The Isolator Series by Belkin features Isolated Power Filter Technology (IPF) which provides top surge protection for your sensitive electronic equipment. The Isolator Cable Kit provides protections against surges, lightning strikes, power distortion and line noise contamination.
Its exceptional filter design consists of high-energy Metal Oxide Varistors (MOVs), Differential Isolation Coils and High Frequency Capacitors that are fitted to each filter level. When peripherals such as a printer or scanner are used, every filter works together to ensure that you will not experience computer lockups, data loss, audio static, or video interference.
