I did not know, nor had I thought to check. So I just did a quick experiment.
Series mode, 3vdc per channel, (6vdc total ch.1+ to ch.2 -), current limit to 1.1 amp per channel,
metering ch. 1 + to ch. 1 -,
shorting ch. 2 + to ch. 2 - :
ch. 1 continues to supply 3vdc, ch. 2 switches to CC mode @1.1A
metering ch. 2 + to ch.2 -,
shorting ch. 1 + to ch. 1 - :
ch. 2 continues to supply 3vdc, ch. 1 switches to CC mode @1.1A
metering ch. 1 + to ch.2 -,
shorting ch. 1 + to ch. 2 - :
both channels drop to 0vdc, both channels switch to CC mode @1.1A each
So I would say it behaves like 2 independent supplies in the case of overload.
(as noted earlier, in both series and parallel modes, ch.2 is the master. ie: the set points of ch.1 are changed to mirror the existing set points of ch.2 when entering either mode. changing ch.2 set points changes ch.1, and ch.1 controls are no longer available)
Hi,
I wonder how the series mode work. I'd like to use it for an opamp dual supply. Does it work just as two independent power supplies of the same voltage connected in series, or do their voltages follow each other in case of overloading (going to the CC mode) just one of them?
