Bench Supply

jonclancy · 22nd September 2004, 03:15 PM

Hi,

a quick question, if I may?

I have seen a bench supply with 0-30V output at 3A. Both V and I are adjustable. Output socket are "- " "GND" and "+" in that order.

Daft question

, but could I use this as a split power supply to test a module I have, or is it only good for supplying, say +12V (as opposed to +-12V)?

Thanking you for your advice!!

It sounds like this is a single output power supply. The seperate "gnd" terminal is brought out so that either + or - can be grounded, depending on what is required. So you cann't use it for +-12v.

if you saw it in a store, you could ask them to test it if it puts out dual outputs (+/-) or only single.

it may be possible that it could put out about +/-30V.

For some regulated supplies the GND is attached to the chasis and the mains ground only, this is the case of some of the Lambda supplies which are used in the Physics lab -- there are two floating supplies, i.e. two "+" and "-".

Thanks for the replies!

This is an eBay item I have my eye on. An ISO-TECH model. Looks like it is a single output model. I'll have to get back on there to see if I can root out a more appropriately specced model.

Many thanks!!
