Split Phase Repeater from PulseWorx

The SPR Split-Phase Repeater is a small electronic device that is designed to enhance the communication reliability between devices that use the Universal Powerline Bus (UPB™) method of communication (such as PulseWorx™ devices). It is designed to be used in a typical residential 120/240VAC split-phase electrical environment. The SPR comes in both plug-in and wire-in models. The main purpose of the SPR is to increase powerline communication reliability by taking UPB™ messages transmitted on one phase (leg) of the electrical system and strongly repeating them on to the other phase (leg).
