It converts 115\/230 VAC input power into a DC supply for power distribution within the EX2100 excitation control system. The module has a rated output power of 1000 W and supports a maximum output current of 9.5 A DC per module.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe DS2020DACAG2 converts incoming AC power into DC power for the excitation control system's internal power distribution. In the GE EX2100 architecture, the DACA supplies the Exciter Power Distribution Module (EPDM), which distributes DC power to the control, I\/O, and protection circuits.\u003c\/p\u003e\n\u003cp\u003eThe converted DC supply is diode-coupled with other available DC sources, including the station battery supply. This arrangement allows multiple power sources to contribute to the common DC supply bus without directly connecting their outputs together.\u003c\/p\u003e\n\u003ch3\u003ePower Conversion and Distribution\u003c\/h3\u003e\n\u003cp\u003eThe module provides up to 1000 W of output power, with a maximum output current of 9.5 A DC for a single DACA module. Its DC output supports the nominal 125 VDC power distribution architecture used by the EX2100 excitation system.\u003c\/p\u003e\n\u003cp\u003eThe EX2100 system documentation describes the use of two DACA modules connected to the EPDM when additional power supply redundancy is required. The actual system configuration depends on the installed power distribution arrangement.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eDS2020DACAG2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAC\/DC Power Conversion Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunctional Acronym\u003c\/td\u003e\n\u003ctd\u003eDACA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage\u003c\/td\u003e\n\u003ctd\u003e115\/230 VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e126 VDC (as specified in supplied product data)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Distribution Voltage\u003c\/td\u003e\n\u003ctd\u003e125 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Power Rating\u003c\/td\u003e\n\u003ctd\u003e1000 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Output Current\u003c\/td\u003e\n\u003ctd\u003e9.5 A DC (single DACA module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCapacitor Type\u003c\/td\u003e\n\u003ctd\u003eElectrolytic Capacitors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-22 to +140 deg F (free convection)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e5 to 95%, non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLife Expectancy\u003c\/td\u003e\n\u003ctd\u003e100 years at an ambient temperature of 68 deg F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eEnvironmental and Component Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe DS2020DACAG2 is specified for operation under free-convection cooling conditions, with a temperature range of -22 to +140 deg F and relative humidity between 5% and 95%, non-condensing.\u003c\/p\u003e\n\u003cp\u003eThe assembly uses electrolytic capacitors in its power conversion circuitry.
