Product Description

The prime function of the DS2020DACAG1 is to convert the alternating current (AC) power source to the direct current (DC) power source on the Excitation Controller DACA power supply module. As you are using the DACA module the AC power supply of 115 volts of alternating current (VAC) will be converted to a DC power supply of 125 volts of directing current (VDC). 

Two DACA modules can be connected to an exciter power distribution model if a greater power supply is needed to reliably operate the controller. A battery source and the DACA model will provide a redundant current of 125 VDC for the EPDM. 

The manual commonly used to help install this model is the GEH-6632 EX2100 User’s Guide, this guide gives a general overview of the way that the equipment such as the DS2020DACAG1 model will operate. When powering your controller the power will have a nominal 120 VAC and a maximum A RMS supply of ten this will be the correct controller power as long as there is one DACA module attached to the controller of your choice. 

Regardless if you are using a simplex control and cabling option or a redundant control system cabling option to your terminal board the DACA will always direct the rectified AC power will be directed to the EPDM which will then direct to a coil or GPA power option. 

Frequently Asked Questions about DS2020DACAG1

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

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

When the DS2020DACAG1 model is connected to the EPDM model and supply inputs are filtered through what are the resulting grounded voltages?

After the inputs have been filtered the resulting ground voltages will be a nominal voltage of +62.5 V and -62.5 to ground. 

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

No, regardless of the DS2020DACAG1 board being used in simplex or redundant mode the rectified AC power will always end up at the GPA power option provided. 

How is the resulting DC from the DS2020DACAG1 handled?

When the VDC has been passed through the DACA model it will then be coupled with multiple other diodes that create a DC bus to feed the gate pulse amplifier boards and numerous control modules. 

Reviews For DS2020DACAG1

Internal Review

This module functions as a power control system that will help convert the AC power source to a DC power source on your controller. This model cannot be used for parallelling and has been replaced by the DS2020DACAG2 module. - AX Control Technician
