Product Description

The function of the DS2020DACAG2 module is to convert a VAC power supply to a VDC power supply. After the power supply has been converted to 125 VDC a diode will be coupled to the other DC sources within the controller to create a DC bus that will then feed any of the controller modules as well as the gate pulse amplifier boards connected to the module. 

The outputs, such as the EPDM, EGPA, EXTV, and EPBP that are connected to the DACA module all have LED indicators which will indicate the proper power being supplied to the DS2020DACAG2. It is important to note that when the diodes have been coupled together and the ground of the model centered the grounded voltages of your device should nominally read +62.5 and -62.5 volts. 

The manuals that are best used when operating the DACA device are the GEH-6632 EX2100 User’s Guide and the GEH-6721L PDM Power Distribution Modules System Guide. 

The DS2020DACAG2 module is a backward compatible system and should be used as a replacement part for the DS2020DACAG1 module. When one or potentially two DACA modules have been connected to the IS2020JPDF the AC current will be provided through a wire harness that is located between JPDF and JPDB.

Please advise that when using two parallel DACA modules they are connected to the same AC supply to ensure that the DACAs are receiving equal input voltages. 

Frequently Asked Questions about DS2020DACAG2

There is a DS2020DACAG1 model, is there any difference between the previous model and the DS2020DACAG2 model?

No, there are virtually no differences between the DS2020DACAG1 and DS2020DACAG2 models. The two models can be connected to provide a greater power supply for the Exciter Power Distribution Module (EPDM).

Within the GEH-6632 EX2100 Excitation Control User's Guide where can I find the most information on the DS2020DACAG2 model?

The best place to look for information on the DS2020DACAG2 within the GEH-6632 manual is Chapter Three, which is an overview of the Printing Wiring Boards, 3-9 is the start of information on the Power Supply Boards, 3-10 is where much of the information about the DACA modules reside. 

If the DS2020DACAG2 module is used at an ambient temperature of one-hundred and forty-nine degrees Fahrenheit when should it be replaced?

Models used at one-hundred and forty-nine degrees Fahrenheit should be replaced about every five years due to the wear out of the Electrolytic Capacitor.

If two DS2020DACAG2 units are connected can they each be connected to a different ac source?

No, if two DS2020DACAG2 models are being connected they need to be connected to the same ac source to ensure equal input voltages.
