AUTOMATIC VOLTAGE REGULATOR(AVR) 
The PR3000ELCDRT2U can stabiliz the consistent utility power. The utility power 
may be damaging to important data and hardware, but Automatic Voltage 
Regulation helps the computer not experience dangerous voltage levels. 
Automatic Voltage Regulator automatically regulates low or high voltages to keep 
equipment working at safe AC power levels (220/230/240V) without switching to 
battery. Your equipment can operate normally even meet the power problems, 
such as, shout brownouts and blackouts. The unit’s powerful sealed lead-acid 
batteries will provide power only if the incoming voltage drops below 150V or 
increases above 300V.

device (Hard drive, Tape drive, etc.) into the outlets. DO NOT plug a laser printer, copier, space heater, 
vacuum, paper shredder or other large electrical device into the UPS. The power demands of these devices will 
overload and possibly damage the unit.
