EATON Power-Suppress 100 ultra-isolator noise suppressors protect sensitive equipment from electrical noise disturbances. Using exclusive double shielding techniques, the Power-Suppress 100 blocks all forms of electrical noise including radio frequency interface(RFI)/electromagnetic interference (EMI), over a broad range of frequencies. Furthermore, the noise suppression is achieved without impeding normal power flow. Power-Suppress 100 ultra-isolator noise suppressors can reduce a 6000 V spike to an insignificant 0.003 V. These high voltage transients contain enough energy to completely destroy the electrical circuit components that are vital to daily operation.
