Hi everyone.
There're now lots of comercial power supplies in the market with a high degree of digital features.
Some of them even store all changes in voltage/current in memory. If you just unplug the unit at any time, then power again after a couple of hours, the same voltage/current settings are there.
If even the slightest change in voltage is stored in flash memory inside a microcontroller, it seems not very dependable gear in the long run. Flash memory wears and fails after a heavy use. And I'm not talking about supply where you store the settings whenever you need to. I'm talking about supplies that are continuously writting to memory any minor change.
This seems to be a trend. I'm not saying to go back to just pure analog and potentiometer driven units (which, by the way, seem the most dependable ones), but I wander if this new fancy supplies are made to stay, or to be replaced in a couple of years of heavy use.
What do you think about this?
