SIST EN 50065-4-3:2004

Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz -- Part 4-3: Low voltage decoupling filter - Incoming filter

This standard applies to incoming filters used to control the coupling of signals between the utility area and the consumer area (see Figure 1).
The standard defines
•   the minimum impedance in the relevant frequency band(s) at both Utility port and Consumer port,
•   the minimum attenuation of unwanted signals transmitted from the utility side to the consumer side and vice versa,
•   the transmission characteristics:
-   operating frequency domain for both utility side and consumer side,
-   attenuation between the utility side and the consumer side and vice versa,
-   impedance at the utility side and at the consumer side.
This standard applies to incoming filters designed for and used in single or multiphase installations.

Overview

EN 50065-4-3:2003 is the CLC (CENELEC) standard for incoming low-voltage decoupling filters used to control the coupling of signalling between the utility area and the consumer area on low-voltage electrical installations in the frequency range 3 kHz to 148.5 kHz. It specifies electrical characteristics, minimum impedance and attenuation requirements, operating frequency domains and test conditions for single- and multiphase installations.

Key topics and technical requirements

• Scope
  • Applies to incoming filters that separate utility and consumer networks for signalling on low-voltage installations.
  • Covers impedance, attenuation and transmission characteristics in both directions (utility → consumer and consumer → utility).
• Operating frequency ranges
  • Utility side: 3 kHz to 95 kHz
  • Consumer side: 95 kHz to 148.5 kHz
• Filter classification
  • Type 1: Meets both utility and consumer impedance requirements (default where no local rule exists).
  • Type 2: Meets utility-side impedance only.
  • Type 3: Meets consumer-side impedance only.
• Impedance and transfer function
  • Minimum impedance modulus values defined for each side and measured per EN 50065-4-1 test methods.
  • Transfer function (attenuation) requirements are set within the operating band(s) and measured with the opposite side loaded (typically 5 Ω), with marked operating band and attenuation specified by the manufacturer.
  • Test loads include resistive RL values: 1 Ω, 5 Ω, 10 Ω, 20 Ω, 50 Ω and open circuit.
• EMC and overvoltage
  • EMC requirements reference EN 50065-2-1 / 2-2 / 2-3 depending on environment (residential, commercial, light industrial or utility).
  • Overvoltage categories: utility side Category IV, consumer side Category III.
• Test setup details
  • Test configuration illustrated (e.g., air-core inductance L = 125 µH, C ≥ 100 µF) and forbidden/no-coupling zones are defined for impedance characteristics.

Applications and who uses this standard

• Manufacturers of incoming/decoupling filters and mains communications equipment.
• Utility engineers and electricity distributors specifying filter performance between network and consumer premises.
• EMC labs and test houses performing conformity testing and type approval.
• System integrators and installers deploying signalling over low-voltage networks (mains communicating systems) in residential, commercial or industrial installations.
