Honeywell Home Friedland E3538N bell transformer VDE 1

These are the best transformers to use for doorbells. They are simple, straightforward and reliable.

The product is fit for purpose bought it to run a Ring Video Door Bell it was easy to fit but like all electrical products should be fitted by a qualified electrical engineer

I wanted a reliable bell transformer and having had Friedland stuff before I opted for this one. When it came it was actually a Honeywell branded one but had the same model number (i.e. E3538N) and when I researched I found the Honeywell is actually the parent company of Friedland, so I wasn't worried. Honeywell also own the great brand of MK too.. all quality goods I have used over they years, so don't be alarmed if you also receive the Honeywell version, it is literally just the branding, the product is exactly the same. I wanted a transformer for surface mounting (it actually mounts on an aluminium plate in my case) rather than the more common versions that mount inside the Consumer Box onto a DIN rail, as they take up two spaces in the box, and I only had one free anyway. I must point out that this transformer CAN be fitted in a Consumer Unit DIN Rail as well, if you have the space, it is dual purpose, but most transformers that are designed to fit in Consumer Units can't be wall mounted like this one, because they have 'open terminals' where the mains side of the transformer terminals aren't covered, dangerous ! As I had a similar Friedland transformer before (8v rather than this one which is 12v) it made sense to get a replacement that would be easy to wire in, so that I didn't have to change the wiring - it was literally a matter of swopping over the transformer, took me 10 minutes. One thing that wasn't at all clear in the instructions is that I had to remove the little nylon spring loaded fitting that normally 'clips' the transformer onto the DIN Rail of a Consumer Unit. If you put the transformer flat on a table you will notice the one end is lifted up by the this nylon spring. so I pulled the spring (it is really a strip of nylon in a 'U' shape) out, fortunately it came out easily, then I removed the plastic piece that the spring attached too, but that will literally fall out after removing the spring. You MUST remove both of these anyway, otherwise you cannot get the screw though the 'slot' in tha plastic piece I mentioned, once removed you will see there are TWO screw holes that you can fasten the transformer to a wall. The bottom hole (on the mains side of the transformer) is slotted, whereas the top hole (on the 12v side) is a conventional screw hole. I put a screw in the 'slotted; one first, and tightened it enough to secure it but no more, and I then aligned and put in the screw in the normal screw hole, so I could align it perfectly, I then made sure were both tightened but not overtightened ! The final job is to push on the two covers, (they click in place) over the bell side and mains side, so as to literally cover the actual terminals. I did have to widen the cut-out on the mains side cover though, you may have to do the same. Sorry this is so long, but I wanted to cover any problem you might encounter, and that was not covered in the transformers instructions. Still I am very happy with the product and I looks really well, and I am sure will last many years.

Have wired with a Honeywell 3 Series Doorbell Chime and this works fine both charging and ringing the chime. Wanted both to work as found that the announcement on the Nest Display wasn't always working (likely due to kids!). As this is 1.5A this can power both units without fault - the first unit I sourced (a BG branded one) was only able to supply 12v @ 0.6A so was a tad too weak to do both but it would have charged the Nest doorbell fine on its own. My only issue is the terminals were terrible - definitely worth crimping some flat connectors on all wires to make this easier.

Honeywell Honeywell DC915SCV wireless transmitter and reciever, wired as per normal bell and works a treat. 3rd time lucky. Tried 2 other bell transformers, first an 8-16V 2-din rail from an unknown here, then a 12V from screwfix, neither worked properly. Nno chime connector needed, all voltages checked out but doorbell had phantom ringing constantly on the screwfix one and just didn't charge or operate off battery with the former. This transformer is 1.5A so it works fine as it's 16VAC. This proves that the 8VAC that google's own website states the doorbell will operate at is nonsense and incorrect. So I now have a doorbell that works perfectly, keeps charged, responds quicker than it did on battery, works in event of power outage and crucially no more phantom ringing. Shame the Honeywell DC915SCV needs a cr2032 to operate, why it couln't pull a supply off the 12V is beyond me but there we go. Update - since winter has kicked in - nope, this does not work. The nest cam does not maintain a charge and drops when it gets cold or the IR cameras switch on. This means the doorbell intermittently stops working with error messages, or the doorbell of course does not ring. Looking on forums this is a design flaw with the camera itself requiring simply far too much current to operate and it is hence not designed to be fitted to a power source permanently. I've looked in to this and it seems it needs a good 2-3A at 12V, or at least 24-36W, 18W just doesn't cut it. That's more than enough to run a tablet at full pelt, so the designers of the nest cam have done a poor job here given they state 8va is enough. It won't even detect a power source if you try it at 8W power. And the nest wired is still 1st gen in the UK. I am almost ready to give up with the nest eco system and move to something else.

I bought this as I decided to fit a Logitech Circle doorbell, which remains one of the few that is HomeKit and Secure Video compliant. This transformer is needed to provide the necessary voltage to power such doorbells. The product overall feels quality and the terminal screws and end caps are sturdy. After fitting, there is no *hum* as you find with other cheaper transformers. It mounted easily into an enclosure and expect it will do its job for years to come.

Funciona perfectamente con timbre alimentado por corriente continua de Eufy.

Très bonne qualité

Produkt is goed, jammer dat Amazon niet eerlijk is met het geven van garantie.

Werkt perfect voor dubbele gongbel
