Overview - EN 50065-4-5:2003 (Segmentation filter)

EN 50065-4-5:2003 is the CLC/CENELEC European standard for segmentation filters used in mains communication (powerline communication) systems on low-voltage installations. It covers low-voltage decoupling filters that control the coupling of signalling in the frequency range 3 kHz to 148.5 kHz for single- and multiphase installations (phase-to-neutral ≤ 250 V AC, nominal current ≤ 125 A). The standard defines the minimum impedance and minimum attenuation characteristics required at filter ports and sets marking, safety and immunity expectations by reference to other EN 50065 parts.

Key topics and technical requirements

• Scope & application: For household and similar fixed installations including residential, commercial, light industrial buildings and utility networks.
• Filter types:
  • Type 1 - Asymmetrical filter: one supply backbone port and one segment port with differing impedance characteristics.
  • Type 2 - Symmetrical filter: two segment ports with matching impedance characteristics.
• Operating frequency bands:
  • Utility segmentation filters: within 3 kHz to 95 kHz.
  • Consumer segmentation filters: within 95 kHz to 148.5 kHz.
  • The manufacturer must specify the operating frequency range.
• Impedance requirement:
  • On segment ports (type 1 and both ports of type 2): modulus of impedance > 10 Ω across the specified operating frequency range (measurement per EN 50065-4-1 clause 6.1).
• Transfer function / attenuation:
  • The segmentation filter must provide the attenuation specified by the manufacturer, measured in each direction when the filter is loaded with 5 Ω on both sides (measurement methods per EN 50065-4-1 clause 6.2).
• Marking: Must include the operating frequency range and attenuation within these bands.
• Safety & immunity:
  • Overvoltage categories: III for consumer network use, IV for utility network use.
  • Immunity requirements are referenced to EN 50065-2-1, -2-2 or -2-3 depending on environment.

Applications and practical value

• Use segmentation filters to partition a powerline communication system into independent segments to:
  • Reduce interference between building areas or network zones.
  • Improve signal containment and enable multiple PLC networks on the same power infrastructure.
  • Support utility broadband and smart metering deployments where segment isolation is required.
• Typical users: filter manufacturers, PLC system integrators, electrical installers, utility engineers, test laboratories and product certifiers.

Related standards

• EN 50065-1 (general requirements, frequency bands)
• EN 50065-2-1 / 2-2 / 2-3 (immunity requirements)
• EN 50065-4-1 (generic decoupling filter spec) and EN 50065-4-2 (safety)
• Other EN 50065 parts covering incoming, impedance and phase-coupler filters

EN 50065-4-5 is essential for anyone designing, specifying or testing segmentation filters within powerline communication systems to ensure compliant impedance, attenuation and safe operation across the defined signalling frequency ranges.
