Protect your sensitive electronic equipment from brownouts and overvoltages with APC’s Line-R automatic voltage regulator. Uncorrected voltage fluctuations gradually degrade the life of electronic components, potentially causing premature failure. The Line-R not only adjusts voltages to safe levels, but also provides surge protection against electrical surges and spikes - even lightning. Please note: networking components such as switches, routers, UPS and wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
