Are they not reliable then?Out of the first four drivers I used out of my order, one was defective right out of the bag. It has a very low input resistance on the supply leads. I hope the rest are fine, but some other members were saying they had similar problems with some of theirs. :thinking:
Sorry that you're having trouble. For the most part they seem reliable to a decent degree.I can't say that mine had it prior to firing it up under load, so the failure that causes the low resistance may not be there initially. It seemed to not pull any current when I first put a supply to it, so look for that.

Paul, it's only some of the pico drives which have had that problem, or others too?
I was setting up an osram PLT5450B 300mA diode tonight with one of Astrals new Picodrives, unfortunately my connection to the diode was loose and it LED'ed, but before i new this, i connected the new Picodrive to my testload and it was fine, still outputting ~250mA, then stupidly, i changed the diode amount on the testload from 4 to 6, without dis-connecting the drive, long story short for a split second the driver had an open-load and....DIED....i know due to the smell of the magic smokeI can't say that mine had it prior to firing it up under load, so the failure that causes the low resistance may not be there initially.
