FUNCTIONAL DESCRIPTION:

IS200DACBG1ABC is an AC/DC Converter Power Supply Module manufactured and designed by General Electric as part of the EX2100 Series used in GE Excitation Control Systems. Some EX2100 exciters may contain DACBG1ABC power supply modules. An AC/DC Converter Power Supply Module is an electronic device used to convert alternating current (AC) voltage from a mains power supply into direct current (DC) voltage suitable for powering electronic circuits or devices. These modules are commonly used in various applications where stable and reliable DC power is required. Both DACBG1ABC modules can supply power to M1, M2, or C controllers. The power source for the DACBG1ABC modules does not have a separate switch within the EX2100. Voltage must be measured at the terminal board to verify that the external power source to the DACB module is OFF.

INSTALLATION:

• Verify that the DACBG1ABC is redundant and that the external disconnect switch for the one being replaced is OFF.
• Verify that all connectors/cables to the DACB are correctly labeled, then disconnect them.
• Remove the mounting hardware that secures the module in place, then remove the DACB.
• Orient the new DACBG1ABC in the same position as the one removed, then set it into place.
• Secure the new DACBG1ABC with the mounting hardware removed in step 3, then tighten per the table Torque Requirements for General Hardware.
• Important: The connector from the DACB transformer must be plugged into the socket on the DACBG1ABC faceplate that matches the voltage level (115 or 220 V ac) of the control power source. Verify this connection per the external power source to the DACB from the EPDM. An input of 220 V ac requires EPDM, Rev B, or later.

• Reconnect all connectors/cables that were disconnected in step 2 and tighten cable connections per the table Torque Requirements for General Hardware.
• Perform any necessary hardware verifications and tests per the applicable procedure in the EX2100 Installation and Startup Guide.

OPERATION:

The AC/DC Converter Power Supply Module, particularly the DACBG1ABC module used in the EX2100 Excitation Control System, operates by converting alternating current (AC) from an external mains source into a stable, regulated direct current (DC) output. The module accepts an AC input, typically in the range of 120–240 VAC at 50/60 Hz. This input first passes through EMI filters and surge protection circuits to eliminate electrical noise and shield the module from power surges. The filtered AC voltage is then rectified into high-voltage DC, which is further processed through high-frequency switching circuits. Using Pulse Width Modulation (PWM), the module regulates and converts the voltage to the desired output level, commonly 24V, 48V, or 125V DC, depending on the system requirements.

The DACBG1ABC module is also equipped with built-in protection features such as overvoltage, overcurrent, and thermal shutdown to safeguard the connected components and itself. These modules often include visual indicators like LEDs to show operational status or faults. It is important to note that the DACB module does not have a built-in power switch within the EX2100 system. Therefore, technicians must verify that the external power supply is disconnected by measuring voltage at the terminal board before performing any maintenance. This operational design ensures both continuous performance and safety in high-reliability applications like generator excitation systems.
