APC Line-R 1200VA. Automatic voltage regulator ( external ). 1200 VA. 4 output connector(s). The Line-R is a microprocessor controlled tap changing power conditioner, which automatically corrects brownouts and overvoltages, and stabilizes chronic line voltage variation. Line-R also provides multi-stage surge suppression and full-time EMI/RFI filters to handle all the problems your equipment is likely to face. A voltage meter on the Line-R's front panel displays the relative input voltage level and alerts you to low or high voltage conditions. A front panel surge protection integrity light indicates the health of the circuitry. Besides correcting dangerous voltage fluctuations, these units offer one of the highest Energy Surge Rating around, which is important to protect against the most harmful disturbances in your AC line called spikes.
