I had been given this power supply to look at from a Christmas tree light that stopped working.
I plugged it in a draws no load and I put the probes on the dc output and no voltage.
JT-DC24V7.2W-E2Urated=24Vdc Prated=7.2W
Uout=26Vdc tc=75C
24/7.2=3.333 amps
26/7.2=3.611 ampsMade mistake with calculation as Zero999 pointed out.7.2/24=0.3 (300 milliamps)
7.2/26=0.27 (270 milliamps)
I see many of these selling at all sorts of voltages but not with that exact part number or ones with those two different voltages. I have no means of measuring it to find out which as it doesn't power.
I found a video of Bigclive tearing one of these down.

I opened it last night which is a bit different inside to the one Bigclive tore apart and I see no damage and no smell.
Maybe I will post the pictures later.

https://www.ebay.co.uk/itm/255757493895CHANGZHOU JUTAI 24V DC FAIRY LIGHT POWER SUPPLY JT-DC24V7.2W-E1 (CH 1199)
Urated=24Vdc Prated=7.2W
Uout=24Vdc tc=75C
Both 24V.
I am not sure whether the leds need 24v or 26v, what Urated or Prated corresponds to in order to work out the correct power supply and if there are other components that maybe needed on the output as I don't want to blow up the LED'S.
I messaged a few sellers selling them to find out if they sell that exact that model but not response from them.
What do you think?
