VIIVRIA 24V 40VA Doorbell Transformer - Heavy-Duty Copper Core for Ring Pro/2 & Nest Hello, Easy Install Hardwired Power Supply, Thermostat/Chime Compatible

Wired to a Ring Doorbell Plus. I learned a lot. First, the Ring doorbell still needs the battery installed despite the hard wired power. Second, it charges very slow but it does charge. Third, the led light around the push button stays on all the time. I understand I should add a resistor or diode but those instructions were not given. Still, the unit is working and was easy to install.

Fast shipping, works great. I had a underpowered transformer (10VA) that was installed in a new build house by the builder. Upgraded and I installed this model and it solved all my issues with my Ring video doorbell (Ring app said I was under powered) and my actual doorbell ringer that would sort of buzz at real low volume with original transformer powering it.

Works as expected on my Nest doorbell camera.

It only lasted a couple hours until nighttime and the camera went into night infrared mode and then quit. I guess the Ring camera uses more power then?

Good quality product. Easy install.

This is what you need if when you install the ring doorbell and it does not work. It gives you the voltage and power supply you need it is quality built and fit perfect in the doorbell ringer box

It takes a while for changing the master code to stick.. got pretty frustrated after 1+ hours of trying and following the instructions

This was a replacement for my multi-zone boiler. It came with everything needed for a professional install. The transformer can be mounted in a steel box with a 1/2 knockout hole or it has the option to mount it with the included 4 bolt pad. I chose a metal box with a cover that had a 1/2 knockout and simply installed the transformer to the plate and tightened with included nut which made for a great tool free install. They really should provide a pic of the optional mount on back side. Wiring is of decent quality a gauge and should provide many years of service. My system uses zone motors to control heat and it handles the load with ease. If you are looking to use this for doorbell solution it would handle the task easily. his was less than half the cost of the same rated unit at the big box stores and greater mounting options. With Amazons fast shipping I never left the house and saved time and fuel running to the stores. Would definitely recommend this transformer for any needs requiring the rated specs.
