Model DS2020DACAG1
Brand GE
Type excitation controller
The DS200DACAG1A is a MarkV, TC2000, DC2000 AC to DC converter board manufactured by GE(General Electric) as part of its turbine control system.
The DS20ODACAG1A is designed as a component of the GE EX2100 excitation control module. This module provides the excitation current to the generator (gas/steam/hydro) to control its AC terminal voltage and reactive volt-amperes
The modular design of the EX2100 makes it easy to create a system that suits users, whether they need to extract data from compounds, potentials, or secondary sources, or whether they need simplex or redundant control.
DS200DACAG1A boards are no longer manufactured by GE, but can be purchased through AXControl as refurbished/refurbished units or as liquidated never-used parts.
The DS2ODACAG1A is used as an AC/DC converter. It is powered by 115V AC supply and then converted by the components of the board to produce 125V DC output. The board and its corresponding battery source can also provide redundant VDC power to the EPDM power board. If redundancy is required, two DACA boards can be connected to one EPDM.
The EX2100 excitation controller DS2020DACAG1, manufactured by General Electric, is a power module, AC to DC converter, powered by 115VAC. The model typically generates 125 VDC for the model it powers.
The main function of the DS220DACAG1 is to convert the AC power supply on the excitation controller DACA power module to DC power supply. When you use a DACA module, AC power from 115 volts AC (VAC) is converted to DC power from 125 volts DC (NDO).
If a larger power supply is required to operate the controller reliably, two DACA modules can be connected to the exciter distribution model. The battery power supply and DACA model will provide the EPDM with 125VDC redundant current.
The manual commonly used to help install this model is the GEH+-632EX210 User Guide, which Outlines how to operate devices such as the DS220DACAG1 model. When powering your controller, the nominal voltage of the power supply is 120 VAC and the maximum A RMS power supply is 10, as long as the controller you choose is connected to a DACA module, this is the correct controller power supply.
Whether you are using the simplex control and wiring option or the redundant control system wiring option to your terminal board, DACA will always direct the rectified AC power to the EPDM and then to the line or GPA power option.
