Ring doorbell transformer box12/9/2023 ![]() So did you have an existing traditional doorbell already and you are just adding the Ring unit to that circuit? because THAT is the only time you need the resistor. On 8V it's merely 2 watts (you can assume that 1VA = 1W in this case). With 25ohm resistor, the power always stays within the limits. Ring uses 30VA transformer on their examples, yours has only 10VA on 8 and 16V circuits and 20VA on 24V - but that's definitely not a problem here. The unused terminal should be left unconnected. The most important question would be: is the videobell charging? All of your issues could be easily explained if some of the output terminals are shorted, overloading the transformer. A doorbell transformer is not meant to be precise.) Even a cheapest multimeter would help greatly to ensure you get expected voltages. You could try to use 2 resistors in series (you've linked a 2-pack), especially with 16 or 24V. Contra-intuitively, using higher voltage sometimes resuls in smaller losses when charging an electronic device. You could try using the 8, 16 or 24V taps to see which one works best. The heat load of your resistor also change, depending if the button is pressed. The sound and heat of the transformer change with load. You should observe the transformer running at idle (without any load), with almost-idle load (videobell fully charged), with small load (the videobell charging through the resistor) and at full load (with the bell button depressed / the resistor hooked up directly). Generally, when dealing with a new circuit, the best course is to assemble and run it on a bench first. Cheaply made, loose transformer will make much more noise than a decent unit. The phenomena you're describing are fundamentally normal, but it's impossible to tell from your description if the intensity is normal as well. being fixed to a drywall or lying on a desk. Unless something is acting as sound amplifier (like a guitar body), eg. On a busy day, you should have to put your ear to it in order to notice the sound, easier to feel by hand. A transformer should emit mains hum, but it should be very faint, impossible to hear from a distance. The transformer makes a decent amount of noise. Or wiring it backwards, but that would have blown up already. The only way of giving it too much power would be wiring a 110V transformer (yours) to a 220V circuit. Or do I have to much power being distributed to it? (the transformer is less efficient, but the laptop charger puts much more power so the waste heat should be similar) ![]() On the conceptual level, they do essentially same thing. Is this normal for a transformer?Ī loaded transformer should be about as warm as your laptop charger. The transformer is pretty warm to the touch.Not crazy hot but deff warm. But are the above items normal? Should a transformer be silent and cool? Based on my set up is there any red flags? I guess my overall concern is I understand the very (and I mean very) basics of a transformer and resistor. (Also if I hold it down by hand there is still some light noise) The transformer had the built in clip with the screw (it just goes right into a pop out in the box) but it’s not very secure? I am assuming the noise is from the vibration of it not being very secure to the box. ![]() Is this normal for a transformer? Or do I have to much power being distributed to it? I then souldered the resistor onto my doorbell wiring and hooked up my doorbell wiring to the transformer (distributing 16v to my ring doorbell) Wiring - I hooked the transformer into those. I went ahead and tapped into a junction box which has some 14-2 To my understanding I need to wire my doorbell wiring directly to a 8-24V transformer which has a resistor following their specs. To make a long story short I am in the process of hooking up my ring door bell and I need to follow these instructions: (I want to wire directly to transformer) ![]()
