Lab power supply

[dylan0806]

Hi guys,

I'm looking for a bench power supply normally i can use some wall brick I have laying around but I want to upgrade,
I have looked at the Korad KA3005P and found out there were some problems with them in the past.
Do you guys have any other suggestion I would like a double power supply from 0-20V and 0-5A and a budget of 200-350 euro total.

thank you.

Models such as Tenma 72-10495 or 72-2645 or 72-2640 are available from Farnell.

Doesn't Dave sell those in his shop?

I'm using two HP6632A since ~10 years and i'm quite happy with them. Basic specs are matching your requirements pretty well.  They also fit your budget - usually they go for 100-200 US$ used.

Is the 5A per outlet or for the two combined?

If you need the higher current then this will probably mean that you will need to go switched mode which will be noisier than a linear supply. My dual linear supply is 0-32V and 0-2A but I can combine the two to give 4A or 64V.

It might be worth thinking about getting a TTi supply off ebay or, if you can stretch to it, the EL302RD new:

Though this is only 2A per channel or 4A combined.
