Ring Video Doorbell
RVD1 voltage and current requirements for charging with external transformer?
Hello I would like to permanently supply the RVD1 via an external 24VAC transformer (without external bell). Has anyone already measured this, or are these values known: a) How much current flows through the Ring Video Doorbell 1 using the recommended 25 Ohm resistor and a 24 VAC transformer? b) Which voltage U-RVD exists directly at the RVD-terminals (behind the pre-resistance from the point of view of the feed-in)? c) What actual voltage U-transformer does the transformer provide under the charging conditions? d) What is the minimum voltage required at the RVD1-terminals for permanent supply and charging? Thank you very much.

Hi @grelm. [Here](https://support.ring.com/hc/en-us/articles/205180710-How-to-Connect-Your-Ring-Video-Doorbell-Directly-to-a-Low-Voltage-Transformer-Without-a-Pre-existing-Doorbell-) is the Help Center article for wiring directly to a transformer for the Ring Video Doorbell. For any additional wiring assistance, we recommend contacting a licensed and local electrician.

GHi Tom\_Ring, thanks for your reply. However, your reply and your [link](https://support.ring.com/hc/en-us/articles/205180710-How-to-Connect-Your-Ring-Video-Doorbell-Directly-to-a-Low-Voltage-Transformer-Without-a-Pre-existing-Doorbell-) DOES NOT ANSWER my questions. I asked very specific questions about voltage and current. I did not ask any question for wiring assistance. Btw: I am a licensed electrician! Any idea where or from whom I can get real answers (volt- and ampere-values) to my Questions? regards - grelm

THi @grelm. I've reached out to a support team for some more information on your request. Here's what I was able to find. There is a 25mA max draw~10% per day. The actual voltage the transformer provides would be very specific to that transformer, but roughly 10-50% more than the voltage rating stamped on the transformer. The minimum voltage required would be 8 VAC. I hope this information serves you well.

GHi Tom\_Ring! Thank you very much for your research and update on questions. > @Tom\_Ring wrote: > > ... There is a 25mA max draw~10% per day. .... Just for additional clarification: \* Does that mean, that trickle charging takes place with 25 mA for ~10% per day - which would be ~2,4 hours per day? This would be a charge of 25 mA x 2,4 hrs = 60 mAh per 24 hours? This is really not a lot! \*What is the capacity of the built-in battary of the Ring Video Doorbell (1)? Thanks again - grelm

Hello again! Still no reply? Did I not formulate my questions in an understandable way, or did no one really have the answers? Remark: Please also note the appendix - it should clarify the question. Many thaks - grelm
