Phase coupler gets UPB signals from one electrical phase to the other
Installs into main circuit breaker panel
The LED on the phase coupler shows that it is working
Are UPB-controlled lights or appliances in one area of your house having trouble receiving signals from UPB transmitters in another area of the house? Because most homes have 2-phase 220V power that splits into two separate 110V legs, sometimes UPB signals have a hard time making the transition from one leg to the other. But connect the HAI UPB Phase Coupler to your main circuit breaker panel, and it will bridge UPB signals between the two power lines in your home easily, allowing virtually all of your UPB receivers to respond to UPB signals.
