Just because it has a bridge to allow connection of floating +24VDC or -48VDC doesn't mean it is a good idea to apply AC. The input filter caps may not be designed to handle the ensuing ripple current. I would tread lightly in this area.
Not only that, the value of the filter cap in the unit is almost certainly not large enough to reduce the ripple sufficiently, so the internally regulated supplies will, in turn, have more ripple than they should.
In this case, the bridge is not there to be an AC rectifier, it's just there to allow DC of either polarity to work.
Use a DC supply. Best regards, Charles _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
