Hi,
i have 3 pieces of Meanwell RT65B in my rack and i am quiet happy with it.
the specs are

+12V 2,8A  
-12V 0,5A  
 +5V 5,0A

which is a bit poor on the -12V line.
now i am planning to build a bigger case 197HP x 18U where each of the 6 rows gets one RT65B
I do have a module (WMD Performance Mixer) which is very hungry (430mA) on the -12V line. so i do not have enough headroom for other modules within this row.
it would be possible to add a 2nd RT65B to this row for having one power supply per bus board. but even that is not enough headroom on the bus board the WMD mixer is connected to.

So my question:
is it possible to interconnect all busboards which have a separate power supply?
so my result is 6 pieces of RT65B all connected together in parallel on the secondary lines (-12V, +12V, +5V, GND) for extendig the headroom for all 3 voltages over the entire rack.
As far as i know the voltage won't change as long as it is connected parallel.
thanks for any advice!
