Thread: help with an ultrasonic mister

Tweet

I picked up a misting cauldron from goodwill last year and the mister didn't work. I used the cauldron for something else and didn't have time to really research it.

Well, I was messing with it today and it turns out the transformer [plug] is bad. I tested it with another transformer and it came to life. it has a ring of led's around the top and only the blue and red lit up [i'm pretty sure theres 2 other colors].

Ok so here's my question. the transformer it came with outputs 24 Vac at 1200mA. The one I used to test it with outputs 12 Vac at 1000mA. Does this thing really need 24v? Could that be why the led's were acting funny? I didn't let it warm up to full operation because I was worried about this. Can anyone shed any light on this subject? Thanks.

oh here's a picture of exact same mister that I have, even the water level sensor looks the same.

Using an underpowered transformer can be dangerous. The device will be trying to pull more that it can give and the transformer will probably heat up pretty quickly.

It would also explain why all the LED's are not working.

Get another power supply, they are easily bought, just make sure it's at least 24v and a minimum of 1200mA

Sorry, in addition to what I said above. If you cannot find a 24v 1200mA PSU, you can use one with a higher amps rating as long as it is regulated. Most modern (non cheapo) PSU's will be regulated, but check with your retailer if you buy a replacement.

Yes, you have to use a 24v if you want it to work right. The mA aren't as important as the volts and those can be a little different (1500mA will be fine but don't try to use 500mA) but the volts always have to be the same.

yea that's kind of what I thought, but I wanted some confirmation. I'm guessing a 24v power supply is going to be quite expensive damnit. Thanks for the help.

if it is a AC power supply - it won't be regulated! Only DC power supplies are regulated.

thanks guys for confirming.... looks like I won't be able to use it this year, but i'll keep it around maybe for next year.
