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 document applies to incoming filters used to control the coupling of signals between the utility area and the consumer area, as illustrated in Figure 1. This document 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. This document applies to incoming filters designed for single or multiphase installations. [Figure 1 - The application of incoming filter]

Signalizacija po nizkonapetostnih električnih napeljavah v frekvenčnem območju od 3 kHz do 148,5 kHz - 4-3. del: Nizkonapetostni ločilni filtri - Vhodni filter
Standard se uporablja za vhodne filtre, ki se jih uporablja za krmiljenje povezovanja signalov med območjem omrežnega napajanja in območjem porabnikov. Standard opredeljuje: minimalno impedanco v ustreznih frekvenčnih pasovih tako na omrežnih napajalnih vratih kot na vratih porabnika, minimalno atenuacijo neželenih signalov, ki se prenašajo iz omrežne napajalne strani do porabnika in obratno. Standard se uporablja za vhodne filtre, ki so zasnovani za eno- ali večfazne inštalacije.

Overview
EN 50065-4-3:2023 - 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 (CLC/CENELEC) specifies requirements for incoming filters that control the coupling of signalling and power-line communication (PLC) signals between the utility area and the consumer area. The standard applies to single- and multiphase installations and defines minimum impedance and attenuation/transfer-function criteria to limit unwanted signal propagation and ensure electromagnetic compatibility (EMC) and safe operation.
Key topics and technical requirements
- Scope: Incoming filters located at the boundary between utility network and consumer network to control coupling of signals (illustrated in Figure 1 of the standard).
- Operating frequency ranges:
- Utility side: 3 kHz to 95 kHz
- Consumer side: 95 kHz to 148.5 kHz
- Impedance minimums (measured per EN 50065-4-1 test methods):
- Consumer port: minimum impedance modulus 5 Ω
- Utility port: minimum impedance modulus 20 Ω
- Filter classification:
- Type 1: meets both utility and consumer impedance requirements
- Type 2: meets only utility impedance requirements
- Type 3: meets only consumer impedance requirements
(Selection should follow local regulations; if none exist, Type 1 is recommended.)
- Transfer function / attenuation: In its operating bands, the filter shall provide the attenuation/transfer characteristics declared by the manufacturer, verified using EN 50065-4-1 test setups.
- EMC immunity: Filters must comply with immunity requirements referenced in EN 50065 parts 2-1, 2-2 (consumer side depending on environment) and 2-3 (utility side).
- Safety: Filters must meet applicable safety requirements outlined in EN 50065-4-2 through EN 50065-4-7.
Applications and stakeholders
- Practical uses:
- Preventing unwanted PLC or signalling leakage between the supply network and customer installations
- Protecting consumer equipment from utility-originated signalling interference
- Enabling reliable mains communication / power-line communication systems while containing emissions
- Who uses this standard:
- Utility operators and distribution network engineers
- Filter and PLC equipment manufacturers and designers
- Test laboratories and conformity assessment bodies
- Installers, consultants, and regulatory authorities concerned with EMC and power-line signalling
