Nice! Thanks for this great info!
Glad it was helpful!
While UL certification is not legally required, it's a really good idea in case you are sued due to a fire. Your device need not even be responsible for the fire, but they could still go after you. And UL isn't the only NRTL which can certify; Any NRTL should be acceptable. I've been thinking of going with Intertek because they're less expensive.
I agree!
For my product I opted to use a pair of AA lithium primary cells for the exact reason you mentioned: It’s meant to be used outdoors or in unconditioned spaces.
I was able to source an off-the-shelf enclosure that includes a compartment and contacts for the batteries. It’s a little expensive (a few dollars in 1k quantity) but works well enough and saves me the cost of tooling.
Thanks for your videos!
Nice job! That's great to hear. Anything you can do to reduce or eliminate injection tooling costs initially is always smart! Thanks for sharing!
@@PredictableDesigns New Age Enclosures, by the way. But there are of course scads of manufacturers out there for OTS enclosures.
As always, thank you so much!!!! Wish your family strong health and get better!!!
Thank you so much!
Thank you so much for this informative video, it's exactly what I needed.
You are so welcome!
Great overview! Thank you! Why not mentioning NiMH batteries? I am about to use 3x AAA batteries to power my ESP product. Main reasons: Rechargable and more safe than Li-Po.
Just what I needed today! Thanks for spreading positivity!
You are most welcome!
Hi, I'm new to product development, and your channel always give me hope! I understand that I can use a UL-certified ACDC adapter for low voltage DC products, but do I still need UL certification, etc. for small DC components like 5-24V motors actually used for the product itself?
No, you shouldn't need UL, but you will still need FCC certification if any part of your circuit oscillates above 9kHz.
CE is just a self-declaration of the manufacturer. Of course the CE-label should basesed on documented facts (that will inplies cost). GS/TÜV for example is an external (and costly) independent certification like UL.
What if you're using only 5-40v AC power do you still need UL certification?
0:00. What about car battery?
Hi there. Have been enjoying this channel. I’m looking to get into the smarthome market. Ok so if I wanted to make a smart plug. Esp32 for the brain and a relay for AC power. 1. Is there someplace that makes the blades that physically go in the outlet? And 2. That would HAVE to get UL listed? Is that why all the imported ones are so cheap? Not listed?
Glad to hear you're enjoying my channel.
My answers are:
1. Yes
2. Yes
Sadly, in Australia we have to certify everything. I use battery power via dry cell batteries and deep sleep. No certification required, unless it has an inbuilt charger. The certification kills a lot of small business runs to get cash flow started.
It's not just Australia, and you need to certify most products in most countries. For example, in the US the only products that can completely skip FCC certification are products with nothing oscillating above 9kHZ, which is exceptionally rare.
It's more a matter of what level of certification is needed, than just whether or not it needs certification.
But, the key point, especially for smaller businesses, is in most cases you don't need these certifications until after you've had a successful sales test with up to a couple hundred units.
@@PredictableDesigns Or make it in China and have the China Export CE stamped on it
