OhmKat Professional Grade Short Protected 24 Volt Power Supply


Sale price$34.99



  • Will your product work with a Nest E version? I tried a different product from Amazon and I wouldn’t work on Nest E.

    This power supply will work with any thermostat that improves with a C wire installation, including the Nest E.

  • If installed with a Nest Thermostat, which color goes where on the wiring diagram?

    The colors are not important, as there is no polarity.  Either color wire can go into either slot.

  • If I need a longer cord cab I add some wire to it?

    Yes, you can.  If you need a short length, we sell 6ft extensions that attach in the split connection for $9.99. If you need a long run, standard 20 gauge wire will work great.  Depending on the application, we have had successful runs of over 100 feet.  If you have specific questions about your installation, please reach out to service@ohmkat.com and we can help you.
