UPB Products » UPB 240 Volt Switch
UPB (Universal Powerline Buss) uses power line wiring for signaling and control. Based on the X10 automation standard, UPB provides an improved transmission rate and higher reliability.
UPB addressing allows 250 devices per house and 250 houses per transformer, allowing over 64,000 total device addresses, and switches can co-exist with other powerline carrier systems within the same house.
While UPB may be more efficient than X10, it has far fewer products available on the market.[
