Overview The LS604WM 600W 120V Power Conditioner adjusts under- and overvoltages to provide safe, computer-grade AC power that meets ANSI C84.1 specifications. Built-in automatic voltage regulation (AVR) corrects undervoltages as low as 87V and overvoltages as high as 140V back to regulated 120V nominal power. Providing optimum voltage conditions not only extends the life of your equipment, but also keeps your equipment working through brownouts and prolonged overvoltage conditions. A network-grade 720-joule surge suppression rating conforms to the IEEE-587 standard for surge suppression and prevents 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. Just connect the NEMA 5-15P plug with 6-foot cord to an AC power source, and plug up to four devices into the rear NEMA 5-15R outlets. A front-panel LED lets you know your equipment is protected. Secure the LS604WMs all-metal case to a wall or other surface using the built-in mounting tabs and included screws.
