Buying notes
Is this the right fit?
- Good fit when
- Use this when a wired doorbell, chime, or compatible video doorbell needs the listed low-voltage power supply.
- Look at another option when
- It is not needed for wireless-only systems, and it should not be guessed at when the existing wiring or voltage is unknown.
- Mounting and fit
- Doorbell transformers mount to a junction box knockout, an electrical panel, or a plug-in outlet depending on the model. Note where the current transformer sits and how its low-voltage side reaches the chime before ordering a replacement.
- Setup note
- Confirm voltage and VA requirements before ordering. Turn off power before wiring, and use a qualified electrician when the transformer is inside an electrical box or panel.
The Craftmade T1630 is intended for wired doorbell systems that need more available power than a smaller transformer provides. Its 16V AC, 30VA rating offers additional load capacity for compatible chimes and lighted buttons.
It is an option to consider for longer wire runs or multi-component systems. Match the voltage and total load to the requirements of the connected equipment before installation; the transformer rating alone does not establish video-doorbell compatibility.

I bought this T1630 transformer along with a new Craftmade doorbell chime to replace the original 40+ year old Nutone doorbell and transformer in my home. I also installed a Lorex doorbell camera and wanted the larger 30W transformer to ensure enough power was available. The transformer is huge in physical size and mounts into an electrical box knockout hole but you can't tighten it up enough to where it won't move around which isn't good. Otherwise the transformer works great and provides sufficient power for both my new doorbell chime and Lorex camera...I highly recommend this transformer despite it's mounting design flaw.
I bought this to allow for the possibility of adding additional chimes. It is overkill for one chime on a short run, but on the other hand, there is plenty of power to ring my one chime very clearly. My one complaint is that it attaches to the box with a set screw rather than a nut (attaching with a nut is MUCH more secure).
I'm happy not only with my 16V 30 watt transformer but also your customer service to help me with this. We needed THREE chimes for this house and this transformer powers them perfectly. We got things wired and now we won't be missing any more deliveries. Thank you!
Works well. Would recommend
Good products good quality I recommend them.
I called 1800doorbell with a problem, and they resolved the issue by telling me what I needed and shipping it to me quickly. I did the repair this weekend and now we have a functional doorbell again.

Answers from our team for T1630 Craftmade 16V 30VA Doorbell Transformer.
What VA doorbell transformer do I need?
Start with the voltage your chime calls for, then pick enough VA (capacity) for the load. A 16V 10VA transformer is usually enough for one chime, one unlit button and a normal wire run. Step up to 15VA, like the T1615 16V 15VA transformer, for two chimes, lighted buttons, or wire runs over about 50 feet. Video doorbells usually need more, so check the doorbell maker's VA range. A transformer with a little more VA than needed causes no trouble; one with too little does.

Do video doorbells need a 16V or a 24V transformer?
Use a voltage that both the video doorbell and the chime accept. Many video doorbells list a range such as 16-24V AC, but many wired chimes are rated for 16V, so a 24V transformer can be wrong for the chime even when the doorbell accepts it. When the chime is 16V, stay at 16V and add VA instead. More VA does not fix a voltage mismatch. Our video doorbell transformer guide goes through it step by step.

Where is my doorbell transformer?
It depends on where the installer put it. Common spots are the garage (near the electrical panel or the garage door opener), the basement or utility area near the panel or furnace, the attic on a rafter or junction box, and inside the wall behind or under the chime box. Following the thin bell wire from the chime often leads to it. See I can't find my doorbell transformer for more places to look.
Answered for Doorbell Transformers & Wire
Can one transformer run two chimes?
Yes, if it has enough VA. A second chime roughly doubles the load when the button is pressed, and a 10VA transformer has little headroom for that. A 16V 15VA transformer such as the T1615 is made for two-chime systems, and the DH910 tri-volt transformer powers up to two low-voltage devices. Both chimes must also be rated for the transformer's voltage.

How can I tell if my doorbell transformer is failing or too small?
Common signs are a chime that buzzes or hums, a weak or partial ding, no ring at all, a transformer that runs hot, or a video doorbell that drops offline or reports low power. A multimeter on the transformer's low-voltage terminals will show whether the output is near its rated voltage. The input side is connected to household power, so turn off the breaker before working on it, or have an electrician replace it.

Understanding Wireless Range: Published Specs vs. Real-World
Why Published Range Differs from Real-World Range When shopping for wireless doorbells, entrance alerts, driveway alarms, and other long-range wireless products, you’ll notice every product lists a maximum wireless range—typically stated as “up to X,000 feet.” For example, the Dakota Alert DCPA-4K-PLUS Driveway Alarm lists a range of “up to 5,000 feet.” It’s important to…
What Is a Wired Doorbell Transformer?
A wired doorbell transformer supplies the low AC voltage a wired chime circuit needs. Its label lists the output voltage and its capacity in volt-amperes. To choose a replacement, match the voltage and capacity requirements in the chime and doorbell manuals, including any requirements for a video doorbell.
