GE DS2020DACAG1 EX2100 Excitation Controller

The EX2100 Excitation Controller DS2020DACAG1. manufactured by General Electric, is a power module that

It is an AC to DC converter that is powered by 115 VAC. This model typically produces 125 VDC for the model it powers.

Product Description

The primary function of the DS2020DACAG1 is to convert alternating current (AC) power to direct current (DC) power on the DACA power module of the excitation controller.

When you use the DACA module, 115 volts alternating current (VAC) AC power is converted to 125 volts direct current (VDC) DC power.

If a larger power source is required to reliably operate the controller, two DACA modules can be connected to the exciter power distribution model.

The battery power supply and the DACA model will provide 125 VDC of redundant current to the EPDM.

The manual typically used to assist in the installation of this model is the GEH-6632 EX2100 User's Guide, which outlines the operation of devices such as the DS2020DACAG1 model.

To power the controller, the power supply has a nominal voltage of 120 VAC and a maximum a RMS power supply of 10. As long as there is a DACA module connected to the controller you have chosen, this is the correct power supply for the controller.

Whether you are using the simplex control and wiring option or the redundant control system wiring option to the terminal block.

DACA will always direct rectified AC power to the EPDM and then to the coil or GPA power option.

Frequently Asked Questions about the DS2020DACAG1

Does the DACA model have to be connected to the EPDM?

No, according to Figure 2-5 in the GEH-6632 manual.DACA rectified AC is optional.

What is the resulting ground voltage when the DS2020DACAG1 model is connected to an EPDM model and the power input is filtered?

When the input is filtered, the resulting ground voltage will be 62.5 V and -62.5 to the nominal voltage of ground.

Is there a difference between using the DS2020DACAG1 board in simplex control mode or redundant control mode?

No. Regardless of whether the DS2020DACAG1 board is used in simplex or redundant mode, the rectified AC power will always terminate at the supplied GPA power option.

How is the DC generated by the DS2020DACAG1 handled?

As the VDC passes through the DACA model, it couples to multiple other diodes that create a DC bus that feeds the Gate Pulse Amplifier board and many of the control modules.

This module is used as a power control system and helps to convert the AC power on the controller to DC power.
