
JC - Distributes power supply voltages for the power supply diagnostics on the TCQC board in cores , , and and the TCCA board in the core.
JP1 - Distributes power supply voltages to the TCDA board in the digital cores , and and to the AAHA boards in the core.
JP2 - Same as JP1. Either JP1 or JP2 could be used. X1 - CCOM bus connection.
TB2 - Four-point terminal board for setting contact input excitation to either 24V dc or 125VC.

TCPS CONFIGURATION:

The IO boards in the Mark V LM controller are configured using a combination of hardware jumpers and software. Many boards in the Mark V LM controller have hardware jumpers for enabling or scaling input and output functions. Appendix A describes the hardware jumper settings, while the signal flow diagrams in Appendix D show how they affect input and output circuits.

I/O BOARD SOFTWARE CONFIGURATION:

The IO boards are programmed to scale and condition IO signals using firmware contained in EEPROM and configuration data stored in RAM. The IO configuration for all boards associated with a specific IO Engine is loaded during every re-boot/startup of their corresponding IO Engine. Each IO Engine receives configuration data from the Control Engine in the core. The Control Engine maintains the data until changed by a download from the operator interface over the Stage Link. The user sets IO configuration data using the I/O Configuration Editor from the operator interface.

FREQUENTLY ASKED QUESTIONS:

What is the difference between AC and DC input in a power supply?

AC (Alternating Current) input refers to the type of electrical power commonly delivered by power grids, where the direction of current alternates. DC (Direct Current) input, on the other hand, provides a constant flow of current in one direction. DC is typically required for the operation of most electronic devices, which is why AC is converted into DC by the power supply board.

What is the role of the transformer in a DC Input Power Supply Board?

The transformer in a DC Input Power Supply Board is responsible for stepping down the input AC voltage to a lower level that is more suitable for the connected devices. The transformer achieves this by using two or more coils of wire to create a magnetic field that induces a lower voltage in the secondary coil. This lower voltage is then rectified to DC by the rest of the power supply circuitry.

How do I calculate the output voltage of a DC power supply?

The output voltage of a DC power supply depends on the design and components of the circuit. If you're using a transformer, the output voltage is determined by the turn ratio of the transformer. For regulated supplies, the output voltage is set by the voltage regulator. If the board uses a buck or boost converter, the output voltage is determined by the conversion factor.
