Tripp Lite Line Stabilizer, 4 Outlets, 1200W, 10A

• Automatic voltage regulation with surge protection

Keeps equipment working through low voltage conditions (brownouts) without using an emergency power source such as a UPS system or auxiliary generator. Will automatically adjust under (as low as 87 volts) and over-voltages (as high as 140 volts) back to a computer-grade 120-volt AC power that meets ANSI C84.1 specifications. Units feature transient over-voltage spike protection and RFI/EMI noise suppression. Models LC1200 and LC1800 also have toroidal balanced chokes for high frequency noise suppression.
