I just received my Legato v3.10. Thanks.
A question, please: the manual says the Legato draws approx 350mA depending on supply voltage.
Does this mean 350mA draw on each rail? Or would it be approx 175mA on the +ve rail, and 175mA on the -ve rail?

I need to work out suitable component values for my Salas shunt supply.
I've read that the Legato runs a bit hot, so I aim to provide it with a bit under 15V, say +/-13.5V.

Thanks: 1 times
Was thanked: 70 time(s) in 69 post(s)
I'm running at ~ +- 12.5v (wasn't happy @ +-15v, way to hot for me)

Consumption @ 12.5v:

Positive rail = 166mA
Negative rail = 188mA

Great, thanks.
I aim to shunt 60mA per rail, so now I know to set up the CCS of the Salas boards at 230mA +ve, and 250mA -ve.
