Powerline coupler ALLNET INTD ALL168x 3-phase passive – ALLNET KC002-923/271-500

The ALLNET INTD ALL168x 3-phase passive powerline coupler is designed to join or route powerline communication signals across three-phase electrical installations without requiring an external power supply. As a passive device, it provides galvanic coupling and controlled attenuation between phases to enable data transmission over existing wiring in residential, multi-dwelling or commercial environments. The unit is intended for integration into distribution panels or junction boxes where phase-to-phase signal transfer or isolation is needed while maintaining line integrity for mains power.

Advantages

The passive design eliminates the need for a local power source and reduces points of failure. The coupler offers consistent impedance characteristics and low insertion loss to support stable powerline communication performance. Its form factor and mounting options allow installation within standard electrical enclosures, and the device works without active signal regeneration, which reduces maintenance and compatibility concerns with a variety of powerline adapters and modems.

Suitable for

• Extending powerline communication across three-phase distribution in homes and apartments
• Integrating powerline networking in commercial buildings and offices with multi-phase mains
• Linking separate phase circuits in distribution panels to improve signal reach for PLC devices
• Use in retrofit installations where running new data cabling is impractical

Key specifications

• Passive, three-phase coupling topology
• No external power required
• Designed for integration into electrical distribution panels or junction boxes
• Low insertion loss and controlled impedance for powerline communication bands
• Suitable for use with common powerline communication standards and adapters
• Compact form factor for in-cabinet mounting

How to use

Install the coupler in the distribution panel or designated junction box following local electrical regulations and safety practices. Connect the device between the phase conductors as required for your installation, ensuring secure terminations and proper isolation from live parts during installation. Because the unit is passive, no configuration or power connection is necessary; once wired, it will provide the intended phase coupling for powerline communication equipment already connected to the network. Confirm correct operation of powerline adapters after installation by testing data connectivity across phases.

Recommendations

Place the coupler where it is protected from moisture and mechanical damage, and ensure installation is performed by a qualified electrician. For optimal powerline communication performance, combine the coupler with properly installed outlets, surge protection, and minimized noisy loads on the mains. Verify that local codes permit passive coupling and that any residual interference is evaluated during commissioning.
