FUNCTIONAL DESCRIPTION:

DS200DACAG1ACC is an AC to DC Power Conversion Module manufactured and designed by General Electric as part of the Mark V Series used in GE Speedtronic Gas Turbine Control Systems. The DS2020DACAG2 is a drop-in replacement for the DS2020DACAG1. It is backward compatible in systems that used the previous version, and it should be used as a replacement part for the previous model. The DACA converts 115/230 V ac input power into 125 V dc output power, and the output power rating is approximately 1000 W. A DACA is used when the primary power source for a control system is 125 V dc with or without a battery. In addition to power conversion, DACA provides additional local energy storage to extend the ride-through time whenever the Mark V Control has a complete loss of control power. Also, this new model can be paralleled for greater output current, whereas paralleling was not recommended for the previous model.

INSTALLATION:

The DACA module has four mounting holes in its base. AC power input and DC output are through a single 12-position connector JZ that is wired into connector JZ2 or JZ3 of the PDM. Selection of 115 V ac or 230 V ac input is made by plugging the DACA internal cable into connector JTX1 for 115 V or JTX2 for 230 V.

DACA FILTER CAPACITOR WEAR OUT:

• Remove power from the DACA module. Allow 1 minute for the output voltage to discharge.
• Remove the power input/output cable (JZ) on the right side of the module top.
• Remove the four bolts securing the DACA module to the floor of the cabinet.
• Remove the DACA module.
• Make note of which receptacle the capacitor power plug is in. This is on the left side of the module's top. JTX1 is for 115 V ac, and JTX2 is for 230 V ac.
• Ensure the capacitor power plug is in the same position as the one removed. JTX1 is for 115 V a,c, and JTX2 is for 230 V.
• Place the new DACA module in the same position as the one removed.
• Secure the DACA module to the cabinet floor with the four bolts removed from the previous module.
• 9 Install the power input/output plug (JZ) on the right side of the module top.

The electrolytic capacitors in the DACA module wear out over time due to the ambient temperature of the environment where they are used. The following table shows the calculated life expectancy and recommended replacement schedule for the DACA modules.

OPERATION:

• DACA receives AC power through the cable harness that is plugged into connector JZ. DACA uses a full-wave bridge rectifier and an output filter capacitor. If needed, the user must provide an input filter to attenuate harmonic currents injected into the incoming line.
• The DACAs must be connected to the same AC source to ensure equal input voltages to the DACAs.
• The maximum output current per DACA is derated for parallel operation. This derating accounts for the variance in DACA open circuit voltages and the variance in DACA output impedances. The following curve should be used. The maximum recommended total panel current is 16.5 A DC.

FREQUENTLY ASKED QUESTIONS:

What is the output voltage of an AC to DC power conversion module?

The output voltage depends on the design of the module. Common output voltages are 5V, 12V, 24V, and 48V DC, but custom modules can be designed for different voltages based on specific requirements.

Can an AC to DC converter handle all types of AC inputs?

Most AC to DC converters can handle a wide range of AC input voltages, such as 110V, 220V, or 380V, but it's important to choose a module that matches your specific AC input voltage.

What is the efficiency of an AC-to-DC power conversion module?

The efficiency can vary depending on the quality and design of the module. Typical efficiencies range from 80% to 95%. Higher efficiency means less energy loss in the form of heat.
