The LCR2400 2400W 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) offers three levels of voltage stabilization that correct undervoltages as low as 89V and overvoltages 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 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.Just connect the space-saving NEMA 5-15P right-angle plug with 12' cord to an AC power source, and plug up to 14 devices into the NEMA 5-15R outlets. The outlets are arranged in two isolated filter banks, which use exclusive Isobar technology to prevent mutual interference from causing audio/video distortion, computer lockups or data errors. Front-panel diagnostic LEDs indicate AC power, incoming voltage level and AC line status. The LCR2400 mounts in 3U of standard 19" rack space using the included hardware.
