"The LC1800 1800W 120V power conditioner adjusts under- and overvoltage to provide safe, computer-grade AC power that meets ANSI C84.1 specifications. Built-in automatic voltage regulation (AVR) offers three levels of voltage stabilization that correct undervoltages as low as 89V and overvoltage as high as 147V back to regulated 120V nominal power. Providing optimum Voltage conditions not only extends the life of your equipment, but also keeps also keeps your equipment working through brownouts and prolonged overvoltage conditions.
a network-grade 1440-joule surge suppression rating exceeds the ieee-587 standard for surge suppression (both categories a and B) and prevents even the strongest spikes from inflicting damage, data loss or corruption and audio/video performance problems on your connected equipment. Emi/RFI noise filtering protects your AC line from disruptive electromagnetic and radio interference.
