BK Precision 1550 bench power supply?

(1/3) > >>

ivan747:
Is the BK Precision 1550 bench power supply a good deal? I know it's a good brand name but sometimes good brands can fail miserably too. What do you think about the digital controls? It is a switching power supply, so is noise a concern?

I like it because is small, fits my budget and will fit nicely in my desk. Also it's got a handy USB port for charging stuff.

I think the voltage / current will suit my needs.

Here's a link to the official site: http://www.bkprecision.com/products/model/1550/switching-dc-bench-power-supply-with-usb-charger-output-1-36v-0-3a.html

Never seen this model before, so my opinion is based just on their website. Seems a bit gimmicky to me. Wonder if this is their own design or badge engineering. I prefer a mediocre linear supply to a mediocre switcher, linear supplies are harder to screw up.

Controls seem clumsy to me, most designs either use analog pots or digital rotary encoders, which are much nicer for adjusting voltage/current. What's the point of digital control if it doesn't support a computer interface or programming? Noise specs are not great, as expected for a cheap switcher. 1-36V seems weird to me, was it so hard to do a proper 0-36V? What if you want to simulate an almost empty AA cell? Some 0.9V logic?

Not impressed by the documentation.

That was the kind of feedback I wanted to listen: real, critical feedback. Thanks.
Any suggestions? I can't afford anything more than a $150 supply. Free shipping would be great, saves big bucks on those heavy transformers.

How about this supply from Circuit Specialists for $119:

It's probably a relabeled Atten supply of some sort.

Multi-turn pots... I'm starting to like this.
I will take look at the manual.

UPDATE: seems to be a little heavy. I hope I don't get nasty surprises with the shipping fees. And by the way, the manual is useless, I can't imagine how the printed one looks like.

What I want to do is to get for under $350:
*A Hakko FX-888 soldering station
*An Extech multimeter, one of those $60 ones with 12 functions and a non-contact voltage probe
*If possible the $50 Amprobe meter Dave reviewed on the $50 shootout.
*If possible (more priority than the second meter) a bench power supply of at least 2 amps and 20V
*A good set of jumper wires (I really need some)
