Keithley SMU as electronic load?

(1/3) > >>

dzseki:
A question just for sainty. At work we don’t have any electronic load, but we have a few SMUs (mainly Keithley 2612) laying around. If I want to use the SMU as an electronic load the best is to set the desired source current -1x, ie. if I want to dump 1A from a circuit under test (a power supply, obviously) then I set the SMU to „Source I: -1A” is it that simple? Providing that I stay within the power specifications the Keithley.

Mr. Scram:
I've wondered about the electronic load portion of SMUs too and how that'd work exactly. Like whether you could source and sink power with the same SMU or you'd need two units for that.

Yansi:
As the smu (2600) is i think a 4quadrant psu, you can pf course sink and source current. However i woud be very cautious about the dissipated power inside the smu. So please consult the manual thoroughly. It is an expensive piece of kit to get damaged.

Yes, it is that simple.

dzseki:
Thank you for the answers.
Basically what I want to look at the moment is to characterize some low voltage lines up to 15V, and up to 1A. The Keithley is specified for 1.5A up to 20V, so I guess I should be OK dissipationwise.
