Questions & Answers

Could this support two Ring doorbells at the same time?

If you connect correctly, you will be able to see

Is it usual for them to become a bit ?

It is normal for the transformer to get a little hot when operating. When the temperature exceeds the temperature of the load, a recoverable fuse is located at the output of the transformer, which activates protection and disconnects the output when the load exceeds the temperature

Do you think it will work with the Circleview Doorbell from Logitech?

The answer is yes, if it runs on 24V. It's on my Ring that needs 16- and I have it I have no problems with 24V.

When the ring doorbell 2020 release comes out, will this work?

The new Nest Thermostat works great with this
5/5

Two out of five was the best I could do Adding a wire thermostat to an oil-filled radiator This system relies on radiators and requires a C-type boiler To operate a wifi thermostat, you will need a wire. system has a zoned system, so I have a zone for the non-heating units We did not have an option for a wired thermostat. I saw that some transformers came with wires preinstalled, but I wanted to make a cord that was of a custom length, so that the finished part looked neat. For this transformer, I chose the Southwire 18/2 thermostat wire that is solid copper so that I could cut it to the length I wanted. During the In fact, transformers are not made of solid copper, but twisted wire, so they cannot easily be It looks as if my setup is relatively clean and the thermostat is working perfectly!

On a side note, I had to flip the outlet upside down in order to get the cord to fit, but this is mostly due to the close proximity of my baseboard radiator to the outlet (bad Since the outlet will be mounted on a thermostat, it is not a big deal.

The Arlo Video Doorbell can be used with this equipment
5/5

Because the transformer for the doorbell we have set up in the attic was only providing 12 volts (based on my multimeter), I bought this one. Using a 12-volt transformer will not enable the Arlo Video Doorbell to function. A 24 volt transformer is needed. 1) I purchased 18/2 wire at Home Depot for the installation. 2) The transformer comes with a bolt on top. This did not work for me since the outlet I needed to use was a GFCI outlet without any middle bolt holes, so I had to use a small (6-inch) extension cord to connect the Bolts on this transformer cannot be easily removed because the frame of the transformer prevents the removal of the bolts. Unlike the outlet I used, your outlet may not have a place for the bolt, so you need to come up with a workaround. *3) there is specific information on using the Arlo Video Doorbell with a plug-in. Instead of the transformer I found in my attic, I have a plug-in transformer. If you wish to prevent any damage to your charger plug, you MUST select None for the Traditional Chime option. The AC adapter has an integrated power supply". *
4) use this plug-in With the transformer in place, you won't need the Power Kit that comes with the camera unless you want a chime to pair with the video doorbell.

This adapter lets you connect your doorbell camera to your doorbell
5/5

Are you looking for a doorbell transformer but do not currently have one? Do you just need to replace a dead one and don't want to mess with a hardwiring or paying a contractor? It is this little guy that will take care of business. It was easier and cheaper to get this camera instead of hard wiring in a new transformer when I recently needed to replace my doorbell camera. The build quality is excellent, the adapter feels sturdy and is guaranteed to last for a long time. The device works well with my Amcrest Doorbell Camera and will also work with other devices which require 24VDC.

Definitely one to look for if you live in an old home
5/5

I appreciate you sharing this information with me. If you plug it in, I expect it to work Thru the use of the transformer, my battery-powered Eufy 2K smart doorbell will have a longer useful life. The battery in it is made up of a permanent lithium battery, which concerns me because it is not supposed to degrade. In my New England home, which dates back more than 150 years, I am lucky to have a wood stove. I was able to wire the doorbell with 20 gauge doorbell wire for the 24v capacity with this plugin transformer, so that the doorbell no longer needs permanent lithiums. I wish I had known about this product sooner because I could have saved money on a non-permanent solution. Replace your existing doorbell with a battery-operated one. A big thumbs up for old school technology.

The transformer is a strong and reliable one
5/5

The transformer is what it is. I used it for the sprinkler system control panel, but it can be used for a doorbell, a thermostat or, in this case, a thermostat. A few pros The AC transformers from China, which always seem to malfunction after a year or so, will no longer be needed with this heavy duty replacement. Since there are terminal leads on it rather than an unremovable wear, you can easily adapt it to the situation at hand. A hole has also been drilled into it so that you can screw it into a semi-open outlet This is permanent. In the past 3 years, I've bought 3 of these units and none of them have The cons are I don't really have This coil is made of steel and is heavy, but it is solidly built.

This is a powerful motor, but it's heavy
4/5

When you mount it, be sure to take care of the mounting screws. You won't find wires in the box. Transformers are usually fairly heavy and solid, which is good since it can handle a lot of voltage.

Try to keep an eye out for a mounting screw at the top of the device, oriented the same way as the power plug prongs. You can see it to the left of the picture (It is the little red dot on top of the picture)

When used in an outlet with the correct configuration, this screw will hold the transformer in place. The screw will need to be removed if you want to plug it into a standard outlet or power strip. The only way I could achieve that was by ripping up the paper disc holding it in place with pliers. Additionally, you'll need to include your own cables The list does not include any. All of these aren't deal-breakers, but they do mean that this plug-in isn't for everyone My score was knocked down to 3 stars because it is a plug-and-play solution.

I've had it for months now and so far, it's held up
4/5

In my experience, it has not failed yet and has been used for more than 3 months for a Ring doorbell. The transformers in these units often fail depending on how many times the doorbell is pressed. This is said to cause There has not been any experience of this, and several people have pressed the doorbell already, and it works fine. The transformer is in a laundry room outlet indoors. A buzzing or humming sound may occur occasionally, but it goes away after a short period of time. Thanks to it having a green indicator light, I can tell that it is on and working.

I found the installation to be very simple
4/5

Installation took no longer than a minute on my sprinkler system, so I bought it There are several types available.
