NavarisDoor Bell Transformer 8V 12V 24V - for Wired Doorbell Chimes - DIN Rail Mountable 8VA 230V Mains Converter 8/12/24 Volts Output - White

We had one of these installed in our porch about six months ago by a professional. On installation he said there would be the noticeable hum/buzz. It was audible but bearable. The changes must have been very gradual over the remaining months but it did get loud enough that, had been in the house, it would have become intolerable and I would have kindly taken my hammer to it.I say 'remaining' because last Thursday the sound was no finally more and it had died. I was pretty peeved, having missed parcels and needing a doorbell working for the next day so I went on amazon for next day delivery. I was doing my research, checking requirements. I've seen many comments here about sticking with the high street or known in the trade brands. I ultimately went for this brand as I couldn't leave my house that day or next to buy a new one and it was the only one I could get delivered by 1pm the next day. I figured, based on the (negative) reviews, that I probably already had this brand and I should be prepared to replace it again in another 6 months or so.When I opened up my clapped out unit I saw that the professional installer had used the BG (British General) model that everyone keeps saying is the only true quality type. The noisy type, the ridiculously noisy one, the one that became increasingly vocal and then died after 6 months!So I was puzzled but also intrigued to try this version given the comments about how I should only buy BG. I installed this and for the fist time ever....no buzz and it's working flawlessly with the exact same doorbell.Take all the BG brand bigger uppers with a pinch of salt. Perhaps these door bell things are are much of a muchness and some are faulty or infuriatingly loud across all brands but I would certainly not disregard this particular brand over a BG one just because of some negative reviews here. This one was much better for us and it could be for you too. If I update my review here in 6 months time then you'll know it's Even-Stevens :-)

Our house is a 1920's built with an original transformer using 5 volts of power. this was not enough for a Ring doorbell. Having read the reviews this seemed perfect.As I had an existing transformer it was easy to disconnect (obviously makng sure power was off) and connecting this was super easy, make sure you buy the mount for it also, the Wylex ESE2 Insulated Electrical Circuit breaker. Connect the mount first, then this transformer slides and clicks in perfectly. Wires are super easy to connect and away you go.I am no electrician but this is so easy to install, make sure you turn your power off and connect. The transformer has 3 options for power output. connect ne into the '0' output slot then the other wire is slotted in to either 8v, 12v or 24 v slot. For the Ring door bell this needs to be the 24 volt slot.If you are unsure then use an electrician !! but would take 15 mins to install for any novice that is confident with electrics.Obviously this is my opinion if you do this yourself, if you get electrocuted blame yourself and not me !!Great and perfect transformer for your Ring or any other device though..

A bit of a hassle to mount as its intended to mount on a rail. Worked ok once I got it fitted and wired up. I cannot say how long it will last etc.

Purchased to replace one my electrician installed for my smart doorbell. The previous one had a very loud buzzing noise, while this one is basically silent.Relatively easy to install, and seems of good quality.

This is an ideal transformer for bell or chimes, and it has three available output voltages to suit the input of your sound unit. Good buy.

Did not work and did not last beyond a few hours. Started smelling bad and had to be retuned. Noise level was acceptable but power supply was poor or didn’t exist. May be it was voltage range or simply not fit for purpose. Check specifications before buying it. Not so easy to install, it’s bulky and heavy

It's OK no problem

Does the job but found it got progressively noisier over the course of a few weeks and subsequently changed it to a different brand but it worked for the period it was installed for and had it been installed in a different location the noise perhaps wouldn’t have been such an issue. Worked fine for our nest hello , didn’t check what actual voltage it was putting out but had no issues .
