ALLNET ALL1688PC Powerline fázový spojovač, 3-fázy + neutrál, pasívny, 1-70 MHz, DIN lišta

Electricians and network installers use the ALL1688PC to couple Powerline communication signals across all three phases and neutral in residential and commercial electrical panels. Mounted on a DIN rail, it bridges the phases so that PLC signals from one phase reach devices on another, improving coverage and reliability in three-phase installations.

Why choose it

The passive design requires no external power and introduces minimal signal loss, ensuring efficient coupling without active electronics. Its robust screw terminals accommodate thick conductors, and the DIN rail mounting simplifies installation in distribution boards.

Ideal use cases

• Coupling Powerline signals in three-phase residential or commercial buildings.
• Extending Powerline network coverage across different phases.
• Integrating with HomePlug AV/AV2, G.hn, or IEEE 1901 networks.

Good to know

The coupler operates across a wide frequency range of 1–70 MHz, covering common Powerline communication standards. It is rated for currents up to 63 A per phase, making it suitable for typical household and light commercial installations.
