SPR-3 PulseWorx - Split Phase Repeater - Plug-in 3 Prong NEMA 10-

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).
