I just want to share my recent experience (August, 2019) installing and troubleshooting my install of the Ring Video Doorbell 2 with the Ring transformer.
Looking for a clear statement from Ring in the installation instructions for Ring Video Doorbell Pro regarding the power requirements. What exactly is the ProPower kit? there ard two spa de clips that are some sort of power filtering for the Video? the sticker on the ProPower Kit has accomodation for 2 wires in or out , if you remove the sticker. THe Power requirements for the actual doorbell are even murkier.. there is discussion about 16 to 24 VAC (with unspecified watt/Amp rating) and i see lots of scary references to a Big WireWound resister in some usage cases. Is there a single document that I can use avoid frying my Doorbell or burning down my home? documentation is inappropriate.
It is a bit confusing... there is a help link below for conecting the RVDB1 and 2 direct
ly to a transformer:
Just for info... Voltage and VA what's that? there are a couple of way figures are quoted...
the voltage of the transformer e.g. 16-24V (in this case usually 2 sets of connections allowing you to chose with voltage you want), and a VA number that's the power the transformer can deliver for the set voltage.
So if you look at the 16VAC (voltage alternating current) transformer Ring sells in the US for its PRO model it's rated at:
Power in: 120V AC, 60 Hz
Power out: 16V AC (16VAC) at 30 VA.
The combination of the Voltage supply out and VA rating are key to getting the Ring doorbells to operate correctly. In the case of the Transformer Ring sells it is rated to handle both the Ring doorbell and a powered chime.
In the UK/EU Ring supplies a Transformer with their PRO model that can also be used for the RVDB1 and 2, that has a highest rating of 24V at 15VA which is sufficient to run the PRO Doorbell.
Hey @westerj! To learn more about the Pro Power Kit and installation purposes, check out our Pro wiring diagrams and our article on bypassing your chime kit with the Pro Power Kit.
Depending on your desired use, or wiring configuration, you will find that the above articles show how to install the Pro Power Kit and what transformer voltage and amperage rating is recommended. I hope this helps!
