DC One
« on: November 06, 2015, 03:40:21 pm »
Looks promising, except that it still requires an external brick supply.  If they made the input range up to 20V then you could at least use an 18VDC laptop brick that most of us probably have.  And it would take very little to just toss on an OLED display and a button or two and forget the PC interface.  PC interfaces are really overrated when you need a minimal set of buttons and/or dials to begin with, IMO.

It is a fail. You can buy fully functional power supplies with more output capability that work without a computer, especially if you account for the actual power source needed.  :--

At which point you are back at the physical format of a bench meter?

I can see the stacking format being neat, and I like the idea of just grabbing a bunch of these and being ready to go for any project - but that doesn't explain why I always prefer Farnell power supplies for their big analog meters and the nice switches.

If this was my first lab and I had unlimited money, I'd probably buy a handful.

A pile of bizarre design decisions, too low voltage, should be sold with a plugpack, shouldn't need two PCBs.

Even it's one distinguishing feature of BT GUI control is crippled by it's ridiculously low information density GUI. For multiple supplies they shouldn't use windows, the GUI should be designed suitable for multi-supply use with the GUI layout corresponding to the physical layout (to slightly reduce the usability loss of not having a quick way to see what wire corresponds to what voltage as you can with a traditional supply).

Piece of s--t.

The terminal blocks wont stand up to repeated connection/disconnection - should have used pluggable ones or standard 4mm Jack socket/binding post combos.

As already mentioned, insufficient output voltage. 

There's no mention of isolation - the output needs to be fully isolated so you can stack them in any combination.  As is, how do you get a negative rail?

Putting USB on each one is *DUMB*.  They are obviously serially controlled (see terminal window) so why not use a single USB <=> serial cable for the whole stacked bank.
