9000 series Power Supply schematic

Mattia, I've got the 9000J installation manual here. DC filter and smoothing unit - 9U, 200kg!!! Are you sure you want to build that!?

I guess it's just a big box of massive inductors and caps; LC filters. That's the only way to filter out the noise without putting too much capacitive loading on the SMPSUs

I did not remember it was so big, can you scan the manual at all?
Im going to have a section on the forum with just schematics.

I've only got the installation manual, it only gives the dimensions for the filter unit. I'm pretty sure there was no schematic in the K service manual. It's a box of mistery!

ok thank you anyway!

so here is some food for thought....
still regarding the switch mode power supply for the 4K...

http://www.groupdiy.com/index.php?topic=49813.0

how about implementing 3 of this per side and create a +-18V @30A and +11V @10A as power supply for the 4K? it would be REALLY cheap...the data sheet says switching frequency it's 200KHz (same as for the lambda psus) and the ripple it's 30mV at maximum current. an equivalent LAmbda one it's 100mV at 25A so summing the 3 boards needed it would still be 90mV per side...not bad...

any thoughts?
Im itchy...I'd like to build it and do some tests on the bench...

Mattia.
