Maintains usable 120V nominal output to sensitive electronics during severe brownouts and overvoltages. Prevents surges and spikes from damaging circuitry. Filters out potentially disruptive line noise.

  • Ideal for computers, routers, modems and home theater components
  • Corrects under- and overvoltages in 89V–147V range
  • Protects against spikes with 1200 joules of surge suppression
  • Monitors power status with front-panel diagnostic LEDs
  • Features 4 NEMA 5-15R rear outlets
  • 2-year limited warranty


The LC1200 1200W 120V Line Conditioner - Automatic Voltage Regulator adjusts under- and overvoltages to provide safe, computer-grade AC power that meets ANSI C84.1 specifications. The automatic voltage regulation (AVR) offers three levels of voltage stabilization that corrects 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 1200-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 7-foot (2.1-meter) cord to an AC power source, and plug up to four devices into the NEMA 5-15R outlets. You can monitor AC power, incoming voltage level and AC line status using the seven diagnostic LEDs on the front panel. The compact LC1200 fits comfortably into your computer or home theater setup.

A power or voltage spike is a sudden increase in voltage, ranging from a few hundred volts to tens of thousands and lasting between 1 and 30 microseconds. A power surge is like a spike but lasts longer. Voltage fluctuations are normal and do not typically harm equipment connected to an outlet. Over- or under-voltages occur when the voltage reaching powered devices falls out of the normal service range.
