Friedland E3539N Bell & Chime Transformer 12 Volt AC 2 Amp

Seems robust and well thought. It is jyst a bit too bulky for me, as it takes 3 spaces in the consumer unit.

I used this transformer for my Reolink Wifi doorbell and it works fine.The terminals on the transformer are a bit naff but it works.

Appears to be a good quality bell transformer, supplied on time and in good condition.

Measured the output as 22VAC with a TrueRMS multimeter, way too high!I'm glad I checked before connecting it.

It produces the voltages that it says it does, I can't hear a hum from it and it has a self resetting fuse in it in case you mess up and temporarily short something out. Perfect for the smart doorbell I used it for

The transformer works perfectly and seems robust and sturdy. But the moment it gets hot (just regular working temperature, not overheating) it start making a very loud buzz that floods the whole room. Might be ok for a garage, but our CU is in the livingroom, I had to replace it with a different brand.

My house has a vintage Friedland Westminster door chime, that had began to chime too softly.A check with a multimeter showed the transformer was failing, it wasn't producing enough amps.It requires a minimum of 0.5amps to work, preferably 1.8amps.This transformer produces 2amps, so its perfect for the task.The replacement fixed the problem.Most doorbell transformers are only rated with 8va roughly 0.5amps, so finding this one was good news.

Not a lot to say really. It's a doorbell transformer. It's totally silent in use, runs very cool and powers my Eufy C31 video doorbell without any complaints. So that's good. What's not quite so good is the fact that whilst it says it outputs 12Vac @ 2A , I measured the output voltage to be nearly double that at 22.8VFortunately my video doorbell will accept transformers in the range 8 - 24 V though. Sorted!
