The new version of Ring Video Door Bell Pro requires a continuous power supply to work. Here is the guide for choosing the right transformer for Ring Doorbell and connecting to the power supply or an existing doorbell power supply. Editor’s Note: The steps explained here need some technical knowledge. We recommend that you get the help of a licensed electrician to perform these actions.
Will My Existing Door Bell Transformer Work for My Doorbell?
A Ring Doorbell with HD videos requires an 8-24V AC. However, Ring Pro requires a minimum voltage of 16V to operate. However, it can go up to 24 Volts. To be safe, your transformer voltage rate can be 16-24V AC. In addition to the voltage rating, you must consider the current rating when shopping for a doorbell transformer. If you have a 16V transformer with a low current capacity, it may not work on your existing doorbell. We bought a 16V 30VA transformer to test with our Ring Door Bell Pro and a Ring Doorbell HD Video version. The transformer rating was good enough to support our Ring Video Door Camera, Ring Doorbell, and our existing doorbell transformer. Those who have an old house (from 1995 and older) were using the low voltage 10V transformer they were using for their doorbell. Also, musical or mechanical chiming doorbells use a low-voltage transformer or built-in power supply. These will not work with a Ring Doorbell.
Insufficient Power Supply Issues with Ring/Nest Door Bell Pro
You may notice one or more issues after you connect your Ring Pro with your existing Doorbell transformer. Even though your transformer voltage rate is sufficient, the transformer’s VA Rating may not be enough to supply your internal and external doorbells. You may notice that your bell is not functioning as expected and see some connection or performance issues.
Your Indoor doorbell may not work. The indoor Doorbell volume is very low. Ring/Nest doorbell shut down or freeze after a button press. Doorbell camera’s intermittent shut down. Camera Live View freezing Wi-Fi network connection issue. Losing the camera’s connection often. Issues with night vision.
If you face any of these issues, it’s time to try a different transformer with a higher capacity. Check below to find out the right transformer for your Door Bell.
How Do I Visually Check My Transformer Capacity?
If your transformer is already working with your doorbell, it’s a matter of transformer capacity. The Ring doorbell recommends 16V AC / 30VA to work with Ring’s Door Camera and Doorbell. The capacity of the transformer (VA), can be visually identified by the thickness of the core. The thickness of the core of the transformer varies depending on the rating. The more current rating Transformer will be bulkier. For a comparison, see the image below with a different VA rating for the transformer. Here, the 16V 10VA transformer with this core and body is not enough to handle the power required for your Ring Door camera and Door Bell.
Best Door Bell Transformers for Ring Pro and Nest Hello
The recommended transformer capacity for Nest/Ring Door Bell Pro is 16VAC 30VA. The previous Ring Door Camera models can also be used the same. We did the research and found the following transformers for most of the Ring Door Bell Camera models. 16V 30VA Transformer (for Single Video Door Bell)
24V 40VA Transformer (for Multiple Video Door Bells)
The 40VA transformer is a high-capacity, compatible with Nest Door Bell, multiple Ring Door Bell Camera Pro, and the Smart Thermostat. These transformers are compatible with multiple Ring Video Doorbells. You can use the same power supply transformer for Nest Hello & Ring Door Bell or Nest Thermostat together. You can try either one of these for your device. These transformers will work even when you upgrade your devices to a higher version that needs more power.
How Do You Check Your Ring Doorbell’s Power Status?
We used the Ring Door Bell HD Camera version for all the screenshots here. This device comes with a rechargeable battery. When we connected this device to the existing transformer, the transformer supply was not enough to power up the device.
You can see the Device Health screen showing “Power Source: Battery.” Either the Ring Doorbell is not getting enough power from the transformer to charge the battery, or the transformer is completely dead.
Ring Door Bell Pro Transformer Voltage
The transfer shows around 17.7VAC at no-load, even though Hoyt is rated for 16VAC. Since the Ring Door Bell supports 16-24VAC, we are good with this voltage rating. Now we replaced our existing transformer with the new one, and the wires are connected to the second connector that goes to the Doorbell. We have rechecked the voltage in load condition to ensure that the transformer supplies enough power and are not dripping any voltage while connecting to the load.
Check the Voltage on Ring Door Bell Panel
Now, you can connect the wires from your old doorbell to the Ring Doorbell panel. You may see three colored wires there, and the green one is the ground. Connect the wires as mentioned in the doorbell user manual. We have rechecked the voltage to make sure everything is working fine.
The ring video’s voltage on the back panel is showing 17.7V, the same as the voltage at the transformer terminals. Everything is working fine as expected, and it is not time to connect the Ring Doorbell to the panel.
Check Ring Door Bell Power Icon
Now that we have checked the Doorbell’s Status on the app and seen the screenshot below. In the second screenshot, the battery icon shows charging.
You can tap on the device health. The power source changed from Battery to “Hardwired” status. Your Ring doorbell is connected to the power source and is working fine. Even though we have displayed all the screenshots with our Ring Doorbell, the same transform and step are applicable for Ring Door Bell Pro, which works only with an external power supply.
