Premier EMI Filters

EMP Filters and HEMP Filters are designed to help reduce electromagnetic pulse energy entering electrical systems through power lines. Critical infrastructure, military installations, government facilities, telecommunications sites, and other mission-critical environments may require specialized protection to help limit the effects of electromagnetic disturbances on connected equipment. A high-altitude electromagnetic pulse (HEMP) can contain three commonly identified components: E1, E2, and E3. These components have different characteristics and can affect electrical and electronic systems in different ways. Selecting appropriate power-line protection is therefore an important part of a broader electromagnetic protection strategy. What Are EMP Filters? EMP Filters are specialized power-line filters designed to attenuate electromagnetic energy conducted through electrical power connections. They are intended for applications where conventional filtering alone may not address the requi...

Electromagnetic pulses can pose a serious threat to electrical and electronic systems by introducing high levels of unwanted energy into connected equipment. Critical infrastructure, communication systems, defense installations, and other sensitive facilities may require specialized protection to reduce the effects of these events. EMP Filters are designed to help control electromagnetic energy entering or leaving a facility through electrical power lines. Unlike conventional EMI filtering, EMP protection can involve much higher-energy transient environments and broader facility-level considerations. Selecting the appropriate filtering technology therefore requires an understanding of the threat, electrical system, and required level of protection. What Are EMP Filters? EMP Filters are specialized power-line filters designed to reduce electromagnetic energy conducted through AC or DC power connections. They are installed at electrical entry points to help prevent unwanted pulse energ...
