Allowed me to install my Ecobee 3 where previously I had an older POE powered thermostat and no C wire from my heating system.

My last AC transformer was way under voltage, this one fixed my doorbell. Running this over 50ft of 18 gauge (new) & 75ft of cat-3 cable (old) joined together to power a Ubiquiti G4 Doorbell pro. Works great :-)This transformer is sold as 24VAC but actually outputs 29VAC when measured by multimeter.The doorbell is working great since installing, but took one star off for being over 10% out of spec. Buyer beware, this could destroy poorly built electronics that can’t handle a little more than 24V

I use it to test 24v AC relays had 5. Hook the relays up and if I heard a click I knew it was a good one.

I bought this because the transformer for our current doorbell, hung "conveniently" waaaay up in the attic, was only about 12 volts (according to my multimeter). The Arlo Video Doorbell will NOT work with a 12 volt transformer, it requires a 24 volt transformer.1) I bought 18/2 wire at Home Depot for the installation2) the transformer comes with a bolt in it. That didn't work for me as the outlet I needed to use is a GFCI outlet which doesn't have a middle bolt hole, so I had to use a small (6 inch) extension cord from the GFCI outlet to the transformer. The bolt on this transformer is NOT easily removeable as the housing of the transformer blocks the bolt's removal. If your outlet doesn't have have a spot for the bolt, you will need a workaround like I used.3) the Arlo Video Doorbell has specific instructions for using a plug-in transformer instead of the transformer found in my attic. You MUST, and I quote, "select None as the Traditional Chime option to avoid any damage to your plug-in AC power adapter".4) this plug-in transformer will not require the Power Kit that comes with the Arlo Video Doorbell unless you use a chime along with the Video Doorbell.

I bought this for use as a C wire power supply for a thermostat.It doesn't work as it only is putting out 12 volts, not the 24 as it states.I waited too long to install it, so my bad there.
