This one was sourcing a whole 2mA so not exactly hammered :) ... currently playing with the idea of saying sod it and buying a DP832.

Forum is knackered. Lots of lag and timeouts. Same situation here.

Corrosion boo. Disappointing when you find that in something.

And without any adjustments, it's pretty dead on:



Got a bunch of wirewound resistors arriving tomorrow so will chuck it on load for a few hours and see if it survives!

I forgot to comment on this before. That is a nice supply and it really cleaned up.  :-+ But I'm a little put off by what seems to me a somewhat low current capability based upon it's physical size. I would have expected at least 2 to 3 amps available for the 18 volt output. Am I missing something?

It’s quite low output. 2x20v @ 500mA plus 1x 18V @ 1A is total 40W. However it is totally 100% passively cooled and silent. It’s designed for typical dual rail linear circuit designs with an aux channel for digital logic or something else. They do a 6236B which has 6v @ 2.5A instead of the 18V rail.

Most of the time I’m working with sub 100mA designs so meh. Occasionally I need some grunt at which point it have a monster 15V 30A and less monster 15V 4A jobby.

Yes, the forum is extremely slow.

Fixed the PL310 already. Reseated the driver board connector and all is fine.
