content: HiI have a fluke/phillips PM2813. It is fully working and has 3 channels each of which are 30v @10amp.Excellent power supply. It may not techinically be a bench psu but I have another one sat on my bench and it is excellent.I am looking for £250 for it and it can be collected in East London.

content: I've got one of these. Cheap, 0-30v x2, 2A, better quality than any chinese cack. Gives you 0-30v 4A or 0-60v 2A as you can wire in series/parallel or run two rails off it. No fan either - completely silent and will handle full load output 24/7.http://www.ebay.co.uk/itm/292235857741http://www.ebay.co.uk/itm/382215869413Really, power supplies are power supplies. I'd be just as well off with an HP supply from the 1970s as I would with a new Keysight digital everything unit.Teardown I did here:https://www.eevblog.com/forum/testgear/thurlby-ts3022s-dual-power-supply-teardown/msg1271515/

content: Can't quite agree with the "Power Supplies are Power Supplies" assertion. It's too universal to ingrain into a wide public who may go off and become who knows what.The one you link to seems perfectly fine and for a hobbyist almost anything is, as making an extra filter and a few extra manual adjustments doesn't weigh up to hundreds of euro/pound/dollar.But I personally wouldn't want to go back to the days before my lab had supplies that supported automation. Comes with the caveat that I do also make money off that functionality from time to time, just by the fact I can have my 6.5digit multimeter, several lab supplies and scopes work together to run through a vast array of settings and what not while I go do the shopping or start making dinner. Hour later folders full of CSV's and images to analyse at my leisure.Next stop: My own software in stead of clunky bash scripts.Again, if you're a hobbyist almost anything will do though, I can agree on that sentiment. And if this is the first time you read the word noise especially so.

content: If you just want a decent lab power supply; search ebay for -farnell power supply- excellent quality, analogue lab supply, no uP, no firmware, no BS, does what it says on the tin. Typical British bomb-proof construction. Made 'up North' where men were men. Manuals are available, schematics, etc. and they are repairable, if (and I say 'if') they ever go wrong. Mine must be 40-45 years old, and works perfectly.
