From individual workstations to secure facilities and command centres, Silicon CPV offers filtering solutions to suit a wide range of operational requirements.
Secure power filtering for critical environments
Silicon CPV provides a comprehensive range of TEMPEST and HEMP filters designed to protect electronic systems from electromagnetic interference (EMI), conducted emissions and high-energy pulse events.
Available in plug-in, inline, rack-mounted and shielded room configurations, these solutions help organisations maintain operational security, meet compliance requirements and protect mission-critical equipment.
Designed for secure operations

Protection solutions for every deployment
From individual workstations to secure facilities and command centres, Silicon CPV offers filtering solutions to suit a wide range of operational requirements.
Simple plug-and-play protection for workstations, communications equipment and deployable systems.
General-purpose TEMPEST filters for secure workstations, communications equipment and deployed systems.
Country and region-specific variants designed to meet local power standards.
Designed for specialist installations requiring industrial connectors and higher-power connections.
High-density TEMPEST-filtered power distribution solutions for racks, control rooms and secure facilities.
Designed to provide TEMPEST protection with additional hardening against High-Altitude Electromagnetic Pulse (HEMP) threats.
Compact HEMP-protected TEMPEST filters designed for individual workstations, communications equipment and deployable systems.
High-performance HEMP-protected filters designed for shielded facilities, SCIFs, command centres and critical infrastructure installations.
High-capacity shielded room TEMPEST filters with HEMP protection, designed for three-phase power systems in mission-critical secure environments.
Purpose-built for secure rooms, SCIFs and shielded facilities requiring controlled power entry points and protection against compromising electromagnetic emissions.
Designed for secure facility installations requiring TEMPEST-compliant power filtering and controlled power entry.
Designed for larger facilities, critical infrastructure and high-load secure installations.
Designed for permanent installation where power circuits require TEMPEST-compliant filtering without power distribution.
Compact inline filters designed to provide TEMPEST-compliant protection for permanent power installations.
Inline filters featuring specialist connectors for industrial, defence and deployable power systems.
19" rack-mounted inline filters designed for secure communications and server environments.
Unlike standard 19" Rack Mount TEMPEST Filters, which distribute filtered power to multiple devices through integrated outlets, Rack Mount Inline TEMPEST Filters are designed to provide dedicated TEMPEST-compliant filtering directly within a power circuit.
Rack-mounted TEMPEST filters that distribute filtered power to multiple devices.
Rack-mounted TEMPEST filters with UK sockets for secure equipment and workstation deployments.
Rack-mounted TEMPEST filters designed for servers, switches and equipment using IEC C13 connections.
High-capacity rack-mounted TEMPEST filters for power-hungry IT, networking and infrastructure equipment.
Silicon CPV TEMPEST filters are designed to support recognised security and compliance standards used within defence and government environments.
