I recently acquired a new lab supply which was originally meant for an electrophoresis table. As such it has three modes of output... constant voltage, constant power, constant current. (1000v, 200watts, 400ma)
I understand what constant current and constant voltage are, however, I'm confused by constant power. I'm using the supply to charge a highrate SLA and while 400ma will get the job done (highest it goes on constant current), constant power is adjustable from 0 to 200 watts and being able to charge the battery a little faster would be nice.
I could do constant voltage, however, it is way too hard to modify the voltage with precision being as one pot brings it from 0 all the way to 500/1000 volts... imagine trying to get 13.6 on that
As I figure it, constant power outputs the number of watts you specify regardless of output voltage, however, this sounds just like CC which is why I'm confused.
I think if I select 2 watts then it puts out 500ma at 4 volts or 250ma at 8, however, I don't want to risk anything until I'm sure
Any help is appreciated as I try to figure this out... and yes, 1000volts is dangerous...
