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?
Hi @grelm. Here 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.
Hi @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.
* 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)?
Hi @grelm. I currently don’t have any more information than what has been provided. To discuss more in depth electrical questions about information that is not readily available, please give our support team a call at one of the numbers available here.
