OK, Awesome ONE more question then, can I use the Volker Rack WITH standard 500 series modules like yours ? are they backwards compatible? I want to have the option if I buy any of the 24v modules out there.
First you need to be sure you actually will buy and use a 24V module.
You don't get the 24V for free. The 51X Floor Box PSU has only half the 16V power compared to the VPR version.
Then 99,5% of all standard 500 series modules will fit.
