Sent Wrong Heaters
Posted: September 5th, 2017, 3:38 am
Purchased some 12V 40Watt heaters, After Receiving the wrong heaters 24v, I decided to Use my spare 24V power Supply.
This was the original Supply for my 3D Printer, A Replacement was purchased because I thought the Original was bad.
After telling the Seller that I would Keep them Because I could Upgrade to 24 Volt system this occurred.
You know they think we are stupid.

I just got to check them out. And before you get worried I will keep them.
This is only because I decided to upgrade the Printer to 24V, Plus not having any 12volt Heaters could not repair It.
Having the spare 24Volt Supply It seemed the Logical thing to do.
You sent me 24V 15R Heaters they were labeled with VHB-AC-5234. I measured them all with an Ohm meter at 16.6 ohms.
However I did order the 12V this NOTE is just for your information (FYI) only.
P.S. I left Positive feed back
Like they would not heat up the hot end... Duh!!!!!!Seller wrote: Hi. Thanks. How did you figure out it is for 24V? Thanks.

It is Simple they are 40 watt heaters.
The resistance is 15ohms
"actually the resistance varied to 16.6. a differences of 1.6ohms "10.6667% not bad tolerance for a, "Power Heater".
voltage / Resistance = Current
12volts / 15ohms = .8amps
PIE
"Voltage * Current = Power "
12Volts * .8amps = 9.6 watts this is not 40 watts
This is what you sent me.
"voltage / Resistance = Current "
24volts / 15ohms = 1.6amps
PIE
"Voltage * Current = Power "
24Volts * 1.6amps = 38.4 watts "This is what you sent me"
