Title: Need to know power supply voltages for SL613E test jig
Post by: jwhmca on September 02, 2013, 08:40:42 PM

I need to build a new power supply. Does anyone know the the + and - output values for the stock power supply? I beleive it might be -+ 20dc

Why not try + and -18v first, and measure the pins that will take the voltages to the module. 20v was the early 80's standard that was reduced to 18.5v for better IC lifespan.

Modules are happy with 17v on the bipolar rails, so don't worry too much.

The normal way of using this is with a bench supply(s)

Did SSL sell a power supply with the test jig? Or the idea was to make one?

I built one with 317's so I could just twist them down to 18 or whatever...

Yeah, the idea was it ran via a dual bench supply (or two single supplies joined)

You could make a 1A supply with positive and negative regulators, and run it off that no problems.
