Ideal for your home or office workstation, this Protect It! 12-outlet surge protector features a surge protection rating of 4320 joules to defend your sensitive electronic components against even the strongest power surges and spikes. Because residential power outlets have three wires - hot line (H), neutral (N) and ground (G) - the TLP128TTUSBB protects all three, covering the two protection modes: full normal mode (H-N) and common mode (N-G/H-G).Plug your PC, printer, scanner, router, modem, television, stereo receiver and other home/office electronics into 12 NEMA 5-15R AC outlets to protect them against dangerous surges, spikes and line noise. Six outlets are designed for greater flexibility in placing connected devices or accepting bulky transformers without blocking adjacent outlets. The eight-foot AC power cord with space-saving right-angle NEMA 5-15P plug helps you connect the surge protector to a wall outlet located behind furniture.Built-in RJ11 jacks and silver coaxial cable connectors allow connection of telephone, fax, modem, cable television and satellite equipment. The TLP128TTUSBB prevents dangerous “back door” power surges from damaging your data line components.Dual USB-A ports are available for charging your smartphone, tablet and other USB mobile devices.Various electromagnetic and radio sources found in virtually every home and business can cause disruptive interference on the AC line. Known as EMI (electromagnetic interference) and RFI (radio frequency interference), this line noise is a common cause of performance problems. This 12-socket surge protector filters out disruptive line noise that can disturb your electronics and inflict hardware damage or data loss. This EMI/RFI filtering also helps your connected components perform better with longer lifespans.The lighted on/off switch provides one-touch control over connected equipment. Diagnostic LEDs confirm your wall outlet is properly grounded and your connected equipment is protected. Its high-impact plastic housing is designed to endure in demanding environments.The TLP128TTUSBB comes with a lifetime warranty and $150,000 of Ultimate Lifetime Insurance for any connected components damaged by a power surge (U.S., Canada and Puerto Rico only). It’s manufactured in compliance with strict RoHS specifications, reflecting Tripp Lite’s commitment to environmental responsibility.
