Planning a console build using 2x IGFO, 4x insert switcher, 1xMSII and 1xEEQ. Browsing options from MeanWell, how many amps are needed for these boards? Are the mA stated in the build docs (for all except the Insert Switcher) with all relays energized, aka total draw?
I know my additional LED's, meters & illuminated buttons will have to be added. Something like RS-50-25 or LRS-75-24 for the relays/led's, and a couple of RS 1515 or LRS 2515 for the bipolar 15v rails (I presume this works with these supplies, aka psu1 V+ = 15V, psu1 V-=0V, psu2 V+=0V and psu2 V-=-15V. I see that V- is connected to main earth, but through caps and other parts so I'm thinking it would be OK to connect it like explained?) or RS2524's for bipolar +/-18V?
I see RS has a little lower ripple than LRS, so I should choose RS?
Or maybe go for a RT-65C instead (is 0.5 enough Amps on the negative 15v?)?
I don't have much experience with SMPS, but was thinking to run these into something like a couple of TREX
(TIP122/126 + caps & trimmer) for some conditioning of the bipolar audio rails between the supply and boards.
How does this all compare to just getting a suitable dual tapped 15V trafo and running it into a linear supply?
Thanks for any input and all the best,
