I was asked this question and do not know the answer. I am sure someone here will have one.
My son has to power a hot plate of sorts.....it is 24 VDC.
He said the plate calls for 17 amps max but he has a 10 amp power supply.
Question is....
Will it burn up the power supply or will the hotplate just operate poorly due to not enough power?

Thanks in advance for your input.

If it's a current-limiting power supply, it will reduce the output voltage to limit the sink current to the hotplate.

If it's a basic power supply, it will overload and trip either the output breaker or thermal overload. (we hope)
