Tripp Lite's LR2000 Automatic Voltage Regulation/AVR power conditioner prevents equipment damage, performance problems and system degradation due to voltage fluctuations, line noise and transient surges. Ensures 230V +/-10% output voltage for computer equipment, home theater systems and other sensitive electronic devices during brownouts to 175 and overvoltages to 253V. Reliable transformer-based voltage regulation offers two available levels of voltage boost to correct severe undervoltages, along with a single level of voltage reduction for overvoltages. Network-grade AC surge and EMI/RFI noise suppression removes power contaminants known to cause system interference, lockups and power-related audio and video artifacts. Extends the useful life of connected equipment by enhancing power supply efficiency and preventing overtemperature conditions. Front panel LEDs offer metered verification of input voltage level in 3 stages. Detachable IEC-320 C14 connector accepts a variety of worldwide replacement cordsets. Includes 6 outlets (2 NEMA 5-15R, 2 NEMA 6-15R and 2 IEC-320 C13), plus one UNIPLUG adapter capable of accommodating dozens of international plug types.
