Use an AC relay with DC? Answered
Alright so I want to make something to magnetize screwdrivers with a pulse, basically taking the 400 volts dc from a PSU's capacitors. I have a few relays from some UPSes, however they are all rated for AC except one which also does DC, but significantly less than the AC rating.
The first relay I have s an OEG 0Z-SS-112L
It seems to be triggered by 12v DC, and can take 120vac at 20 amps, 240vac at 16 amps, but on the other side of the relay there is the circuit marking for a switch, with 16a/240v~ and 16a/30v~ on it.
My next relay is an OEG ORWH-SS-112D1F
It's marked for 15a 125vac and 10a 277vac
My next relay is an omron G2r010E, and is markes for 12 amps, either 240vac or 16vdc
My last relay option is a schrack RP 710024, apparently switching with 24vdc and rated for 16a, 250vac
So, can I use any of these with high voltage dc? What is the difference between a DC and AC relay?
