    I'm very satisfied. + Sources can be connected in series = symmetrical source (- GND +) or 30V + 30V = 60V. Great for opamp, preamp, amplifier. I needed that 😊 - Sources cannot be connected in parallel. Only one source works at a time, no current flows over the other. Thank you.

    plus : - Well packed, looks nice. - Shown values on the display are as good as correct. (deviations are less than 2%) minus : - A piece of paper with full and clear explanation/description of the different "menu-items" would be more than welcome (or a website) - without extra cooling it can NOT give more than 2 Amps. = 25Watts for charging a 12V battery with power supply 12V, output voltage set to 15V and current limit set to 2 Amps. Setting more output Amps, makes the temperature safety kick in.

    I'm happy with this purchase. It does a good job for a ry reasonable price. It is not necessary to hook it up to an ATX power supply ; all you need to do is hook it up to a 12 volt wall wart. My old ATX units had leaky capacitors, so I was much more comfortable with this simpler approach. I used a plastic chassis instead of metal to avoid the risk of shorting the outputs.

    very good device for make a little power supply Just add an old block for PC or any power block and you havea laboratory power supply with constant currant and/or constant voltage Add a box and an inetrruptor : it work
