The SRA-2000 is a compact rack mount ups that also provides power line surge protection. From the Manufacturer: The SRA Series of battery backup UPS models feature value priced yet feature rich UPS technology incorporating automatic voltage regulation (line interactive) function that preserves battery power and supports sensitive electronic equipment during brown outs. Once incoming voltage drops below operational levels, SRA switches to battery to maintain power continuity. These products also provide 960 Joules of power line surge protection Features: Voltage Regulation Provides support during low voltage sags. When utility power ranges between 90 and 150 VAC, voltage output stabilizes between 103 and 136 VAC.  Line Interactive circuitry monitors the incoming voltage level and routes current through the appropriate taps on a buck/boost transformer to raise or lower output voltage, improving the performance of powered equipment and extending the usable range of the utility power before switching to battery mode.
