<div dir="ltr">I have 2 of the RS-75 12V supplies connected together with the center grounded and it works fine. My only concern with these power supplies is that they may be a little noisy. If you really crank the gain up (I mean a lot!) you will hear the whiney switching sounds that they make. It's not a complete deal breaker because I have not replaced them, but something to consider. Also, so few modules use the 5V, it's easy to just plug a 5V converter into a busboard if you have a module that needs that.<div><br></div><div>Shawn</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Nov 18, 2023 at 12:37 PM Oren Leavitt via Synth-diy <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><u></u>

<p>That will work as long as the + and - outputs are floating,
isolated from ground. The center tap can be grounded in your
system.<br>

<div dir="ltr">I've noticed that most switching power supplies
that offer bipolar outputs(i.e., to get +/-12v) have less

For example, the Meanwell 65B which has +/-12v and +5v, great
for Eurorack, has

<div>What about buying two +12v supplies, or maybe one that
has +12v and +5v with another with just +12v, and hooking them
in series with a center tap to get <a class="gmail_plusreply" id="m_7418947064683935149plusReplyChip-9">+/- 12v? </a></div>

like it's possible, although they only talk about hooking them
up in series to increase the output voltage rather than
bipolar.</div>
<div>Has anybody done this?<br>
