Power Line Filter

Aids in error free data in all three bands.  Unlike most filters designed only for the 120kHz X-10 band.

 

Why a Power Line Filter?

There are many methods of sending data down the power wires in your house or business.

X-10 uses 120kHz tones synchronized with the 50 or 60Hz power.

Power Lime Modem 100kHz to 400kHz

Ethernet Power-Line Bridge 4.3 to 20.9mHz
