The Isolator Series by Belkin featuring Isolated Power Filter Technology (IPF) provides the best surge protection available for your sensitive electronic equipment, against surges, lightning strikes, power distortion and line noise contamination. IPF Technology uses varying power filter levels to isolate and contain power line noise, providing clean power to each device. Its exceptional filter design consists of high-energy Metal Oxide Varistors (MOVs), Differential Isolation Coils and High Frequency Capacitors that are dedicated to each filter level. When devices 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.
