using AC devices with DC
using AC devices with DC
(OP)
So what would happen if I connected a cartridge heater(basically just a resistance) designed for AC to a DC power supply? What about the reverse scenario, a DC device to an AC source?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

This would not be true for a relay coil or something with a significant inductance.

RE: using AC devices with DC
I was using a 240V variac, but would like to use a computer controlled DC psu that I already have(yes I know there are AC pc controlled psu, but funds are not infinite).
RE: using AC devices with DC
If your computer controlled psu allows you to ramp up and down, and is internally fault protected you are lucky and on your way I'd say.

RE: using AC devices with DC
The answer to your basic question is, yes some AC devices will work on DC, and some DC devices will work on AC. Having said that, it is important to eximine each component to see that it is compatable. (switches, relays, motors, coils, SCR's, and surge protection equipment). Even things as small as fuses can be sensitive to being DC operated.

Cartridge heaters are just that.. Cartridges - basically rods with wires coming out of an end.
