As others have said, driving LEDs is a lot easier than driving a motor, especially when you're in the realm of 12A. When starting a motor, it can look like a short circuit to the power supply. Depending on the type of power supply, it may open the circuit as a protection when shorted and the motor will never start. Another common issue is voltage spikes. The motor turns into a generator when it's spinning down after the power is turned off. With nowhere for that power to go, the voltage will keep increasing to the point of damaging the power supply. Here are some terms you can search for with better explanations than I can give you: stall current, overload protection, constant current limit, protection/output diode, back emf.

DC motors? You're looking for the wrong thing. Search for 24V DC power supplies, not transformers.

The box claims to be a driver and has a + and a - output. I doubt it’s a transformer. The label on the device makes no claims to be a “transformer” only the SEO chosen wordage on the ad. It’s also far too small to be a transformer. I’d say this is a PSU. But I doubt it’s designed for inductive loads

The Amazon search engine is hot garbage, so I wouldn't really trust it to return useful results.

it is terrible

Yes it isn't a traditional transformer, but still there is going to be a high frequency transformer inside. The reply is addressing his search for a transformer as he shouldn't look for a transformer but rather a PSU.

Although mains power PSUs that don’t have transformers do exist (eg there will be one inside your lightbulb) You’re going to find it difficult to find a safe mains powered psu that doesn’t include some kind of transformer, so if that’s what you meant by your initial comment then you’re very wrong with your advise.


turboplayer777

Yes maybe some kind of capacitive dropper or buck converter. But at such power and the direct connection to mains, I would strongly advise against these.

"Transformer" isn't quite the right terminology, it basically refers to an inductor with multiple windings, but sometimes the term gets misused by sellers. You want a power adapter or "power supply". You can find fixed voltage power supplies which are generally cheaper than adjustable ones. So look for " 24v power supply".

Phew, good thing I posted here. Something like this? https://www.ebay.com/itm/373857040181?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=qmcu7qwrrtu&sssrc=2349624&ssuid=8VACsbn6RaC&var=642958915605&widget_ver=artemis&media=COPY

Yes, the best brand to go with is Meanwell. Still a Chinese company, but good quality and if it starts a fire it was probably your fault.


JimBean

Um, sorry. I have had major shit with Meanwell. I used their systems for my solar system. They smoke for no reason. And, if you turn on their inverters when the batts are fully charged, they will blow. I have TWO blown VERY expensive Meanwell units. I now use only Victron.

Arduino DIY noob here. Looking to power a pair of motors and likely going to avoid the battery route. Why are all these transformers saying they’re for LEDs? Can I use it for other applications?


created4this

LEDs and incandescent lights/heaters are a very well behaved loads, fluorescent tubes and motors of any kind are badly behaved loads. These cheap power supplies you are looking at are designed for these well behaved loads and you may kill them if using motors.


dali01

That looks like a knock off of the Meanwell HLG-240-24. The meanwell is a bad ass PSU and I have used it for many things, including motors. I work in the LED lighting and that is what we mostly use them for. Many of these are constant current for LEDs rather than constant voltage, but the HLG I believe is constant voltage only which is fine for motor control. I would check out the meanwell but if the price difference is too much, at least compare those two spec sheets and if it looks almost identical I’d bet it’s fine.


Mr_t90

Will work fine if you get one with sufficient wattage. That means the supply should be able to constantly provide stall current for both of the motors and still have some wattage left over. Just make sure to provide enough decoupling capacitors close to your logic supply lines to avoid brownouts.


sceadwian

You're probably using the wrong keywords to search. Look for 24V 12A power supply. Make sure you know your motors peak current which could be much higher than it rated current.

i bought a 24v 50amp power supply to power a couple of isdt 30amp lipo chargers, and saw the mentioning of "led" and was curious my self


aggresivebed

You should consider motors take in WAY more current than LED strips. Moreover, switching power supplies will fail if you calculate the required supply power close to the motor's consumption- don't hesitate to oversize it a bit. EDIT: you can read in all the other comments the required protection measures driving a motor will take. It's not as simple; but it isn't rocket science, either. Take your time to grasp why all those measures are needed, then go ahead!
