Seeking Bench Power Supply Recommendations
<< < (3/5) > >>
rdl:
I have a couple of 3610s myself, I bought them used off ebay. One is an Agilent and the other is an older HP. Neither was over $150 including shipping. I actually have six power supplies now. None are switch-mode and none of them have fans. I really, really dislike loud, noisy power supplies.
KubaSO:
In case anyone needed it: I've reverse-engineered the secondary section of the Kepco 620M. The schematics are here:

It's a beast :)

Save a little more and get a Siglent SPD3303X-E Mine is Very Accurate After Calibration using the instructions in the service manual. I think its the only PSU MFG out there that gives Calibration Info. 

Also look for Siglent in amazon Whearhouse deals. Single Channel Siglent SPD1305X go for about 200 shipped.
Wallace Gasiewicz:
 I agree entirely, I believe SMPS work well in the system they are designed for. In a bench supply you don't need spurious signals running amok.
In SMPS applications these spurious signals are outside of the intended device powered. You do not know that is the case when using a bench PS on different devices.
I do like triple PS, when powering gear that requires them, I don't know if you intend to do this.

Don't buy a switch-mode power supply.
Don't buy one of those bare "module" things off ebay.
Don't buy a power supply with a fan.

In many situations, one or more of the above may be acceptable, just not for a first and/or only bench power supply.

I have several of the old HP 6216A supplies and really like them. Built like a tank, very serviceable, and the service manuals are easily available online. Mine averaged $50 70 shipped on eBay. Two can be setup for a +&- supply for opamp circuits.
