" ...  At power up, the voltage knob changes the output 10V per click.  ...  "
comment
" ...  Easy to set values and turn on and off. ... The constant current and constant voltage behavior is predictable and easy to set up/control. ... Got it to help with hobbyist electronics work at home, and to use with some of my kids projects.  ...  "
comment
" ...  As it turns out, you need to tap the voltage control knob to put it into "Fine" mode and then it adjusts as one would expect. ... I prefer continuously engaged controls but, after getting used to how these controls work, I don't consider this a serious impediment.  ...  "

" ...  It's getting harder these days to find a linear power supply, which this one is.  ...  "
comment
" ...  A while later I needed to increase the voltage and, being more accustomed to a different power supply, reached up to increase the voltage and forgot it was on the 10's digit -- I would have turned it from 5v to 15 volts in one increment which would have fried my entire circuit, but at the last millisecond remembered to check it.  ...  "

comment
" ...  One thing I don't like is how noisy the fan is. ... It's too noisy to keep on full time on my desk (even when only pulling like 1 amp or so), so I had to revert back to a switched supply for what I intended to use this with.  ...  "

" ...  I have a circuit with a current draw that hovers around 1 amp, causing the fan speed to cycle erratically, It drives me absolutely nuts!  ...  "
comment
" ...  It seems like once you start pulling a little current from it, the fans kick on full speed, and you need some earmuffs (exaggerating).  ...  "
