Re: 191j PSU question

2006-08-16 by Tony Steventon

Hi Olivier

I checked the 191J circuit and I'm pretty sure the current limit on the 
±15V regulator is about 700mA but I wouldn't load it beyond 500mA. The 
classic setup and 181 keyboard draws about 280mA from +15V, 230mA from -
15V and about 40mA from 22V.  This is all taken from the circuit 
diagrams and not measured so I can't guarantee the info but you can 
clearly drive more than 5 modules and a keyboard from a 191J.  By the 
way the 100m I bought from you is still working well having converted 
the 191J's 100VAC supply to 230VAC.

Best regards
Tony
