Perfect for Video Doorbells
The New House 24V 40AV transformer has been powering my Ring Pro, and a mechanical chime flawlessly for the past month. +Powers Ring Pro without issue despite long wiring run with small gauge wires. +The transformer itself feels solid and appears to be of good quality. +Quiet (no humming sound) +Performance is up to spec (See test section) - Came packaged without bubble wrap allowing it bang around in box during shipping Tests Condition Transformer Output Voltage Input Current Open Circuit 26.2V 77mA 75 Ohm load 25.3V 140mA 50 Ohm load 25.3V 170mA 25 Ohm load 24.8V 260mA Ring + Chime 26.1V 90mA The test indicate that the transformer is well within specifications. -How close the open circuit voltage is to its rated voltage and the small change in voltage under load indicate a well built unit.

    If you had an issue with Ring Doorbell Pro didn't always work or it does work but your indoor mechanical bell rings intermittently or the video recording lags, it is the transformer you need. Don't be fooled by the Device Health in the Ring app. that shows good voltage. In my case it was reported around 4000-4050 mV. The issue was both mechanical bell and Ring didn't get enough supply when they are operating. When calling Ring tech. support they kept saying Ring was fine since it had enough voltage supply which was true, however, they couldn't pinpoint what the problem was with the indoor mechanical bell. Installation was easy. It took me less than 30 minutes from start to finish. Highly recommended product.

      24V at 40VA Transformer My old transformer was16V at 20VA and it was buzzing like a bumble bee rally annoying at night, personally I replaced my transformer with this one because of Ring Video doorbell and finally work much better no waiting to download the video. If someone activates the doorbell the Ring app. opens immediately without a long delay. I can see this transformer to be used in multiple applications like power supply for thermostat or zone valve or intercom in the building. Even motion activation in front of the Ring doorbell has much improved with notifications on the Phone coming much quicker. So if you have been on the phone with Ring customer service multiple times and you did not seen very little performance improvement with all their suggestions. I would recommend you get this stronger transformer. In fact, early on with my Ring research, there was no second guessing with needing a stronger transformer. For some reason, this thought has changed at Ring and the customer service people do not bring it up.

      This is a nice heavy duty 24-Volt transformer. I needed one for my Nest Hello Doorbell. There was a transformer already installed but it was only a 16V and I was looking to get 24-Volts to the Nest Hello Doorbell. It wired up easily, line, ground, and neutral. It has powered the Nest Hello Doorbell with ease and no dropouts so far. I did secure the bracket to the doorbell box to ensure it didn’t fall behind the wall or cause the wires to loosen. It does not come with any connectors. I used wire nuts and electrical tape for the connections.
